Q. Explain working of Capacitor motors?
Capacitor motors have a capacitor in series with the auxiliary winding and come in three varieties: capacitor start, two-value capacitor, and permanent-split capacitor. As their names imply, the first two use a centrifugal switch or relay to open the circuit or reduce the size of the starting capacitor when the motor comes up to speed. A two-value-capacitor motor, with one value for starting and one for running, can be designed for optimum starting and running performance; the starting capacitor is disconnected after the motor starts. The relevant schematic diagrams and torque-speed characteristics are shown in Figures. Motors in which the auxiliary winding and the capacitor are not cut out during the normal running conditions operate, in effect, as unbalanced two-phase induction motors.
