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.
Claims6
In a compressor motor provided with an outer lamination and an inner lamination, a magnet fixed structure for a compressor motor, comprising:
- a cylindrical magnet paddle disposed between the outer and inner laminations having a plurality of magnet insertion holes formed alone a circumference thereof, wherein a projected inner and outer circular arcs of each magnet insertion hole have a different length, the inner circular arc being measured alone an inner surface of the cylindrical magnet paddle and the outer circular arc being measured along an outer surface of the cylindrical magnet paddle;
- a plurality of magnets inserted into the magnet insertion holes;
- and
- a magnet fixing ring fixed to the inner surface of the magnet paddle if the projected inner circular arc is longer than the projected outer circular arc and fixed to the outer surface of the magnet paddle, which has a) if the projected outer circular arc is longer than the projected inner circular arc of the magnet insertion hole.
