Claims (1)
端部を前記受動軸に同心に固定された中空軸と、
高透磁率軟磁性材からなり前記中空軸の外周上に
固着された歪検出層と、前記受動軸を非磁性ベア
リングを介して回転自在に支承する軸受と、前記
歪検出層の周囲に配設され前記歪検出層の前記外
力に対応した歪による透磁率変化を検出する検出
コイルを備えてなるトルク検出器。 a passive shaft that receives an external force; a hollow shaft that surrounds the passive shaft and has both ends concentrically fixed to the passive shaft;
A strain detection layer made of a high magnetic permeability soft magnetic material and fixed on the outer periphery of the hollow shaft, a bearing rotatably supporting the passive shaft via a non-magnetic bearing, and a strain detection layer disposed around the strain detection layer. A torque detector comprising a detection coil for detecting a change in magnetic permeability due to strain in the strain detection layer corresponding to the external force.
