A 220-volt, 20-horsepower compound motor (long shunt, Figure 21–16A) has an armature resistance of 0.25 ohm, series field resistance of 0.19 ohm, and shunt field resistance of 33 ohms.
a. Calculate the current taken by the motor at the instant of starting if it is con-nected directly to the 220-volt line.
b. Calculate the current when the motor is running if the armature is developing 184 volts counter-emf.
