Capacitor motor with a speed limiting governor device. Start capacitors lag the voltage to the rotor windings creating a phase shift between field windings and rotor windings. Without the start capacitor, the north and south magnetic fields will line up and the motor hums and will only start spinning when phsically turned, creating a phase shift.
Capacitors do not provide the RPM, this is decided by the frequency of the supply in a induction motor, the capacitor provides the correct phase shift in the split phase winding in order to provide the optimum phase angle relative to the supply. Max.
A start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 75% of the full speed, and is then taken out of the circuit, often by a centrifugal switch that releases at that speed.
A capacitor-start induction motor only has a capacitor in series with the auxiliary winding during starting. A capacitor-run motor typically has a large non-polarized electrolytic capacitor in series with the auxiliary winding for starting, then a smaller non-electrolytic capacitor during running.
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).
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.
