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. [citation needed] . There are two common types of motor capacitors, start capacitor …
How does a run capacitor value affect the motor?
A run capacitor helps a motor run more efficiently, while a start capacitor helps the motor to start up faster (which can save energy). The difference between them is that a run capacitor is constantly engaged in running the compressor, while a start capacitor only engages when the compressor first turns on.
