Abstract

본 발명은 영구자석 동기모터의 회전자를 개시한다.The present invention discloses a rotor of a permanent magnet synchronous motor.

본 발명은 몸체 적층판이 여러장 적층되어 자기장의 통로가 형성되도록 구성되는 몸체 블록과; 자극면 적층판이 여러장 적측되어 구성되고, 몸체 블록의 반경방향으로 서로 일정 거리 떨어져 자석 스페이스들과 연결 스페이스들이 각각 형성되도록 장착되는 자극면 블록들과; 연결 스페이스들에 자기장의 흐름이 차단되도록 축 방향으로 대응되어 설치되며, 자석들의 측면이 지지되도록 그 양쪽측면에 지지면이 각각 형성되는 스페이서들과; 자극면 블록들의 바깥둘레에 씌워지는 원통형의 쉘을 포함한다.The present invention includes a body block configured to stack a plurality of body laminates to form passages of a magnetic field; A magnetic pole surface block comprising a plurality of magnetic pole surface laminates and mounted to form magnetic spaces and connection spaces apart from each other in a radial direction of the body block, respectively; Spacers correspondingly installed in the axial direction to block the flow of the magnetic field in the connection spaces, and supporting surfaces formed on both sides of the magnets to support the sides of the magnets; It comprises a cylindrical shell overlying the outer circumference of the magnetic pole block.

따라서, 몸체 블록과 자극면 블록들이 분할되어 스페이서들에 의해 서로 결합됨으로써, 불필요한 자기손실이 방지되어 제품의 효율이 현저히 향상되는 것이다.Therefore, the body block and the magnetic pole block are divided and bonded to each other by the spacers, thereby preventing unnecessary magnetic loss, thereby significantly improving the efficiency of the product.

또한, 몸체 블록과 자극면 블록이 분할되어 자석들의 조립공정이 용이하게 수행됨으로써, 생산설비 비용이 크게 감소되어 제품의 생산비용이 감소되는 것이다.In addition, since the body block and the magnetic pole surface block is divided to facilitate the assembly process of the magnets, the cost of the production equipment is greatly reduced and the production cost of the product is reduced.
