MAGNETIZING JIG, MAGNETIZING METHOD USING THE JIG, AND METHOD OF ASSEMBLING ELECTRIC COMPRESSOR BY USING THE JIG AND THE MAGNETIZING METHOD

摘要

A method for assembling an electric compressor which contains a rotor having built-in magnets. The present invention offers a magnetizing method and an assembly method for implementing high reliability electric compressors at low manufacturing cost. Magnet (130) at pre-magnetization state is inserted into a plurality of slots (104) of magnetizing jig (100) made with a nonmagnetic material. After magnetizing the magnets, magnetizing jig (100) is coupled fitted to the rotor to have the magnets (130) transferred into magnet slots.
