永磁铁埋入型电动机、压缩机以及制冷空调装置
摘要：
本发明提供永磁铁埋入型电动机、压缩机以及制冷空调装置。在永磁铁埋入型电动机(1)中，在转子(5)中的转子外周面(25)与磁铁插入孔(21)的径向外侧插入孔外形面(55)之间形成有多条狭缝(81a、81b)，在将针对每一个磁极的多条狭缝(81a、81b)的总面积设为Ss，将转子铁心(11)中的对应的一个磁铁插入孔(21)的径向外侧面积设为Si时，多条狭缝(81a、81b)形成为满足0.35≤Ss/Si≤0.5的关系。
摘要（英）：

In an interior permanent magnet motor, a plurality of slits are formed between a rotor outer peripheral surface of a rotor and a radially-outer insertion hole contour surface of a magnet insertion hole. Assuming that a total area of the plurality of slits per magnetic pole is represented by Ss, and an area of a region in a rotor core on a radially outer side with respect to the corresponding one magnet insertion hole is represented by Si, the plurality of slits are formed so as to satisfy a relationship of 0.35≦̸Ss/Si≦̸0.5.
