00:00:01,540 --> 00:00:05,260

Let's discuss about Electric Motor Drive system.



2

00:00:09,000 --> 00:00:15,300

The electric vehicle application is not the fixed speed application, and we require the variable speed



3

00:00:15,300 --> 00:00:23,490

driver to achieve the different objective like the system response, changing speed also can vary the



4

00:00:23,490 --> 00:00:29,880

response in terms of how the speed change either fast or slow, that we can see the acceleration and



5

00:00:29,880 --> 00:00:31,030

steady state response.



6

00:00:32,850 --> 00:00:39,870

So really quite the electronics converters and the control system to achieve the desired performance



7

00:00:39,870 --> 00:00:41,400

of the system.



8

00:00:41,430 --> 00:00:42,460

That is the vehicle.



9

00:00:44,070 --> 00:00:50,820

So when we change the control command, we may require the torque response to change fast or slow,



10

00:00:50,820 --> 00:00:56,370

depending upon the application, like if the electric motor is used for the.



11

00:00:58,390 --> 00:01:05,610

Suppose the power dating application, so in our dating application, we required the two fast dynamic



12

00:01:05,620 --> 00:01:10,420

response off thought at the time we gender the come on.



13

00:01:10,480 --> 00:01:17,290

That means when we turn the wheel at the same moment without having any delay, we're required to change



14

00:01:17,300 --> 00:01:19,620

the command or output in dark.



15

00:01:20,000 --> 00:01:22,530

It's called the two fast dynamic response.



16

00:01:23,290 --> 00:01:30,370

But in case of electric vehicle though, because inertia vehicle is high, we cannot get the two fast



17

00:01:30,400 --> 00:01:31,450

dynamic response.



18

00:01:31,460 --> 00:01:38,470

But during the starting, we required the fast dynamic response, increased acceleration.



19

00:01:38,480 --> 00:01:47,830

If our application demands the high power like high powered bike, so too that is the certain objective.



20

00:01:48,700 --> 00:01:50,110

To achieve this objective.



21

00:01:50,170 --> 00:01:57,790

We need to design the electric motor drive system according to the correct objective in terms of response



22

00:01:57,790 --> 00:01:58,760

of dark.



23

00:02:01,400 --> 00:02:08,090

So electric motors required the power electronics component and control system to achieve this objective.



24

00:02:08,480 --> 00:02:14,140

So we are not going to supply voltage directly to the electric motor, but we are going to supply voltage



25

00:02:14,150 --> 00:02:21,530

through the power electronics component to this power electronics block represent the power electric



26

00:02:21,540 --> 00:02:31,520

switches that at that mosfet or Djibouti's its giedre circuit and its protection circuit that call this



27

00:02:31,520 --> 00:02:32,240

number circuit.



28

00:02:33,350 --> 00:02:43,210

So power switches no circuit generally use the components like the capacitor and register and the circuit



29

00:02:43,490 --> 00:02:50,180

are the low power transistor and utilities like the combination of different registers and circuit electrical



30

00:02:51,050 --> 00:02:51,860

parameters.



31

00:02:54,490 --> 00:03:01,900

Control circuit, it may be implemented with the help of Analog Circuit, Digital Circuit Microcontroller,



32

00:03:01,900 --> 00:03:05,250

Microprocessor DSP or FPGA.



33

00:03:05,260 --> 00:03:15,120

S latest trend is the DSP and most popularly used in industry as a control system, the electric motor.



34

00:03:15,130 --> 00:03:18,700

So there are different types of electric motors and their suitability.



35

00:03:18,760 --> 00:03:24,010

We are going to discuss in the succeeding sexer the mechanical transmission.



36

00:03:24,490 --> 00:03:33,310

There are different ways to connect the output that misshaped of the electric motor to the driving wheel



37

00:03:33,790 --> 00:03:37,840

and the various ways to achieve this transmission.



38

00:03:37,870 --> 00:03:40,210

It's called the mechanical transmission.



39

00:03:40,690 --> 00:03:46,070

So this all part combined together form the electric motor drive system.



40

00:03:46,630 --> 00:03:55,360

Yet when we change the control parameter, let me suppose the Thorpdale or acceleration, if we apply



41

00:03:55,370 --> 00:03:59,530

the acceleration, it will result in speed according to the design control system.



42

00:03:59,560 --> 00:04:01,330

This is a very important parameter.



43

00:04:01,900 --> 00:04:04,400

We need to design the proper control system.



44

00:04:04,420 --> 00:04:07,190

It may be either open or closed loop.



45

00:04:07,990 --> 00:04:15,040

So this is the part of electrical engineering to select the power electronics configuration that is



46

00:04:15,040 --> 00:04:22,720

called the topologies, its protection circuit and giedre circuit and the control circuit and electrical



47

00:04:23,020 --> 00:04:23,680

motors.



48

00:04:27,050 --> 00:04:34,730

And combine this blog, it's called Electric Motor Drive in Succeeding Section.



49

00:04:34,760 --> 00:04:43,790

We will also see the different ways of connecting electrical motor to the will, the mechanical transmission



50

00:04:44,300 --> 00:04:44,860

system.



51

00:04:46,220 --> 00:04:48,740

The part of Electric Motor Drive.



52

00:04:52,300 --> 00:04:58,020

It also called the electric vehicle drive train or Electric Drive Train.



53

00:05:00,760 --> 00:05:09,190

The electric motor drive system is a combination of this physical system, our electronic control system,



54

00:05:09,820 --> 00:05:20,950

electric motor transmission system and its representa the way to achieve the desired speed response



55

00:05:21,160 --> 00:05:31,240

of the vehicle and also fulfill the controllability of the speed of the vehicle, not only the controllability,



56

00:05:31,240 --> 00:05:41,230

but it also provide the reason for the regenerative braking or electric braking or reverse martyring



57

00:05:41,230 --> 00:05:49,180

that misreports operation also so all can be possible from the design in the control system and the



58

00:05:49,180 --> 00:06:00,670

electric drive from the more important that all the part of electric vehicle drive system and the combine



59

00:06:01,060 --> 00:06:05,110

when we say the electric vehicle drive, train or electric drive.



60

00:06:05,680 --> 00:06:12,940

It includes the motor transmission system as well as our electronics and its control system to.
