A dc motor with armature resistance is fed from a step down chopper in the continuous mode, and operates at some known speed and known excitation current. The motor current rises from in the ON period of the chopper; and drops from in the OFF period of the same circuit. Both the rise and fall of the current may be assumed to be approximately linear.
What is the average power loss in the machine armature?
