Magnet fixed structure for compressor motor
TLDR
In this article, a fixed structure for a compressor motor, which includes a cylindrical magnet paddle in which a plurality of magnet insertion holes are formed along a circumference thereof, and a magnet fixing ring or a varnish-type molding member for fixing the magnets, effectively fixes the magnets to the magnet paddle, for improving reliability and efficiency of the compressor motor.Abstract:
A magnet fixed structure for a compressor motor, which includes a cylindrical magnet paddle in which a plurality of magnet insertion holes are formed along a circumference thereof or a cylindrical magnet paddle alone, a plurality of magnets inserted into the magnet insertion holes of the magnet paddle or fixed to the magnet paddle, and a magnet fixing ring or a varnish-type molding member for fixing the magnets, effectively fixes the magnets to the magnet paddle, for thereby improving reliability and efficiency of the compressor motor as well as mass-productivity thereof.read more
