The role of capacitors in electric motors 1

A capacitor is an electronic component used to store electric charge, primarily characterized by its ability to store charge between two conductors. The unit of capacitance is the farad (Farad), which represents the ratio of the charge on the capacitor to the voltage across it. In a circuit, a capacitor consists of an insulator between two conductors, where one conductor carries a positive charge and the other a negative charge, creating an electric field that results in a potential difference between the two conductors.diode

In electric motors, the function of capacitors primarily manifests as auxiliary roles during the starting and running processes. The DS8921AN capacitor is commonly used as an auxiliary component for motor starting, providing additional starting torque to facilitate rapid motor startup. Additionally, capacitors can be employed for power factor correction by improving the circuit's power factor, reducing losses from reactive power, and enhancing system efficiency. In certain specialized motor designs, capacitors may also serve to regulate speed and improve operational efficiency diode
