Please help me solve this question in details and fully explaination. Thank you so much in advance.

A separately excited DC motor delivers 10 HP at 1,500 rpm, while producing an induced armature voltage of 170 Volts. The motor's armature circuit is powered by a DC source VT = 220 V. The field windings are powered from a separate DC source VF = 100 V, and the total field resistance R3: = 160 Q. You may assume that the rotational losses of this motor are negligable. Calculate the motor's overall efficiency in percent
