Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.

Question

b) Draw the speed control block diagram of the DC motor, which can be controlled with armature voltage and field flux with 3 phase AC-DC driver, and explain how the speed control is done.
