Abstract

The invention relates to an electric motor for driving a compressor, in particular a compressor for use in a heat pump system in a tumble dryer. The electric motor (10) is an asynchronous motor. The electric motor (10) includes a main coil (12) and a secondary coil (14). The control units (22, 24, 26) are dedicated to the electric motors (10). The control unit includes at least one capacitor (22, 24). The primary coil (12) is connected in parallel with a series circuit including a secondary coil (14) and at least one capacitor (22, 24). The main coil (12) is connected or connectable to a power supply (34). The capacitance value of at least one capacitor (22, 24) changes directly or indirectly as a function of the actual torque of the electric motor (10). Furthermore, the invention relates to a method of operating a laundry machine with a heat pump system (10).

Description

technical field [0001] The invention relates to a laundry machine with at least one heat pump system comprising at least one compressor and at least one electric motor driving the compressor. In particular, the laundry machine is a tumble dryer or a washing machine having a drying function, however the present invention is applicable to a washing machine having a heat pump system for heating wash water. Further, the present invention relates to an operating method of a laundry machine having a heat pump system. Background technique [0002] It is possible to effectively save energy in the laundry machine by using heat pump technology. For example, a tumble dryer with a heat pump system includes a closed air flow circuit and a closed refrigerant circuit. The air flow circuit and the refrigerant circuit are coupled via at least two heat exchangers. [0003] In the refrigerant circuit, the refrigerant is compressed and heated by the compressor. The compressor is driven by a...
