Embedded Permanent Magnet Type Electric Motor, Compressor, And Refrigeration Air Conditioning Device
Abstract: In this embedded permanent magnet type electric motor (1) multiple slits (81a 81b) are formed between the rotor outer circumferential surface (25) of a rotor (5) and the radial direction outer insertion hole surface (55) of each magnet insertion hole (21). The multiple slits (81a 81b) are formed so as to satisfy the relationship of 0.35=Ss/Si=0.5 wherein Ss represents the total area of the multiple slits (81a 81b) per one magnetic pole and Si represents the radial direction outer surface area of one corresponding magnetic insertion hole (21) of a rotor core (11).
