Let's discuss about Electric Motor Drive system.
The electric vehicle application is not the fixed speed application, and we require the variable speed
driver to achieve the different objective like the system response, changing speed also can vary the
response in terms of how the speed change either fast or slow, that we can see the acceleration and
steady state response.
So really quite the electronics converters and the control system to achieve the desired performance
of the system.
That is the vehicle.
So when we change the control command, we may require the torque response to change fast or slow,
depending upon the application, like if the electric motor is used for the.
Suppose the power dating application, so in our dating application, we required the two fast dynamic
response off thought at the time we gender the come on.
That means when we turn the wheel at the same moment without having any delay, we're required to change
the command or output in dark.
It's called the two fast dynamic response.
But in case of electric vehicle though, because inertia vehicle is high, we cannot get the two fast
dynamic response.
But during the starting, we required the fast dynamic response, increased acceleration.
If our application demands the high power like high powered bike, so too that is the certain objective.
To achieve this objective.
We need to design the electric motor drive system according to the correct objective in terms of response
of dark.
So electric motors required the power electronics component and control system to achieve this objective.
So we are not going to supply voltage directly to the electric motor, but we are going to supply voltage
through the power electronics component to this power electronics block represent the power electric
switches that at that mosfet or Djibouti's its giedre circuit and its protection circuit that call this
number circuit.
So power switches no circuit generally use the components like the capacitor and register and the circuit
are the low power transistor and utilities like the combination of different registers and circuit electrical
parameters.
Control circuit, it may be implemented with the help of Analog Circuit, Digital Circuit Microcontroller,
Microprocessor DSP or FPGA.
S latest trend is the DSP and most popularly used in industry as a control system, the electric motor.
So there are different types of electric motors and their suitability.
We are going to discuss in the succeeding sexer the mechanical transmission.
There are different ways to connect the output that misshaped of the electric motor to the driving wheel
and the various ways to achieve this transmission.
It's called the mechanical transmission.
So this all part combined together form the electric motor drive system.
Yet when we change the control parameter, let me suppose the Thorpdale or acceleration, if we apply
the acceleration, it will result in speed according to the design control system.
This is a very important parameter.
We need to design the proper control system.
It may be either open or closed loop.
So this is the part of electrical engineering to select the power electronics configuration that is
called the topologies, its protection circuit and giedre circuit and the control circuit and electrical
motors.
And combine this blog, it's called Electric Motor Drive in Succeeding Section.
We will also see the different ways of connecting electrical motor to the will, the mechanical transmission
system.
The part of Electric Motor Drive.
It also called the electric vehicle drive train or Electric Drive Train.
The electric motor drive system is a combination of this physical system, our electronic control system,
electric motor transmission system and its representa the way to achieve the desired speed response
of the vehicle and also fulfill the controllability of the speed of the vehicle, not only the controllability,
but it also provide the reason for the regenerative braking or electric braking or reverse martyring
that misreports operation also so all can be possible from the design in the control system and the
electric drive from the more important that all the part of electric vehicle drive system and the combine
when we say the electric vehicle drive, train or electric drive.
It includes the motor transmission system as well as our electronics and its control system to.
