1. A 50-hp, 250-V 1200 r/min dc shunt motor with compensating windings has an armature resistance (including the brushes, compensating windings, and interpoles) of 0.06 2. Its field circuit has a total resistance Radj + Rr of 50 2, which produces a no-load speed of 1200 r/min. There are 1200 turns per pole on the shunt field winding (see figure). Find the speed of this motor when its input current is A. 100 A. B. 200 A. C. 300A. I EA RA 0.06 Ω 50 Ω Radj RF LF IL IF NE= 1200 turns VT = 250 V
