A permanent split-motor capacitor

Permanent split capacitor (OJSC) motor used in compressors for Air conditioning and refrigeration units. Its advantage over the capacitor-start motor as it is not needed centrifugal switch associated with its problems.

OJSC motor has run capacitor in series with the start winding. As a capacitor, and began winding remain in the circuit during launch and once the motor is up to speed. Engine torque enough for capillary and other self-adjustment system. No start capacitor or relay needs. OJSC motor mostly compressor motor. It is also used in refrigerator compressors. Very often through the 3 PS It is also available in 4 and 5 liter sizes (see Fig. 7-17).
