Capacitors are like short-term energy banks for electrical circuits. They consist of two plates separated by a dielectric material, which stores energy when a voltage is applied. Motor systems can give an initial power boost during startup or smooth out power fluctuations while the motor is running.
A motor capacitor is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor).
There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor). Motor capacitors are used with single-phase electric motors : 11 that are in turn used to drive air conditioners, hot tub / jacuzzi spa pumps, powered gates, large fans or forced-air heat furnaces for example.
Capacitance Value: Make sure the capacitance matches your motor’s requirements. A start capacitor, for example, needs a much higher capacitance than a run capacitor. Voltage Rating: To avoid potential failures, always choose a capacitor with a voltage rating higher than what your system will use.
Some AC motors require a “capacitor” to power the secondary phase coil (auxiliary coil) to create a rotating magnetic field while the engine is running. Running conductors are designed for continuous operation while the motor is powered, therefore electrolytic capacitors are avoided and condensers with low loss polymers are used.
The role of the starting capacitor is to lag the current in the auxiliary winding, bringing these two currents out of phase. When the rotor reaches sufficient speed, the auxiliary coil is disconnected from the circuit by means of a centrifugal switch, and the motor remains powered by a single coil creating a pulsating magnetic field.
Motor run capacitors are designed for continuous duty, and remain powered whenever the motor is powered, which is why electrolytic capacitors are avoided, and low-loss polymer capacitors are used instead. The capacitance value of run capacitors is usually lower than the capacitance of start capacitors, and is often in the range of 1.5 µF to 100 µF.
