The role of capacitors in three-phase asynchronous motors 1

A capacitor is a component used to store electric charge, consisting of an insulating medium between two conductors. When a capacitor is connected to a voltage source, positive charges accumulate on one conductor and negative charges accumulate on another conductor, forming an electric field that stores a certain amount of charge in the CLC400AJE capacitor. The size of a capacitor is determined by two factors: the smaller the distance between conductors and the larger the dielectric constant of the medium, the greater the capacitance of the capacitor.diode

In three-phase asynchronous motors, capacitors are usually used as starting motors. Three phase asynchronous motors usually require additional starting assistance to achieve starting, especially when the starting load is high or direct starting may damage the motor. The capacitor starting system provides additional phase difference to the auxiliary starting coil or main coil to change the rotating magnetic field of the motor, thereby increasing the starting torque and bringing the motor to rated speed.diode
