[citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).

Why is a capacitor necessary for a 1 phase motor?

Capacitors are used in single-phase motors to create a phase difference between the currents in the start and run windings. This phase difference creates a rotating magnetic field, which is necessary for starting torque and running the motor. That’s why a capacitor is necessary for a 1-phase motor.

Do you need a run capacitor for a motor?

They have relatively high losses and low efficiency and are not designed for continuous duty; it is necessary to disconnect them once the motor gets up to speed using a centrifugal switch or relay of some kind. A run capacitor is used to smooth the motor's torque during each revolution, increasing efficiency and performance.

Do AC motors need a capacitor?

Some AC motors require a “capacitor” to power the secondary phase coil (auxiliary coil) to create a rotating magnetic field while the engine is running. Running conductors are designed for continuous operation while the motor is powered, therefore electrolytic capacitors are avoided and condensers with low loss polymers are used.

How to choose a capacitor for a motor?

Capacitance Value: Make sure the capacitance matches your motor’s requirements. A start capacitor, for example, needs a much higher capacitance than a run capacitor. Voltage Rating: To avoid potential failures, always choose a capacitor with a voltage rating higher than what your system will use.
