A separately excited DC motor delivers 10 HP at 1,500 rpm, while producing an induced armature voltage of 110 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 RF = 100 2. You may assume that the rotational losses of this motor are negligable. Calculate the motor's overall efficiency in percent.

Question 1 (1 point)
A separately excited DC motor delivers 10 HP at 1,500 rpm, while producing an
induced armature voltage of 110 Volts. The motor's armature circuit is powered by a
DC source V₁ = 220 V. The field windings are powered from a separate DC source
VF = 100 V, and the total field resistance RF = 100 2. You may assume that the
rotational losses of this motor are negligable. Calculate the motor's overall efficiency
in percent.
