PROBLEM TO BE SOLVED: To uniformly magnetize magnets over all regions while making a polar array of the magnets uniform even when magnetizing the magnets installed in a rotor of a motor in a state of completing assembly of the motor provided in a compressor in a magnet magnetizing method for a compressor motor. SOLUTION: The compressor motor is provided with a stator, which is fixed to a frame and in which each coil is wound around in its inside, and a rotor that is freely rotatably provided inside the stator and in which a plurality of magnets are arranged on the outer peripheral side so as to have alternate polarities. The magnets are magnetized by applying magnetization power supply to each coil in a state of completing the assembly of the motor. The rotor is fixedly supported so as to prevent the rotor from being oscillated in a process of magnetizing the magnets. A magnetic-body member longer than a length of each magnet is inserted between the rotor and the stator. COPYRIGHT: (C)2008,JPO&INPIT
