Zusammenfassung:According to one aspect of the present invention, a rotor includes: a rotor core configured to rotate with a shaft; and a plurality of permanent magnets inserted into the rotor core. The rotor core includes: a ring-shaped support unit; and a plurality of rotor poles arranged to be spaced apart from each other at an outer side of the ring-shaped support unit in a circumferential direction and connected to the ring-shaped support unit. The plurality of permanent magnets are inserted into between the plurality of rotor poles. A groove is formed at both sides of the rotor poles coming in contact with the permanent magnets. 본 발명의 일 측면에 따르면, 샤프트와 함께 회전하도록 구성되는 로터코어; 및 상기 로터코어에 매입되는 복수의 영구자석을 포함하고, 상기 로터코어는, 환형지지부; 및 상기 환형지지부의 외측에 원주방향으로 서로 이격되게 배열되고, 상기 환형지지부와 연결되는 복수의 회전자 폴을 포함하고, 상기 복수의 회전자 폴 사이에는 상기 복수의 영구자석이 삽입되고, 상기 영구자석에 접촉되는 상기 회전자 폴의 양측면에 홈이 형성되는, 로터가 제공될 수 있다.
