Electric Motor Capacitors
A motor capacitor is a device that boosts the current to an electric motor. There are few types of capacitors mainly which serves different purposes like run capacitors, start capacitors and dual capacitors.
Run Capacitors: These capacitors are heavy duty devices, designed for continuous duty; they are also energized for the entire time till the motor is running. Run capacitors are rated in a range of 3-70 microfarads (mfd), with voltage classifications of 370 V to 440 V. single phase electric motors need a capacitor to energize a second phase winding. If a wrong run capacitor is installed the motor will cause the motor to become noisy, increase energy consumption, cause performance to drop, and start overheating.
Start Capacitors: A Start capacitor is installed to increase the motors starting torque and allow a motor to be cycled on and off rapidly. The start capacitors have ratings above 70 microfarads (mfd), with three major voltage classifications; 125V, 250V and 330V. a start capacitor stays energized long enough to rapidly bring the motor to3/4 of full speed and is then taken out of the circuit, by a centrifugal switch that releases when rotating around that speed.
