1 00:00:02,590 --> 00:00:09,490 Let's discuss about iPods, electric motors and their suitability to reapplication. 2 00:00:11,590 --> 00:00:16,540 So there are several ways by which you can categorise electric motors. 3 00:00:18,150 --> 00:00:26,820 If we categorize according to the supply voltage, then we have the same motors that run directly on 4 00:00:26,820 --> 00:00:27,630 this supply. 5 00:00:29,490 --> 00:00:30,510 AC Motors. 6 00:00:31,830 --> 00:00:39,750 That once that is established, the face of single face induction by special type of induction motor. 7 00:00:41,550 --> 00:00:48,040 So it does not require any additional electronic components or any arrangement to run. 8 00:00:48,070 --> 00:00:53,330 So when we supply the disabled from the battery or any other source, it will run. 9 00:00:53,880 --> 00:00:55,620 And same for the AC motors. 10 00:00:55,620 --> 00:00:58,770 When we supply the three phases, the motor is just running. 11 00:01:00,070 --> 00:01:00,430 And. 12 00:01:01,780 --> 00:01:09,160 There are the categories that belong to U.S. mortals, it's called electronically commentated mortise, 13 00:01:09,910 --> 00:01:17,620 so these special categories of mortar's includes the different markers that needs our electronics for 14 00:01:17,980 --> 00:01:20,780 switching and position sensing arrangement. 15 00:01:21,250 --> 00:01:27,760 That means in AC motors, we might require the power, electronics and sensing arrangement that is part 16 00:01:27,760 --> 00:01:29,490 of basically drive. 17 00:01:30,220 --> 00:01:35,500 But if we think about the electric vehicle application, it is not fixed for application. 18 00:01:35,500 --> 00:01:37,060 It is variable speed application. 19 00:01:37,390 --> 00:01:45,340 And so even if the DC Motor Racing Motor Vehicle record, the power electronics controller and converters 20 00:01:45,730 --> 00:01:52,300 so that we need to compare not electric motor only, but electric motor died because of application 21 00:01:52,300 --> 00:01:54,550 is variable speed application. 22 00:01:55,380 --> 00:02:01,720 When we think about the AC motors, it can dramatically on supply, but for limited for the high speed 23 00:02:01,720 --> 00:02:04,240 applications, only for the variable speed application. 24 00:02:04,250 --> 00:02:11,740 It's like when the inverter control algorithm and the C motor also required the power electronics converter 25 00:02:11,890 --> 00:02:14,530 as well as the controller to run. 26 00:02:15,400 --> 00:02:20,580 So when we think about the variable speed application, all motors require the power electronics and 27 00:02:20,590 --> 00:02:26,650 we're switching and position and saying, I don't recall the closed loop, but it's important to the 28 00:02:26,650 --> 00:02:30,760 push and sensing always even for the open look speed control system. 29 00:02:32,230 --> 00:02:39,730 So we'll discuss further about which matters belong to categories, the D.C. murders, there are several 30 00:02:39,730 --> 00:02:47,020 kinds of murder decision to murder this if it is murder and permanent magnet D.C. murders. 31 00:02:48,060 --> 00:02:55,140 So this is it is not as used widely for the TV applications since launching the electric train or locomotive. 32 00:02:56,360 --> 00:03:03,510 And because of its produce, the high starting to square up the crime in the city's. 33 00:03:04,670 --> 00:03:12,150 So this city's motorists ideally prefer it for the electric vehicle applications based on its characteristics. 34 00:03:12,890 --> 00:03:20,110 But there are certain limitations that is high maintenance and competition process. 35 00:03:20,120 --> 00:03:24,070 It requires the mechanical commutator arrangement. 36 00:03:24,470 --> 00:03:28,550 So it's the maintenance cost. 37 00:03:28,670 --> 00:03:37,580 And due to this nowadays, we do not pay for the necessities or the industrial application of electric 38 00:03:37,580 --> 00:03:38,120 vehicle. 39 00:03:39,090 --> 00:03:47,730 So we will find various permanent magnet, this emerging market or the low to the low range, but every 40 00:03:47,760 --> 00:03:55,260 applications, but it has that limitation of Pathankot, so it cannot be used for the very high powered. 41 00:03:56,820 --> 00:04:01,740 High performance electric vehicle application, but we found somewhere in the. 42 00:04:03,320 --> 00:04:09,170 Applications of low power range below lower one kilowatt and so. 43 00:04:14,590 --> 00:04:20,890 Characteristic of BMD is identical to the decision to only set up the son. 44 00:04:22,980 --> 00:04:28,530 Instead of testator winding its way to permanent magnet to produce the magnetic flux. 45 00:04:30,970 --> 00:04:38,350 In a simulator that is induction motor and synchronous motor, but induction motor widely used in the 46 00:04:39,100 --> 00:04:42,220 application because it's a reliable operation. 47 00:04:43,030 --> 00:04:50,680 So when we see the induction motor issues with the driver, only, only the induction motor and permanent 48 00:04:50,680 --> 00:04:56,790 magnets, inkless motors are also nowadays used in various applications. 49 00:04:56,820 --> 00:05:04,090 So we'll also find some way some manufacturing companies start using the permanent magnets. 50 00:05:04,090 --> 00:05:09,660 And but there is also limitation and Sinclair Model S implementation. 51 00:05:10,210 --> 00:05:14,820 So induction motors are really used in every application in modern era. 52 00:05:15,640 --> 00:05:22,840 And if we talk about DC Motors that at Brussels, DC Motors and Switzerland, this market, we know 53 00:05:22,840 --> 00:05:26,200 that brushless DC Motors I use widely. 54 00:05:27,420 --> 00:05:34,680 In the application of electric vehicle from low power to high power range and Switzler to smartarse 55 00:05:34,680 --> 00:05:41,940 are also prepress in various applications, but in electric vehicle application, it is the most suitable 56 00:05:41,940 --> 00:05:42,480 motor. 57 00:05:43,020 --> 00:05:44,280 So it does matter. 58 00:05:44,490 --> 00:05:54,000 Nowadays, we will discuss and compare this some motor necessities more to the MDC induction motor vehicle 59 00:05:54,270 --> 00:05:56,760 in SRM along with its drive. 60 00:05:57,400 --> 00:06:01,830 It is not a good idea to compete only motor vehicle competitor. 61 00:06:03,980 --> 00:06:04,460 Joe. 62 00:06:07,230 --> 00:06:14,970 Before that, we will list out the parameters that required for the electric vehicle application, what 63 00:06:14,970 --> 00:06:18,480 is the requirement of electric vehicle application from the motor drive? 64 00:06:20,030 --> 00:06:22,150 The requirement of dry. 65 00:06:25,360 --> 00:06:31,890 It is different kinds of application because your don't need to be low voltage and high current application, 66 00:06:32,320 --> 00:06:40,420 generally the induction motor and then corporate, if it's 440 volt and the industrial voltage rating, 67 00:06:40,810 --> 00:06:46,000 but we are going to operate it on see link voltage from the battery. 68 00:06:46,300 --> 00:06:48,220 And we are having the. 69 00:06:49,460 --> 00:06:56,780 Capacity from the low voltage to high voltage, depending upon the application for bike. 70 00:06:56,820 --> 00:07:03,950 Currently we are using the county up to 72 world and highest 92 world application for the car. 71 00:07:04,160 --> 00:07:12,630 We also used the 440 volt motors, but not beyond that inside the motor. 72 00:07:12,850 --> 00:07:19,760 So when we convert the battery voltage or we connect the battery in cities and battery packs to attend, 73 00:07:19,800 --> 00:07:20,980 the certain will deliver. 74 00:07:21,380 --> 00:07:22,730 So we do that, are we? 75 00:07:23,750 --> 00:07:28,850 Intruder, we increased the battery voltage with electronic converters. 76 00:07:30,360 --> 00:07:35,720 Because transferral become bulky and costly to put inside the vehicle. 77 00:07:36,330 --> 00:07:44,310 So there is also limitation, but if you use the hourly workers to boost the voltage, required the 78 00:07:44,310 --> 00:07:48,960 higher size up in the car and a and sizable increase. 79 00:07:49,060 --> 00:07:55,380 So we generally try to use the same battery voltage according to the motor rating. 80 00:07:55,890 --> 00:08:03,510 And that's why the motor application will help low voltage and high current applications. 81 00:08:04,240 --> 00:08:10,560 This high current create some issues when we design the power electronics converter for the motor and 82 00:08:10,560 --> 00:08:11,890 its cooling arrangement. 83 00:08:12,240 --> 00:08:17,940 That's why this requirement of electric motors is slightly different than other application. 84 00:08:18,360 --> 00:08:24,930 If we design the motor for the same power for the 440 world and same power for the. 85 00:08:27,150 --> 00:08:34,740 The first 72 hours, so for the 72 year current will be very high for conduct that will be taken, then 86 00:08:34,860 --> 00:08:40,680 there should be proper calling arrangement and inside the cabinet and also the rating of the switches 87 00:08:41,070 --> 00:08:49,320 and its encouragement, all will be a special requirement in case of importance because of high current 88 00:08:49,320 --> 00:08:52,080 application for the same power. 89 00:08:54,200 --> 00:09:00,590 The second thing is we require the high starting to achieve the highest acceleration, which requires 90 00:09:00,590 --> 00:09:01,310 high starting. 91 00:09:05,700 --> 00:09:13,830 As we discussed the stocks with characteristic, we are in right constant power raising so that we can 92 00:09:13,830 --> 00:09:19,570 utilize the maximum power net and efficiency point. 93 00:09:19,980 --> 00:09:23,770 So we are interested in larger and wider question. 94 00:09:23,780 --> 00:09:27,330 Power of the model that is operating within. 95 00:09:27,540 --> 00:09:28,980 It can also be more different. 96 00:09:28,980 --> 00:09:35,790 Characteristics can also be modified with electronic control and control algorithm when we use design. 97 00:09:37,480 --> 00:09:39,890 Really quite the higher power weight issue. 98 00:09:40,120 --> 00:09:45,490 That means for the same power, weight of the motor should be as minimum as possible. 99 00:09:45,790 --> 00:09:51,460 Now we are considering the same material and then we will descend because Mortell include the cost if 100 00:09:51,470 --> 00:09:58,510 we consider the same model from the al-Mutairi adding Fisker, which Marka design will give us the minimum 101 00:09:58,510 --> 00:10:00,930 rate for the same mechanical output power. 102 00:10:04,680 --> 00:10:10,350 Obviously, we are interested in highest efficiency because we are having the limited range and we need 103 00:10:10,350 --> 00:10:17,190 to extend the range, it is a battery operated vehicle and this does require the highest efficiency 104 00:10:17,190 --> 00:10:23,130 as much as possible because currently we are manufacturing the markets in India, according to the I 105 00:10:23,160 --> 00:10:29,640 went in a to rating, but what is going beyond Difford That is premium efficiency, glass and standard 106 00:10:30,060 --> 00:10:37,380 so that we need to concentrate on the highest efficiency in manufacturing process or to the highest 107 00:10:37,380 --> 00:10:43,350 efficiency of not only matter but our own system that your stuff converts to. 108 00:10:47,110 --> 00:10:54,220 As we discussed, the current is high, we record the higher thermal vision capability that Mr.. 109 00:10:55,670 --> 00:11:05,180 The that should be proper cooling arrangement and also very required to hire which capability for the 110 00:11:05,180 --> 00:11:12,860 thermal range, so according to it, change the design of the mortar to allow the cooling as well as 111 00:11:14,780 --> 00:11:17,570 this capability should be higher. 112 00:11:23,850 --> 00:11:26,290 This is something related to duty cycle. 113 00:11:26,520 --> 00:11:32,520 We know that is a continuous duty cycle, monitoring this continuous duty cycle to see some induction. 114 00:11:32,520 --> 00:11:39,360 Martha Stewart in late March in an industry or an industrial fan blower, it is going to run 24 by seven 115 00:11:39,660 --> 00:11:43,410 and we consider it is the continuous duty cycle. 116 00:11:44,490 --> 00:11:51,630 Our friend is also the continuous duty cycle because it is built to run continuously for number of hours, 117 00:11:51,630 --> 00:11:52,980 days in life. 118 00:11:53,220 --> 00:12:00,410 But some mortars that we use for the mixer grinder and blow that use for some minimum minutes, about 119 00:12:00,420 --> 00:12:03,480 10 minutes, 15 minutes, it is a discontinues duty cycle. 120 00:12:03,840 --> 00:12:12,300 So that can be much smaller for the high power rating because we know the thermal limit temperature 121 00:12:12,300 --> 00:12:13,160 increase slowly. 122 00:12:13,170 --> 00:12:20,400 And when we set it down, according to we calculate the thermal dissipation and the power of the mortar 123 00:12:20,730 --> 00:12:23,700 could be high in small and small range. 124 00:12:24,120 --> 00:12:30,360 But to predict the performance in the electrical vehicle application for the duty cycle, it's put off 125 00:12:30,600 --> 00:12:33,930 so that it is categorized in the special duty mortars. 126 00:12:34,200 --> 00:12:42,790 And yet we do not predict how it is going to be performed by the dryer because there is no train driver. 127 00:12:42,810 --> 00:12:50,460 So yet the part comes when the electric motor for the train is the different application because train 128 00:12:50,460 --> 00:12:57,570 locomotive is the application when driver is trained and it is going to run the train an electric motor 129 00:12:57,840 --> 00:12:59,250 through the mission. 130 00:12:59,700 --> 00:13:01,280 A specific procedure. 131 00:13:01,590 --> 00:13:04,200 Yes, our driver is not. 132 00:13:05,290 --> 00:13:12,340 Follow some procedure and come on, stay at different patterns and each driver, each rider will use 133 00:13:12,340 --> 00:13:17,940 their own pattern to accelerate the motor, to accelerate the vehicle to the left. 134 00:13:17,950 --> 00:13:23,000 And it's also vary by time, by time, according to their mind and mood. 135 00:13:23,410 --> 00:13:27,870 So we will observe the large variation in input speed commands. 136 00:13:28,240 --> 00:13:37,420 So we are not only the high starting target requirements, but the thermal vision capability and starting 137 00:13:37,420 --> 00:13:45,970 torque requirements also need to study the switch and how much variation is possible in terms of duty 138 00:13:45,970 --> 00:13:51,340 cycle and even the motorist categories in the continuous duty cycle application. 139 00:13:51,770 --> 00:14:00,280 That is the chance for the large amount of time we reach the big power and big torque that is beyond 140 00:14:00,280 --> 00:14:07,290 the maximum power limit or beyond the return power of the mortar, and that may raise the temperature. 141 00:14:07,300 --> 00:14:13,660 So we record the special protection also calling arrangement also, and we need to consider this point 142 00:14:14,290 --> 00:14:15,610 that need to be sturdy. 143 00:14:16,650 --> 00:14:25,440 According to the application, so every application is very different than all of that application of 144 00:14:25,440 --> 00:14:26,490 electric motor. 145 00:14:26,730 --> 00:14:28,710 As of now, we studied. 146 00:14:32,620 --> 00:14:35,870 Performance stability with temperature variation. 147 00:14:35,890 --> 00:14:42,490 This is very important point, because our motto should perform well in all the temperature conditions, 148 00:14:42,490 --> 00:14:49,830 because our vehicle is not located at one specific industry or one specific location. 149 00:14:49,840 --> 00:14:52,590 So it is going to run throughout the year. 150 00:14:52,780 --> 00:14:53,210 It may. 151 00:14:53,290 --> 00:14:55,690 It is running and some of it is running in winter. 152 00:14:55,690 --> 00:14:58,360 It is running in different locations in different time. 153 00:14:58,690 --> 00:15:01,630 So that should be considered. 154 00:15:01,630 --> 00:15:09,430 The performance of the master and controller should be remain stable and should not deter it with variation 155 00:15:09,430 --> 00:15:10,340 in temperature. 156 00:15:10,660 --> 00:15:18,490 So because this motor is always going to experience a wide range of temperature even in the winter, 157 00:15:18,730 --> 00:15:19,750 during the summer. 158 00:15:19,990 --> 00:15:26,920 So if we consider the thermal capability, it is different depending upon the region and different depending 159 00:15:26,920 --> 00:15:33,490 upon the weather conditions of normal temperature of different countries, and different reason that 160 00:15:33,820 --> 00:15:42,690 we also need to understand when we build the water supplying to the general region so that performance 161 00:15:42,700 --> 00:15:49,270 stability should be studied according to the maximum range of temperature variation. 162 00:15:53,780 --> 00:16:00,810 And is of controllability and its implementation, that means the implementation of control systems. 163 00:16:00,830 --> 00:16:07,830 It should be easy and reliable as well as the cost effective, the controllability. 164 00:16:07,880 --> 00:16:14,810 It means the control lost, control of acceleration, control of reverse, our flow, control of regenerative 165 00:16:14,810 --> 00:16:19,430 braking and control of electric braking whenever it's required. 166 00:16:19,760 --> 00:16:21,110 So all this should be. 167 00:16:22,230 --> 00:16:29,550 Very easy to implement and easy to control, depending on the matter and speed control techniques, 168 00:16:29,760 --> 00:16:32,850 that is akin to the electric drive. 169 00:16:38,140 --> 00:16:46,780 Then we need the high reliability, the reliability of the tests should be high as the vehicle itself. 170 00:16:47,140 --> 00:16:54,300 We are going to run for a number of years, up to 10 or 20 plus years and use the vehicle. 171 00:16:54,310 --> 00:17:01,660 So we want its maximum reliability and we want this maintenance when we consider the motor plus drive 172 00:17:01,990 --> 00:17:10,210 very quick, that maintenance would be a minimum and the manufacturing cost of the markup should also 173 00:17:10,210 --> 00:17:11,460 be minimal. 174 00:17:12,040 --> 00:17:16,240 So many effects and cost, including the material as well as the manufacturing process. 175 00:17:16,660 --> 00:17:19,390 There are certain things when it comes to the process. 176 00:17:20,050 --> 00:17:23,920 Some motus the contract manufacturing cost. 177 00:17:26,230 --> 00:17:33,310 So now we are having this barometer starting to cost and power is in power, which is efficiency, thermal 178 00:17:33,310 --> 00:17:40,060 capability, temperature variation, controllability, reliability, maintenance and caution, I will 179 00:17:40,060 --> 00:17:47,260 compare the different electric motor drive for this barometer's that is required by the motors or electric 180 00:17:47,260 --> 00:17:48,850 vehicle application. 181 00:17:49,570 --> 00:17:52,780 Let's do one by one so we will have the parameter. 182 00:17:52,780 --> 00:18:01,150 We'll compare the necessities, motor, the MDC, motor induction, motor drivability and etc. And yet 183 00:18:01,150 --> 00:18:04,840 we are comparing electric motor drive and not only the motor. 184 00:18:06,560 --> 00:18:13,130 If we consider the starting talk, this emoter has the high starting thought, the implicit drive, 185 00:18:13,490 --> 00:18:16,250 the moderates starting to induction motor drive. 186 00:18:16,490 --> 00:18:21,200 Now, remember, induction motor does not hold the high starting thought, but when we say the induction 187 00:18:21,200 --> 00:18:25,860 motor drive with the help of safety, we cannot get to higher starting thought. 188 00:18:25,910 --> 00:18:26,520 That's right. 189 00:18:26,540 --> 00:18:29,470 I told you, we are discussing induction motor, right? 190 00:18:29,840 --> 00:18:32,580 Because it is better in current scenario. 191 00:18:32,690 --> 00:18:41,060 We are not discussing only motor induction, motor drive and definitely produce the same the SRM. 192 00:18:41,100 --> 00:18:44,150 What this all can produce a high starting thought. 193 00:18:45,560 --> 00:18:46,820 But not the embassy. 194 00:18:49,010 --> 00:18:54,530 If we consider the cost far easier, as we discussed, the required, the higher cost and decision, 195 00:18:55,040 --> 00:19:01,690 it is more debt for the necessities of life MDC as well as the industrial market, that has some limitations. 196 00:19:01,700 --> 00:19:06,410 But we can extend this constant barbarism in the illicit drug and SRM drive. 197 00:19:06,680 --> 00:19:08,980 Much is limited compared to other markets. 198 00:19:09,380 --> 00:19:16,820 So you can see the green light often present can be attained with the reality and SRM drive. 199 00:19:21,330 --> 00:19:30,150 Our weight ratio, so the power of be smarter and policymakers are low because it requires extra components 200 00:19:30,150 --> 00:19:35,820 like the commuter train buses, which includes the weight and induction model, the good part, weight 201 00:19:35,840 --> 00:19:39,080 ratio, good design can also change it from moderate to high. 202 00:19:39,390 --> 00:19:45,840 But the reality is that Democrats more generally in the hyper weight that come with the compact and 203 00:19:45,840 --> 00:19:51,630 smaller size as a markup, which compared to the benefit. 204 00:19:54,680 --> 00:20:02,540 If we consider the efficiency that is in D.C., more efficiency is less with compared to other because 205 00:20:03,470 --> 00:20:07,850 there have been losses in communication and also and. 206 00:20:09,100 --> 00:20:09,580 TheRap. 207 00:20:11,590 --> 00:20:19,930 Competitively, we can achieve the efficiency to the 70, 75 hot beyond 80 percent also, but yet in 208 00:20:19,930 --> 00:20:28,540 this remote area, efficiency greater than 90 percent and selection water efficiency is high with the 209 00:20:28,540 --> 00:20:33,630 help of induction motor play only when it is virtually under control. 210 00:20:33,850 --> 00:20:40,900 And only we can achieve the second point that we need to consider the efficiency with the variation 211 00:20:40,900 --> 00:20:47,410 in load, because we see the variation is lower, that different condition at slow speed, high speed 212 00:20:47,800 --> 00:20:56,500 with the one with the one passenger to passenger, three passenger like the what is the lower accordingly 213 00:20:56,500 --> 00:21:02,530 the efficiency of the motor chain, because modular design is designed to produce the highest efficiency 214 00:21:02,530 --> 00:21:08,650 at certain amount of load, but with lower variation at the light, lower efficiency of induction motor 215 00:21:08,650 --> 00:21:15,640 is reduced, but with the help of modern day, we can achieve the highest efficiency at different range 216 00:21:15,670 --> 00:21:17,110 of speed. 217 00:21:17,110 --> 00:21:24,010 Also, the race and induction motors running at the lower speed efficiencies degraded. 218 00:21:25,050 --> 00:21:26,820 But we cannot use. 219 00:21:26,890 --> 00:21:29,140 We are comparing driving it's high. 220 00:21:29,700 --> 00:21:36,390 Likewise, merely CNN remote has the highest efficiency, even with the variation in law. 221 00:21:36,710 --> 00:21:39,400 Yet we are having the benefit with variation in law. 222 00:21:39,930 --> 00:21:41,760 We are in the highest efficiency. 223 00:21:42,950 --> 00:21:49,340 Because when motor vehicle is running at low speed, we also need to maintain the highest efficiency. 224 00:21:52,250 --> 00:22:00,380 If you compare the effect of temperature variation and thermal concentration, that is, yet it is moderated 225 00:22:00,380 --> 00:22:07,100 list, but part of the MDC, it is high because when permanent magnets comes magnet property, Detriot 226 00:22:07,100 --> 00:22:14,060 and temperature and it effect the overall performance off of the same thing happens for the less, they 227 00:22:14,090 --> 00:22:19,890 say, more far reaching for the permanent magnet because the materials include permanent magnet. 228 00:22:20,210 --> 00:22:25,030 It's also about the effect of temperature, radiation and high temperatures. 229 00:22:25,130 --> 00:22:26,900 Performance of valises like. 230 00:22:29,210 --> 00:22:37,910 So we are having induction that Netzarim has two motors can handle this variation on effect of temperature 231 00:22:37,910 --> 00:22:38,480 variation. 232 00:22:42,220 --> 00:22:49,360 If we talk about the controllability, the D.C. matters and the highest and easiest way to control the 233 00:22:49,360 --> 00:22:56,680 speed of the Murkoff, but for the induction moderated a little bit complex algorithm and to implement 234 00:22:56,680 --> 00:23:01,980 the speed control techniques it's required to detect or control and repeat. 235 00:23:02,350 --> 00:23:11,750 But it's only limitation because high, dynamic, responsive and really quick we need to control on 236 00:23:11,770 --> 00:23:20,200 either side will be synesthetic, can implement the voltage and current controller same way like we 237 00:23:20,200 --> 00:23:21,700 implemented to be smarter. 238 00:23:22,210 --> 00:23:23,980 We can see the speed. 239 00:23:23,980 --> 00:23:30,910 Controllability is somehow easy in the in its attempt to implement it compared to induction motor drive. 240 00:23:33,150 --> 00:23:42,330 Reliability, reliability, prediction market, really, but because of the existence of gross and committed 241 00:23:42,960 --> 00:23:46,140 reliability, if they see us as somehow less. 242 00:23:48,810 --> 00:23:55,740 Let's come to the manufacturing cost, the manufacturing cost of this motor and predicted high cost 243 00:23:55,740 --> 00:24:00,930 of college required the magnets for manufacturing cost is high because the cost of magnets is too high 244 00:24:01,110 --> 00:24:06,320 compared to other components and will also use the magnets, the cost of fuel. 245 00:24:06,380 --> 00:24:08,940 This is also slightly higher than that. 246 00:24:08,940 --> 00:24:10,420 Saddam and Martha. 247 00:24:12,100 --> 00:24:19,400 And this is it is not cost is high because it requires the commutator inverse arrangement and this required 248 00:24:19,440 --> 00:24:22,340 additional process and materials to cost. 249 00:24:22,840 --> 00:24:30,190 Yet in reality, the magnet placement also into the magnet placement, they think includes the manufacturing 250 00:24:30,190 --> 00:24:31,150 process and. 251 00:24:32,120 --> 00:24:39,470 It's also in the manufacturing times, our cost increase, where if we consider that suddenly is having 252 00:24:39,470 --> 00:24:46,250 the simplest structure among the almatov repairing the router with no ending, only the laminated code 253 00:24:46,760 --> 00:24:52,100 and stamping, we need to join together to form the router and state that also in the salient point 254 00:24:52,250 --> 00:24:54,100 in vending is also simple. 255 00:24:54,350 --> 00:25:03,250 The manufacturing, the switch that does matter is the lesson cost and also Foshan process. 256 00:25:03,350 --> 00:25:08,910 All this make it the lowest cost when it comes to manufacturing costs of the Mozza. 257 00:25:12,760 --> 00:25:19,210 If you think about the maintenance and maintenance of this emoter high due to commuter train crashes, 258 00:25:19,540 --> 00:25:26,500 but induction and the maintenance cost is less as we know, same for the similar to more transparent 259 00:25:26,500 --> 00:25:26,850 motor. 260 00:25:27,160 --> 00:25:29,260 The maintenance costs, the less. 261 00:25:34,320 --> 00:25:41,400 So if we look at this table and green number, we can have an idea, ideally three mortar induction 262 00:25:41,750 --> 00:25:48,510 mortar and that Saddam has that a mortar drive, I proofread for the electrical vehicle application. 263 00:25:48,960 --> 00:25:56,130 Yet SRM Drive is more suitable for the electric vehicle application, have restlessly simulators are 264 00:25:56,130 --> 00:25:59,100 used widely nowadays for the electric vehicle application. 265 00:25:59,490 --> 00:26:06,450 But the industry is going to want to switch to smarter because it does not use any magnet and to avoid 266 00:26:06,450 --> 00:26:11,850 the limitation of magnet temperature, radiation, magnetic cost and supply of the magnets. 267 00:26:12,390 --> 00:26:19,200 We are now thinking about the magnet less motor, which having the same kind of performance so that 268 00:26:19,410 --> 00:26:24,820 the switch does not gaining too much attention or the electric vehicle application. 269 00:26:24,900 --> 00:26:25,580 Now this.
