A split-phase motor that has a current relay and a start capacitor is called a(n)

The main idea is how the starting circuit creates torque and how it changes once the motor reaches speed. A split-phase motor uses two windings to create a rotating field, and adding a start capacitor provides a larger phase shift for a stronger starting torque. The presence of a current relay means the start circuit is only connected during startup and is then disconnected as the motor nears running speed. This combination—a start capacitor that is momentarily in the circuit and then dropped out while the motor runs on the induction principle—defines a Capacitor Start, Induction Run motor. The capacitor helps with starting but is not left in the circuit during normal operation, which distinguishes it from capacitors that stay in continuously (Capacitor Run).
