Abstract: An interior permanent magnet motor includes a stator provided with a plurality of slots and a rotor rotatably disposed inside the stator. A plurality of permanent magnets of the same polarity are disposed at equal intervals in a circumferential direction inside the rotor. A plurality of flux bathers are provided on left and right sides of one end of each of the plurality of permanent magnets adjacent to an outer circumferential surface of the rotor. A ratio of a number of slots of the stator to a number of magnetic poles of the rotor is 3:2 or 3:4. The number of permanent magnets provided in the rotor is ½ of the number of magnetic poles of the rotor.
