Answer the following statement(s) true (T) or false (F)
1. Shunt field power supplies are never left energized when the motor is not in operation. 2. Power to an armature is generally supplied by a four-phase, full-wave bridge rectifier. 3. One method of sensing current is to insert current transformers in the three-phase power lines supplying power to the solid-state controller. 4. When a phase-shift control unit senses a voltage decrease, it increases the voltage supplied to the armature until the electro-tachometer is again producing the present output voltage. 5. Feedback control occurs when an electro-tachometer feeds a signal back to the phase-shift unit.
