The present invention relates to a motor structure including a controller, which simplifies the connection between a coil part and a circuit part and reduces the number of parts to simplify assembly and increase starting torque to increase performance of a motor. According to the present invention, the motor structure including a controller comprises a motor and a controller electrically connected to the motor to electrically control the motor. The motor comprises: a rotor installed on a fork formed on a tire rim; a plurality of fixed magnets installed in the rotor; a bracket installed in the rotor; a stator coupled to the outer circumferential surface of the bracket to wind 3-phase coils therearound; a bearing coupled to the inside of the bracket; a rotary shaft supported by the bearing; and a position sensor installed to be spaced apart from the stator at a predetermined interval to detect the effect of a current flowing in the wound coil. Accordingly, the 3-phase coils and the position sensor prevent changes to rectification timing in accordance with the current of the stator and adjusts a phase change in a position detection signal in accordance with an increase in load. Moreover, the motor structure comprises: the rotor having a permanent magnet installed therein to be disposed to have two pairs of poles; 3-phase coils connected in a star shape; and a plurality of position sensors connected to the 3-phase coils. Accordingly, provided is an effect of preventing, by a signal applied from the position sensors, that the rectification timing is changed in accordance with the effect of current flowing in a stator coil.

    본 발명은 코일부와 회로부의 연결을 단순화 및 부품의 수를 줄여 조립이 용이하고, 기동토크를 증가시켜 모터의 성능을 향상시킬 수 있도록 한 컨트롤러를 포함하는 모터구조에 관한 것으로, 터이어의 림에 형성된 포크에 설치되는 회전자와, 회전자 내측에 설치되는 복수의 고정자석과, 회전자 내측에 설치되는 브래킷과, 브래킷의 외주면에 결합되어 3상 코일이 권취되는 고정자와, 브래킷의 내측에 결합되는 베어링과, 베어링에 지지되는 회전축, 및 고정자에 일정한 간격을 두고 설치되어 권선된 코일로 유입되는 전류의 영향을 감지하는 위치센서로 이루어지는 모터와; 상기 모터를 전기적으로 컨트롤할 수 있도록 모터와 전기적으로 연결되는 컨트롤러;를 포함하되, 3상의 코일과 위치센서에 의해 고정자의 전류에 따른 정류시점이 이동되는 것을 방지하고, 부하의 증가에 따른 위치검출신호의 위상변화를 조정하는 것을 특징으로 하며, 두쌍의 극을 갖도록 배치되는 영구자석이 설치된 회전자와, 성형결성 된 3상 코일과, 3상 코일에 연결되게 위치센서를 복수로 설치하며, 위치센서에서 인가되는 신호를 에 의해 고정자 권선에 유입되는 전류의 영향에 의한 정류시점이 이동되는 것을 방지하는 효과가 있다.
