Abstract: An interior permanent magnet motor includes a stator comprising a hollow and a plurality of coils provided around the hollow; and a rotor rotatably disposed in the hollow of the stator and comprising a plurality of permanent magnets therein. Each of the plurality of permanent magnets of the rotor comprises a central permanent magnet; a pair of side permanent magnets provided at opposite ends of the central permanent magnet to be inclined toward an outer circumferential surface of the rotor; and a pair of bathers provided between the central permanent magnet and the pair of side permanent magnets, a thickness of each of the pair of bathers is equal to or greater than a thickness of the central permanent magnet. The thickness of the central permanent magnet is greater than a thickness of each of the pair of side permanent magnets.

Abstract: The BLDC motor includes a stator, and a rotor disposed inside of the stator and including a plurality of permanent magnet parts, each of the permanent magnet parts including first and second permanent magnets which are disposed to have an interval therebetween. The rotor includes a slot part including a first portion into which the first permanent magnet is inserted, a second portion into which the second permanent magnet is inserted, and a third portion connecting the first and second portions to each other. The first and second portions have one end portions which are spaced apart from each other by a first distance and other end portions which are spaced apart from each other by a second distance which is shorter than the first distance, and the third portion connects the other end portions of the first and second portions to each other.
