摘要 |
A high-permeability core has four legs of a quadrangular prism shape. An exciting coil has a first winding that is wound on two adjacent legs of the core, and a second winding connected to the first winding and wound on the other two adjacent legs in the direction opposite to the winding direction of the first winding. A detecting coil has a structure similar to that of the exciting coil, and oriented orthogonally thereto. The sensor is disposed adjacent to a rotary shaft such that a long side of each winding of the exciting coil is parallel to the axial direction of the rotary shaft. The core is-produced by forming a cruciform groove in a rectangular parallelepiped core block from one face.
