A motor capacitor 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. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).
This technical paper discusses the larger motor-run capacitors (330 Vac to 440Vac and 20 to 50 μF) for 1/4- to 1-Hp motors. This article covers some of the evolv-ing liquid-filled polymeric film capacitor technology advances which are continu-ing to improve motor-run capacitor efficiency.
The input parameters of a single-phase capacitor-start, capacitor-run induction motor are investigated through simulation and experimental results under normal power frequency operation. The performance of the above single-phase induction motor is analyzed for different load conditions.
Run capacitors are designed for continuous duty while the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used. Run capacitors are mostly polypropylene film capacitors (historically: metallised paper capacitors) and are energized the entire time the motor is running.
Some single-phase AC electric motors require a "run capacitor" to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running.
IEC /EN 60252-1 2011 specifies the following levels of protection for motor run capacitors: S3 – fail open-circuit only. A motor capacitor which is a component of a hot tub circulating pump can overheat if defective.
