An electric motor (10) drives a compressor (40) of a heat pump system in a laundry machine, e.g., a tumble dryer. The electric motor (10) is an asynchronous motor. The electric motor (10) includes a main coil (12) and an auxiliary coil (14). A control unit (22, 24, 26) is dedicated to the electric motor (10). The control unit includes capacitance circuitry including at least one capacitor (22, 24). The main coil (12) is parallel-connected to a series including the auxiliary coil (14) and the at least one capacitor (22, 24). The main coil (12) is connected or connectable to a power source (34). The capacity of the capacitance circuitry is variable depending directly or indirectly on parameters including, e.g., the actual torque of the electric motor (10). Further, the present invention relates to a method for operating the laundry machine with the heat pump system (10).
A laundry machine with at least one heat pump system comprising at least one compressor and at least an electric motor for driving the compressor, wherein:
A method for operating a laundry machine with at least one heat pump system comprising at least one compressor and at least an electric motor for driving the compressor, wherein the electric motor is an asynchronous motor including a main coil and an auxiliary coil, and capacitance circuitry is provided comprising at least one capacitor between the main coil and the auxiliary coil, the method comprising:
