Abstract

본 발명은 회전자의 위치를 검출하여 고정자에 전류를 순차적으로 흐르게 하는 위치검출 센서부를 하우징에 조립한후 고정자톱니에 고정시켜 위치검출용 영구자석이 불필요하도록한 무정류자 전동기에 관한 것으로, 홀센서(9)는 고정자(6)에 대하여 원주방향으로 상대위치에 위치하게 되므로 결국 홀센서(9)에서 검출된 신호는 고정자(6)에 대한 회전자(2)의 상대위치가 된다.The present invention relates to a no-commutator motor in which a position detecting sensor unit for detecting the position of a rotor and sequentially making current flow through the stator is assembled to a housing and then fixed to the stator teeth to make the position detecting permanent magnet unnecessary, The signal detected by the Hall sensor 9 becomes the relative position of the rotor 2 with respect to the stator 6 since the rotor 9 is located at the relative position with respect to the stator 6 in the circumferential direction.

그러나 종래 무정류자 전동기는 회전자(2)의 위치를 검출하는 홀센서(9)가 센서용 인쇄 회고기판(10)에 설치되어 지지부(13)에 의해 고정자(6)에 고정지지되어 있어 회전자(2)가 회전시 회전자(2)내측에 고정된 고정자(6)가 진동하여 센서용 인쇄회로기관(10)이 수명을 저하시키며, 상기 회전자위치 검출에 필요한 자속을 발생하는 별도의 위치검출용자석(5)을 회전자(2)의 끝단에 설치된 영구자석(4)에 체결시키므로서, 조립공정이 복잡하고 원가가 상승되며, 센서용 인쇄회로기판(10)과 공정자(6)사이에 납땜된 센서와이어(11)가 쉽게 단선되는 문제점이 있었다.However, in the conventional free rectifier motor, the hall sensor 9 for detecting the position of the rotor 2 is fixed to the stator 6 by the support portion 13 provided on the printed circuit board 10 for sensors, The stator 6 fixed to the inside of the rotor 2 vibrates when the rotor 2 rotates to reduce the service life of the sensor 10 for the sensor circuit and to generate a magnetic flux necessary for detecting the rotor position Since the detecting magnet 5 is fastened to the permanent magnet 4 provided at the end of the rotor 2, the assembly process is complicated and the cost is raised, There is a problem that the sensor wire 11 soldered between the electrodes is easily disconnected.

본 발명은 이와같은 종래 문제점을 해결하기 위하여 홀센서가 설치된 센서용 인쇄회로기판을 센서하우징에 체결시켜 고정자와 진동을 방지하기 위한 고정자톱니에 체결시키고, 센서용인쇄회로기판의 출력단자를 직접 콘넥터에 삽입되도록 하므로서, 조립시간 단축 및 원가를 절감할 수 있도록 한것으로 무정류자 전동기에 적용한다.In order to solve such a conventional problem, the present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a sensor circuit for a sensor, So that the assembling time can be shortened and the cost can be reduced. Therefore, the present invention is applied to a no-commutator motor.
