The present invention relates to a compressor motor (M) electronic control circuit (1) used in cooling devices, and the control circuit (1) comprises a power line (2) providing the energy that is received from the AC power source to be transmitted, an auxiliary winding (3) forming a torque at the start when voltage is applied to the compressor motor (M) from the AC power source, a main winding (4) forming the magnetic field that is required for constant operation, a capacitor (5) providing power factor correction by the auxiliary and the main windings (3, 4) and the reactive power being compensated, and a relay (6) having a switching contact (7) that moves when energy is applied thereon and the applied energy is cut off, thus, provides current transmission between the desired points, a common contact (8) whereto the fixed end of the switching contact (7) is connected, a first contact (9) remaining closed in the deenergized state and a second contact (10) remaining open in the deenergized state. |
