| 简介 |
A rotor of an interior permanent magnet motor includes a rotor core having a plurality of magnet insertion holes, a shaft, a plurality of rare-earth magnets, and a pair of magnet fixing members. One surface of the magnet fixing member is provided with a plurality of pairs of tongue-like portions, and the tongue-like portions are inserted into the magnet insertion holes. On each of both sides in a rotary shaft direction, the rare-earth magnets have both end surfaces in a rotor circumferential direction sandwiched by a corresponding pair of tongue-like portions. An interval between the tongue-like portions includes, at a position separated from a base position, an interval that is smaller than the width of the rare-earth magnet in the rotor circumferential direction. |
