Capacitor Motor
The start windings and capacitor are designed to complement each other so the magnetizing force is approximately equal to that of the run windings. The result of having the capacitance is almost a 90° phase shift between the currents through the run windings and start windings. This reduces the magnetizing currents in the rotor, reducing copper losses, and

Types of Capacitors: Definition, Diagram, Working, Uses [PDF]
The types of capacitors are categorized as follows based on polarization: Polarized; Unpolarized. A polarized capacitor, also known as an electrolytic capacitor, is a crucial component in an electronic circuit. These capacitors are used to achieve high capacitive density. Unpolarized capacitors are preferred over fully charged capacitors.
