Problems solved by technology

[0008] However, during the magnetization of such conventional magnets, an excessively large rotating magnetic field is formed due to the high magnetization power applied to the coil, and the rotor is in the stator during the magnetization of the magnet due to the influence of such a rotating magnetic field. Rotate or shake freely, so there is a problem that the polarity arrangement of the magnet becomes uneven when magnetized
[0009] Furthermore, the above-mentioned magnet and the above-mentioned stator core are arranged to have approximately the same height and length as each other, but in this structure, there is a problem that the magnetic field formed in the stator during magnetization affects the upper and lower end portions of the magnet. Small, so part of magnetization is not completed on the upper end side and the lower end side of the magnet

Abstract

The present invention provides a method that can make the magnetic alignment of the magnets uniform even when the magnets provided on the rotor of the motor arranged in the compressor have been assembled, and can make the magnets uniform over the entire area. Magnet magnetization method for magnetized compressor motors. In the method for magnetizing a magnet of a compressor motor according to the present invention, the compressor motor includes: a stator fixed to a frame and having a coil wound therein; and a rotor rotatably provided inside the stator and having a A plurality of magnets are arranged in alternating polarity, and the above-mentioned magnets are magnetized by applying a magnetizing power supply to the above-mentioned coils in the state where the above-mentioned motor has been assembled. During the process of magnetizing the above-mentioned magnets, the above-mentioned rotor is fixedly supported to prevent It is free to move, and a magnetic member longer than the magnet is inserted between the rotor and the stator.

Description

technical field [0001] The present invention relates to a magnet magnetization method of a compressor motor, and more particularly, to a magnet magnetization method of a compressor motor capable of effectively magnetizing a magnet provided in a rotor of the compressor motor even when the motor is assembled. Background technique [0002] The compressor for compressing the refrigerant generally used in the refrigerating cycle of refrigerators or air conditioners forms an appearance through a sealed container, and a compression unit for compressing the refrigerant and a compressor for supplying refrigerant are arranged inside the sealed container. Compression of the refrigerant drives the motor. [0003] The above-mentioned motor includes: a stator fixed to a frame inside the hermetic container and around which a coil is wound; a rotor provided inside the stator and rotated by electric interaction with the above-mentioned stator; and a rotating shaft configured as a press It e...
