ABSTRACT:
A motor includes a fixed portion, a rotor, a balancing plate, and at least one sensor mounted on the fixed portion. The fixed portion includes a stator having at least one winding and a plurality of pole faces. The rotor includes an annular magnet facing the pole faces of the stator and a shaft rotatably extending through the fixed portion. The balancing plate is mounted on the fixed portion and includes at least two magnetically conductive faces that face at least one face of the annular magnet. The balancing plate presses against and thus precisely positions a body of the sensor so that the sensor and the annular magnet have a certain distance therebetween while providing a magnetically attracting balancing effect between the at least two magnetically conductive faces and the annular magnet.
