Abstract

본 발명은 코어레스 브러시레스 디씨(coreless brushless D.C.)(이하 코어레스형 비엘디씨(BLDS)라 한다)모터에 관한 것으로, 특히 스테이터용 코일을 로터의 상/하부에 대칭구조로 배치되는 것에 의해 코어/코어레스형의 장점은 극대화시키고 단점을 제거하여 로터의 축방향 진동을 억제하고 토크(torque)및 저소비전력화를 실현할 수 있는 더블 스테이터 방식의 코어레스형 BLDC 모터에 관한 것이다. 본 발명의 코어레스형 BLDC모터는 상하방향으로 다수의 자석이 균등하게 배치된 디스크형 로터와, 상기 로터의 중앙 부싱을 통해 결합된 회전축과, 상기 회전축을 회전가능하게 지지하는 상부/하부 케이스와, 각각 상기 상부/하부 케이스의 내주부에 설치되어 상기 로터에 서로 반대방향의 전자기력을 인가하기 위해 다수의 보빈레스 스테이터 코일을 구비한 상부/하부 스테이터로 구성되는 것을 특징으로 한다. 상기한 바와 같이 본 발명에 있어서는 로터를 중심으로 대칭구조의 자기회로가 형성되기 때문에 축방향의 진동이 적으며, 토크가 크고 소비전력이 적은 고효율의 모터가 제공될 수 있다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coreless brushless DC motor (hereinafter referred to as coreless brushless DC (BLDS)) motor. In particular, a stator coil is disposed symmetrically on the upper / / Coreless type, the present invention relates to a double-stator type coreless type BLDC motor capable of maximizing torque and eliminating disadvantages, thereby suppressing axial vibration of the rotor and realizing torque and low power consumption. A coreless type BLDC motor of the present invention comprises a disk-shaped rotor having a plurality of magnets uniformly arranged in a vertical direction, a rotary shaft coupled through a central bushing of the rotor, an upper / lower case rotatably supporting the rotary shaft, And an upper / lower stator disposed at an inner peripheral portion of the upper / lower case and having a plurality of bobbinless stator coils for applying electromagnetic force in opposite directions to the rotor. As described above, according to the present invention, since a magnetic circuit having a symmetrical structure is formed around the rotor, a highly efficient motor having less vibration in the axial direction, less torque, and lower power consumption can be provided.
