Motor Run Capacitors

Single phase induction motors are not self rotating due to the lack of synchronously rotating magnetic field. At this juncture the Motor Run capacitor comes in picture. The main purpose of these capacitors is to generate an effective rotary field in single phase motors with two or three stator windings to allow them to be operated on a single phase supply.

The capacitors, in this case, remain in circuit during the whole running period of the motor. They are, therefore, ideally suited for single phase motors for use in pumps, fans, air conditioners, washing machines, refrigeration systems etc.

By employing the auxiliary winding for power output, a better utilization of the single phase motor is obtained, which is approximately 90 % of the output of the similar rating three phase motor.

“YASHA” motor-run 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 to 380 Volts. Of course at their rated voltage of 230 V and 440 V surge, they gives an even longer life span.
