Abstract

　ギヤ付きモータ（１）の磁気式アブソリュートセンサ（５）は、２極マグネット（５１）とホール素子（５２（１）～５２（４））を備えている。２極マグネット（５１）は、中空ロータシャフト（３５）の中空部（３８）に固定されている。中空部（３８）の後端側からは、モータハウジング（２）の端板（２２）に取り付けたブラケット（５４）が同軸状態に挿入されている。ブラケット（５４）の円筒部分（５４ｄ）には、前側から２極マグネット（５１）が挿入された状態となっており、円筒部分（５４ｄ）の円形内周面には、９０度間隔でホール素子（５２（１）～５２（４））が配置され、これらは一定のギャップで２極マグネット（５１）の円形外周面に対峙している。磁気式アブソリュートセンサを組み込むためにモータ軸長を長くする必要がない。モータ駆動マグネットの磁束は中空ロータシャフト（３５）により遮断され、ホール素子に悪影響が及ばない。
