What is a capacitor used for in an electric motor?

In single-phase motors, capacitors help create a rotating magnetic field necessary for starting torque production. Once the motor reaches a certain speed, the capacitor may switch out of the circuit or continue to provide auxiliary phase shift depending on the motor design. Running a motor without a capacitor may be possible in some cases, particularly for small motors or

Motor capacitor

A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field.

What Does a Capacitor Do?

Use a single-phase permanent-split-capacitor type AC motor and wire its lead wires directly to a single-phase power supply (skip the capacitor). The motor most likely won''t run with the load unless the shaft is rotated by an external force (this is much easier with an ungeared, round-shaft motor). This is because we need at least two phases to
