Claims (1)
密となるロータを有してなるステツピングモータ
において、上記磁束の疎密の距離と等しい距離分
離れた２つのセンサ部を有する磁気検知体を上記
ロータに対向させてモータ内に設けたことを特徴
とするステツピングモータ。 In a stepping motor comprising a stator having a plurality of poles and a rotor in which magnetic flux is alternately dense and dense, a magnetic sensing body having two sensor parts separated by a distance equal to the distance between the sparse and dense magnetic fluxes is attached to the rotor. A stepping motor characterized in that the stepping motor is provided within the motor so as to face the stepping motor.
