Motor Start Capacitors

The capacitor start motor is the most widely used among various types of single phase motors. Connecting a capacitor in series with the starting winding achieves the starting torque with a lower starting current leading to a torque that is higher than other types of single phase motors like the shaded pole type. Thus, for machines which have a heavy starting duty, these capacitors are ideal. A capacitor – start motor comes with a centrifugal switch which automatically disconnects the auxiliary winding when motor attains a pre – determined speed. Hence, it works only with the help of the main winding.

A capacitor connected to a motor develops a higher voltage across it than that applied to the motor. Hence, designing the Motor start capacitor is more important.

“YASHA” motor-start capacitors are robustly built as compared to general purpose capacitors available in market as well as they are designed for HEAVY DUTY usage. They are built for motors where Voltage across terminals goes beyond 275 Volts and surge voltage can go up to 350 Volts. Of course at their rated voltage of 230 V and 275 V surge, they gives an even longer life span.
