Starting capacitor: An AC electrolytic capacitor or polypropylene or polyester capacitor used to start a single-phase asynchronous motor. The single-phase current flowing through a single-phase motor cannot generate a rotating magnetic field, and capacitors need to be used to separate the phases in order to generate a phase difference of nearly 90 ° between the currents in the two windings to generate a rotating magnetic field. A capacitive induction motor has two windings, namely the starting winding and the operating winding. The two windings differ by 90 degrees in space. A capacitor with a larger capacity is connected in series on the starting winding. When the operating winding and starting winding pass through single-phase AC power, the current in the starting winding is 90 degrees ahead of the current in the operating winding in time due to the action of the capacitor, reaching the maximum value first. Two identical pulse magnetic fields are formed in time and space, creating a rotating magnetic field in the air gap between the stator and rotor. Under the action of the rotating magnetic field, induced current is generated in the motor rotor, and the interaction between the current and the rotating magnetic field generates electromagnetic torque, causing the motor to rotate
