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.

Abstract: An inductive detection type rotary encoder comprises: a stator; and a rotor that is engaged with a rotation shaft to rotate along with the rotation shaft and faces the stator in an axial direction. The stator comprises at least two transmission windings and reception windings that are disposed from an inner peripheral side to an outer peripheral side, and the rotor comprises at least two magnetic flux coupling bodies that are respectively magnetic flux coupled with these at least two transmission windings and reception windings to configure angle detection tracks. Furthermore, inner peripheral side reception windings and outer peripheral side reception windings are connected in series, and are led out by lead-out wirings commonly used in the inner peripheral side reception windings and the outer peripheral side reception windings.
