A separately excited DC motor delivers 10 HP at 1,000 rpm, while producing an induced armature voltage of 200 Volts. The m armature circuit is powered by a DC source V₁ = 220 V. The field windings are powered from a separate DC source VF = 100 V the total field resistance RF = 110 2. You may assume that the rotational losses of this motor are negligable. Calculate the mot overall efficiency in percent.
