Abstract
An inductive detection type rotary encoder of the present invention includes: first and second transmission windings in a stator; first and second reception windings within first and second regions, respectively; and first and second magnetic flux coupling bodies within third and fourth regions, respectively, in a rotor. The second, first, third, and fourth regions are sequentially disposed in an axial direction. The shortest distance between the first transmission winding and the first magnetic flux coupling body is shorter than those between the second transmission winding and the first magnetic flux coupling body and between the first transmission winding and the second magnetic flux coupling body. The shortest distance between the second transmission winding and the second magnetic flux coupling body is shorter than those between the first transmission winding and the second magnetic flux coupling body and between the second transmission winding and the first magnetic flux coupling body.
