发明名称 ROTOR, PERMANENT-MAGNET-EMBEDDED MOTOR, AND COMPRESSOR
摘要 An end of each of slits of a rotor on a magnet insertion hole side has a triangular shape. A slit inner-side line of each of the slits includes an apex and a pair of side ends. An interval between each of the pair of side ends and the magnet insertion hole is larger than an interval between the apex and the magnet insertion hole, and an interval between the apex and the magnet insertion hole is larger than a plate thickness of each of steel plates forming a rotor core.

主权项 1. A rotor, comprising: a rotor core; and a plurality of permanent magnets, wherein the rotor core is formed by laminating a plurality of steel plates, wherein the rotor core has a plurality of magnet insertion holes, wherein at least one slit is formed between an outer peripheral surface of the core and an outer-side line of at least one of the magnet insertion holes, wherein an end of the slit on the magnet insertion hole side has a triangular shape as viewed in a plane having a rotation center line as a normal, and wherein the triangular shape projects toward the magnet insertion hole side.
