  • Commercial compressor with electronic start device for the start of the electric motor
    Patent number: 10027258
    Abstract: A compressor for commercial refrigerators comprises an electric motor having a start winding (120) and a run winding (130), in which the input terminals of the start winding (120) and the run winding (130) are connected together and to the line voltage (L), and an electronic start device to supply the start winding (120) during a starting period. The electronic start device comprises a run condenser (40) having a first terminal connected to the output terminal from the start winding (120) and a second terminal connected to the output terminal from the run winding (130), and a start capacitor (45) having a first terminal connected to the output terminal of the start winding (120).
