1 00:00:01,410 --> 00:00:12,090 In this situation, we will discuss about the characteristics of vehicle for the ICC and Eevee, but 2 00:00:13,980 --> 00:00:23,670 let's discuss about the force field characteristics of icy icy engine with vehicle vehicle is basically 3 00:00:23,670 --> 00:00:24,240 mass. 4 00:00:24,240 --> 00:00:30,000 If we applied the force, it will result in linear motion and it will attend certain speed. 5 00:00:30,870 --> 00:00:39,990 So on x axis, that is the speed of the vehicle in kilometer per hour and on y axis, the applied force 6 00:00:39,990 --> 00:00:41,380 to the vehicle. 7 00:00:41,790 --> 00:00:50,480 This force is generated in the icy bay, the vehicle with the engine. 8 00:00:50,880 --> 00:00:53,880 So this engine produced the force. 9 00:00:53,880 --> 00:01:01,820 It is linear cylindrical, then it is converted into motion and tangential force applied to the wheel. 10 00:01:02,160 --> 00:01:08,910 Considering the constant radius of the wheel, the tangential force is driving force that drive the 11 00:01:08,910 --> 00:01:11,190 vehicle and result in the speed. 12 00:01:11,610 --> 00:01:20,830 So that is what forces speed characteristic is represent a platform that is generated from the icy and 13 00:01:20,830 --> 00:01:22,170 which resulting speed. 14 00:01:22,560 --> 00:01:22,980 But. 15 00:01:24,310 --> 00:01:31,870 I see engine cannot produce the very high starting torque for the Hill climbing without the arrangement 16 00:01:31,870 --> 00:01:41,980 of variable gear, so we required the variable gear system to meet the both the requirement of starting 17 00:01:41,980 --> 00:01:43,560 torque or the hill climbing. 18 00:01:43,780 --> 00:01:48,710 And let's for the cruising speed, high speed operation and load load. 19 00:01:49,450 --> 00:01:53,530 So to meet this requirement, we must have to use the different gear. 20 00:01:54,410 --> 00:01:59,920 The difficult will, of course be characteristics is given. 21 00:02:00,430 --> 00:02:05,230 The speed of the vehicle is kilometers per hour and force is in low. 22 00:02:06,750 --> 00:02:14,520 So then is the maximum value this is for considering the typical value for the car you can see in the 23 00:02:14,520 --> 00:02:20,190 first get, the vehicle can attain certain maximum speed. 24 00:02:20,220 --> 00:02:24,560 But beyond that, it cannot reach the higher speeds. 25 00:02:24,570 --> 00:02:30,690 So to achieve the speed, as we already know, we need to change the game from third to second, third, 26 00:02:30,900 --> 00:02:32,010 fourth and fifth. 27 00:02:32,460 --> 00:02:40,310 So fifth, get will the high speed, but the target will be less as per the requirement. 28 00:02:40,320 --> 00:02:48,670 We require the variable gear arrangement in the engine with vehicle separate conventional vehicle. 29 00:02:48,780 --> 00:02:52,140 We needed the variable gear. 30 00:02:53,040 --> 00:03:02,780 If we block the engine speed versus the vehicle's speed, then for the different gear it will be look 31 00:03:02,790 --> 00:03:03,540 like this. 32 00:03:03,810 --> 00:03:10,980 Now on the x axis, that is the vehicle speed in kilometers per hour and maximum speed is considered 33 00:03:11,040 --> 00:03:14,690 for, in this case, for understanding 6000. 34 00:03:15,150 --> 00:03:19,140 And if you consider the gear arrangement, then first gear. 35 00:03:19,290 --> 00:03:26,220 Second gear target for all gear makes it will remain almost six thousand for the engine speed. 36 00:03:26,580 --> 00:03:30,930 But with the gear which transferred the talk from the. 37 00:03:32,500 --> 00:03:42,820 Engine to the will and will speed will decide the vehicle speed, and so that vehicle speed is will 38 00:03:42,820 --> 00:03:51,160 be change with maximum speed will depend upon the gear, but maximum engine speed for all it is seem. 39 00:03:51,520 --> 00:03:58,600 So, yeah, it can develop the high court with the forget it, forget it can produce to hire vehicle 40 00:03:58,930 --> 00:03:59,460 speed. 41 00:03:59,800 --> 00:04:09,220 So the gear requirement is matched in case of I say vehicle and engine is not capable to directly provide 42 00:04:09,220 --> 00:04:13,780 the various torque requirements during starting and high speed operation. 43 00:04:14,810 --> 00:04:22,630 The engine cannot provide the all requirement of the vehicle during starting as well as at the high 44 00:04:22,630 --> 00:04:22,990 speed. 45 00:04:22,990 --> 00:04:25,300 So we must need to use the gear. 46 00:04:26,620 --> 00:04:27,010 But. 47 00:04:28,530 --> 00:04:36,120 Let's observe this fourth speed characteristic of electric vehicle, in this case, this force is produced 48 00:04:36,120 --> 00:04:37,210 by the motor. 49 00:04:37,620 --> 00:04:38,840 So what is the already? 50 00:04:39,070 --> 00:04:47,310 So when we say the Ford produce at the South End, it is due to the dark and digital force multiplier, 51 00:04:47,330 --> 00:04:50,970 whether it is and the talk is transferred to the vehicle. 52 00:04:51,420 --> 00:04:57,550 So the gate arrangement yet again produced high starting top as well. 53 00:04:57,660 --> 00:05:02,680 This is the constant region and then torque will reduce with the increase in speed. 54 00:05:02,880 --> 00:05:09,840 This is the typical speed or characteristic you can see and thought if we consider the radius constant, 55 00:05:10,770 --> 00:05:12,490 then we can see the force. 56 00:05:12,900 --> 00:05:20,730 So if you consider the wind speed in R.P.M. or in the Iranian position, then we can also have the same 57 00:05:20,730 --> 00:05:23,160 speed or characteristic of motor. 58 00:05:23,400 --> 00:05:28,080 But here we have drawn the speed for speed characteristic of the vehicle. 59 00:05:28,320 --> 00:05:31,710 So this is the speed of the vehicle in kilometers per hour. 60 00:05:32,250 --> 00:05:40,160 And this force produced by the electric motor that drive the vehicle, the driving force to the vehicle. 61 00:05:40,920 --> 00:05:51,070 And because in this case, we do not require the get arrangement because the electric motor that produced 62 00:05:51,070 --> 00:05:54,690 the driving force is capable to produce the high starting torque. 63 00:05:56,350 --> 00:06:06,790 As well as it can produce the high speed, so the benefit we will achieve with the electric vehicle 64 00:06:06,970 --> 00:06:14,650 with compared to icey vehicle is that we do not require any more the variable gear system. 65 00:06:15,140 --> 00:06:22,810 Still, I am not saying the careless operation, but I am saying fix gear and variable gates electric 66 00:06:22,810 --> 00:06:23,250 vehicle. 67 00:06:23,890 --> 00:06:26,380 We can have fixed gear system. 68 00:06:27,940 --> 00:06:35,980 If we look at the fiscal system for the considering the induction model, I selected the typical will 69 00:06:36,040 --> 00:06:47,560 up to speed in terms of R.P.M. Revolution Parmeno 10000 to R.P.M. and vehicles is 200 kilometers per 70 00:06:47,860 --> 00:06:48,220 hour. 71 00:06:48,910 --> 00:06:58,360 So in the fixed gear operation, because models capable to produce the high talk and the low speed with 72 00:06:58,360 --> 00:07:05,920 the help of different electronic converters and dry opposition variable frequency drive the decision. 73 00:07:05,920 --> 00:07:12,970 Different methods are there, which can produce the high starting target low speed without having the 74 00:07:13,390 --> 00:07:15,020 variable speed get. 75 00:07:15,970 --> 00:07:16,960 So what is the fix? 76 00:07:16,960 --> 00:07:26,470 Gap is design is also easy and because this fix gap is generally Planetree type that the center is Sungai 77 00:07:26,470 --> 00:07:29,350 and surrounded planetary set in stone. 78 00:07:29,800 --> 00:07:38,080 So there is also a reduced complexity in design of the system because we need to match only the maximum 79 00:07:38,080 --> 00:07:43,780 speed of Marter with the desired maximum speed of Wakan then. 80 00:07:44,860 --> 00:07:47,690 It will remain the linear. 81 00:07:48,010 --> 00:07:56,470 So what we need to design to all what folks get and we do not need to change gear as we are changing. 82 00:07:56,470 --> 00:08:02,480 And I think in this week that this is the one advantage of the electric vehicle. 83 00:08:11,150 --> 00:08:18,980 If we compare the variables perkier versus the fixed, Felgate admits, I see physical with compared 84 00:08:18,980 --> 00:08:20,770 to electric vehicle that. 85 00:08:22,280 --> 00:08:30,170 Propelled by the electric motor and we can fix Bill Gates system reduces the size, weight, cost and 86 00:08:30,170 --> 00:08:32,660 overall complexity of transmission system. 87 00:08:34,460 --> 00:08:41,780 As well as absence of changing offers, smooth driving experience, and it enhanced Rasmusson efficiency, 88 00:08:42,230 --> 00:08:42,510 too. 89 00:08:43,340 --> 00:08:51,200 We are not discussing about the girls operation, but get into mostly planetary gear system. 90 00:08:53,480 --> 00:09:00,290 So hope you got an idea about the forward speed characteristic of the vehicle and the comparison of 91 00:09:00,530 --> 00:09:09,130 see an electrical vehicle for their speed characteristics and fixed versus variable speed gear.
