c) A 20-hp, 220V, 2000 rpm series excited de motor controls a load requiring a torque of TL = 50 N.m at a speed of 1300 rpm. The field circuit resistance is Rr= 150 2, the armature circuit resistance is R, = 0.3 2, and the voltage constant of the motor is Ky = 0.7032 V/A rad/s. The viscous friction and no-load losses are negligible. The armature current may be assumed continuous and ripple free. Determine the; i. amature current I. i. back emf Eg. 111. rated armature current of the motor.

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.
