Abstract (en)
[origin: EP3144533A1] A medium-frequency hermetically sealed refrigerant compressor capable of unloading during start, comprising: an electric connector (2), a front end socket (1), a rear end socket (6), a barrel (7), a medium-frequency motor (3) disposed in the barrel (7), a movable disc (4), a motion transmission sleeve (8), a main shaft (9), a clutch coil (10) and a clutch friction plate (11); the front and back ends of the barrel (7) are respectively connected to the front end socket (1) and the rear end socket (6); the barrel (7) has a stator disc (5) fixed therein cooperating with the movable disc (4); the movable disc (4) and the stator disc (5) are sleeved on one side of the main shaft (9), and the clutch friction plate (11) and the clutch coil (10) are sleeved on another side of the main shaft (9); the movable disc (4) and the clutch friction plate (11) are fixed on a side surface of the main shaft (9); the output shaft of the medium-frequency motor (3) is connected to the clutch coil (10) via the motion transmission sleeve (8); the electric connector (2) is fixed on the barrel (7); and the electric connector (2) is connected to the clutch coil (10). The compressor achieves a low current start, and reduces the impact against the on-board power supply.
