PURPOSE:To smoothly operate by detecting the magnetic flux of a field pole by a position detector, and flowing the armature current of an armature winding of other stage in response to the detected output. CONSTITUTION:A brushless motor 10 has a brushless motor body 15 which includes a flat cup-shaped housing 12, and a cover member 15 made of a disc- shaped soft steel plate fixedly press-fitted to the lower surface of the housing 12. A disc-shaped rotor 22 is supported to a rotational shaft 20, and the magnetic flux of the field pole of the rotor 22 is detected by position detectors H1, H2,.... The armature current flowed to the armature winding of other stage is decided in response to the output of the detector. |
