Permanent Magnet Embedded Electrical Motor, Compressor And Refrigerating Air Conditioning Device
Abstract: ThiS permanent magnet embedded electrical motor (1) is provided with a stator (3) and a rotor (5) arranged rotatably facing the stator (3). The rotor (5) has a rotor core (11) in which are formed a plurality of magnet insertion holes (21) for insertion of respectively corresponding permanent magnets (19). The plurality of permanent magnets (19) and the plurality of magnet insertion holes (21) are formed to arcuate shape oriented so as to be convex towards the center of the rotor (5) and where the shortest distance between neighboring magnet insertion holes (21) is denoted as the shortest interpolar distance (L) the ratio of the shortest interpolar distance (L) with respect of the outside diameter (D) of the rotor (5) is 0.035 ? L/D ? 0.045.
