摘要： An insulating bobbin to be mounted on a stator core has a tooth-endface facing portion that faces an endface portion, in an axial direction, of the tooth portion and a tooth-side-surface facing portion that faces a tooth side surface portion, in a circumferential direction, of the tooth portion; the tooth-side-surface facing portion has a first abutting area that abuts on the tooth side surface portion, a second abutting area that abuts on the tooth side surface portion at a more outer side in a radial direction than the first abutting area abuts thereon, and a middle inner wall surface portion that is situated between the first abutting area and the second abutting area and faces the tooth side surface portion via a space.

摘要： In a redundancy resolver device, winding groups of different systems are arranged at different positions in a circumferential direction of a stator core. The winding groups of each system include: an excitation winding group consisting of a plurality of excitation windings, and being connected to corresponding one of excitation circuits; a first output winding group; and a second output winding group. Each of the teeth has corresponding one of the excitation windings wound therearound. When two of the excitation windings belonging to different systems and being arranged side by side is the circumferential direction of the stator core are defined as a first end excitation winding and a second end excitation winding, respectively, the first end excitation winding and the second end excitation winding are applied with excitation signals to generate magnetic fluxes in the same direction of radial directions of the stator core.
