Answer the following statement(s) true (T) or false (F)
1. A concentrated-field universal motor is usually a salient-pole motor with two poles and a winding of relatively few turns.
2. Universal motors are speed-regulated by inserting resistance in parallel with the motor.
3. In a universal motor, severe arcing at the brushes from changing the direction of rotation is prevented by shifting the brushes to the neutral (sparkless) plane or by adding a compensating winding.
4. Although conductively compensated motors have a low starting torque, the speed regulation is very good.
5. Article 430 of the National Electrical Code® provides requirements for the motor branch-circuit overcurrent protection, motor overcurrent protection, and wire sizes for motor circuits.
