Claims (1)
光を検出する多素子の光電変換器とを配置し、前記整流
子面が回転した時セグメント間の絶縁部において反射光
が減少することを利用して回転角を検出する手段を組込
んだことを特長とするＤＣモータ。A light emitter and a multi-element photoelectric converter for detecting light reflected from the light emitter on the commutator face are arranged near the commutator face, and when the commutator face rotates, the reflected light is detected at the insulating part between the segments. A DC motor characterized by incorporating means for detecting a rotation angle by utilizing a decrease in the rotation angle.
