Motor Run Capacitors

Motor run capacitors, beside providing automatic starting, increase the full load power of the motor. The voltage appearing across the capacitor is about 1.5-2 times the mains voltage and this voltage decreases with increase of the motor load.

List  Details  [1]   Motor Run Capacitors Single phase AC motors and capacitors Single phase AC motors (induction motors) are used in various domestic and industrial applications such as fans, washing machines, Air conditioner, Compressor motors, Refrigeration and chilling plant motors etc. Based on Motor starting torque & motor output characteristics motor manufacturers decide the capacitor rating to be used. Motor Run capacitors Motor run capacitors, beside providing automatic starting, increase the full load power of the motor. The voltage appearing across the capacitor is about 1.5-2 times the mains voltage and this voltage decreases with increase of the motor load. The rating of the capacitor is usually decided by the motor manufacturer considering starting torque and output characteristics of the motor as the torque and the output power of the motor depends upon the value of capacitance. Specification : These Capacitors are manufactured by using Metallised Polypropylene and encapsulated with polyurethene resin available both in aluminium & plastic cans. These capacitors are of Self Healing type with very low Dissipation Factor , High insulation resistance and longer life. •Type:Self Healing MPP Type •Conforming to IS 2993/IEC60252 for Motor Run capacitors. •Range :10 uF to 72 uF •Tolerance :+/- 5 % •Rated Voltage:230V / 415V / 440 V •Temperature Range:- 40 C to 85 C •Voltage Test a) Between Terminals :2 x Rated Voltage AC b) Between Body and Terminals:3 KV AC-3 •Dissipation Factor :2 x 10-3 (Tan Delta)   Motor Run Capacitors Single phase AC motors and capacitors Single phase AC motors (induction motors) are used in various domestic and industrial applications such as fans, washing machines, Air conditioner, Compressor motors, Refrigeration and chilling plant motors etc. Based on Motor starting torque & motor output characteristics motor manufacturers decide the capacitor rating to be used.
