Start capacitors
Motor-Start-Capacitor A capacitor motor in which the capacitor is in the circuit only during the starting period; the capacitor and its auxiliary winding are disconnected automatically by a centrifugal switch or other device when the motor reaches a predetermined speed. Also known as capacitor motor. Start capacitors above 20 microfarads (µF) are always non-polarized Aluminum Electrolytic Capacitors with non solid electrolyte and therefore they are only applicable for the short motor starting time. Start capacitors briefly increase motor starting torque and allow a motor to be cycled on and off rapidly Start capacitors have ratings above 70 microfarads (µF), with four major voltage classifications: 125 V, 165V, 250 V, and 330 V.A start capacitor stays in the circuit long enough to rapidly bring the motor to 3/4 of full speed and is then taken out of the circuit, such as by a centrifugal switch that releases at that speed. The motor after that runs more efficiently with a run capacitor. 1)	AC Motor. 2)	High Torque need for start. Examples of motor capacitors are: a 35 µF/mfd, at 370 V, run capacitor, or an 88–108 µF/mfd at 250 V start capacitor.
