Determine the electromagnetic power, Electrical Engineering

Assignment Help:

A dc shunt motor runs off a constant 200-V supply. The armaturewinding resistance is 0.4, and the ?eld winding resistance is 100 . When
the motor develops rated torque, it draws a total line current of 17.0 A.

(a) Determine the electromagnetic power developed by the armature under these conditions, in watts and in horsepower.

(b) Find the total line current drawn by themotor when the developed torque is one-half the rated value.
