Q. A 10-hp, 230-V dc shunt motor takes a full- load line current of 40 A. The armature and field resistances are 0.25 and 230 , respectively. The total brush-contact drop is 2 V, and the core and rotational losses are 380 W. Assume that stray- load loss is 1%of output. Compute the efficiency of the motor.
