Part winding starters are not suitable for use with delta-wound,____________ motors.

In the part winding motor, the stator windings may be______ connected or delta connected, depending on the motor design.

The thermal capacity of the motor limits the length of acceleration on the first winding to approximately___________ seconds, depending on the connected load.

One disadvantage of the two-step part winding starter is that_______________ .

Part winding starters can be used in as many applications as other, more expensive types of reduced voltage starters.

When selecting heater elements for the overload relays, the electrician should remember that each of the relays carries only____________of the motor current.

Part winding starting has many applications in air-conditioning systems.

Part winding motors are different in construction from standard squirrel cage motors.

Part winding motor windings are intended to operate in series.
