Fan Capacitor Dry / Oil

Fan Capacitor stores energy and provides extra power for the fan motors when they are running. Since a fan is expected to be operated just by the flick of a switch, it has to employ a continuous rating capacitor in series with its auxiliary winding, which stays energized as long as the fan runs. All Capacitors are designed for continuous duty and with minimum capacitance droppage which decreases the Energy Cost and also increases the lifespan of the fan motor. Available in: Dry Type in Aluminum & PP Can / Oil filled in Aluminum Can and Dry Type PP box type

Motor Run Capacitor

MOTOR RUN CAPACITOR Single-phase AC electric motors require a “Run Capacitor” to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Motor run capacitors are designed for continuous duty while the motor is powered. Run capacitors are mostly polypropylene film capacitors and are energized the entire time the motor is running. Motor run capacitors are also usable for general sine wave applications such as filters, inverters, UPS devices, etc. Available in: Dry Type in PP & Aluminum Can in both Pin & Wire type

Motor Start Capacitor

MOTOR START CAPACITOR briefly increase motor starting torque and allow a motor to be cycled on and off rapidly. A start capacitor stays in the circuit long enough to rapidly bring the motor up to a predetermined speed, which is usually about 75% of the full speed, and is then taken out of the circuit, often by a centrifugal switch that releases at that speed. Afterward the motor works more efficiently with a run capacitor. StartCap 250V Series Capacitors are manufactured in PP Cylindrical case and designed for use in any Motor Start Application. Available in: Dry Type
