Dc motor

Abstract

Abstract PURPOSE:To enable to compensate the phase delay of detecting the angle of a rotor at a high speed rotation time by securing a detector for detecting the rotating position of the rotor to a base material, and varying the securing position of the base material to a stator on the periphery of the same shaft as a rotational shaft of the rotor. CONSTITUTION:3 Detectors 4a-4c are, for example, secured to a base material 7. The rotating position of a rotor is detected by the detectors 4a-4c. The material 7 is composed variably at the securing position along the periphery of a stator 3 on the same shaft as the rotor. The securing position of the material 7 is formed variably, and the phase delay of detecting the angle at the high speed rotation time of the rotor is compensated. The direction of the current of the winding of the stator 3 is controlled in response to the outputs of the detectors 4a-4c.
