摘要：
A control system for a compressor motor used with an air conditioning unit is disclosed. A current for generating a non-rotating magnetic field is supplied to the compressor motor to preheat a compressor. A current for generating a rotating magnetic field is also supplied to the compressor motor together with the current for generating a non-rotating magnetic field to heat the compressor. The heat pump using this control system is thus capable of transmitting sufficient heat energy immediately after start of the operation of the heat pump.
