What type of motor is illustrated by the schematic of figure "B" of the illustration and what type of starting relay is used? EL-0209

Correct Answer: Option D — capacitor start, induction run motor using a potential starting relay

Capacitor-start, induction-run motors utilize a centrifugal switch or potential relay to disconnect the start capacitor once the motor reaches approximately 75% of synchronous speed. The potential relay senses the back-EMF generated by the start winding to effectively transition the motor from starting to running configuration.
