Single-phase motors that use a centrifugal switch to disconnect the start windings cannot be used with variable voltage control. This limits the type of induction motors to capacitor-start capacitor-run and ____ motors.
A) capacitor-stop
B) resistor-stop
C) resistor-start resistor-run
D) shaded-pole

Question

Quizplus · Accepted Answer

Shaded-pole motors do not use a centrifugal switch and are suitable for variable voltage control, unlike motors with start windings that need to be disconnected.
