Structure for mounting resolver

摘要

A structure for mounting a resolver in a housing, in which it is not necessary to use various different plates for forming the stator and accuracy of concentricity of the rotor and the stator is prevented from decreasing by a simple structure, are provided. The structure for mounting a resolver in a housing has a rotor and a stator arranged the outside of the rotor, in which the stator is mounted at an opening of the housing by clamps, projections are formed on an outer peripheral surface of the stator, protruding portions are formed on the clamps, and the stator is pressed to the housing by the clamps in a state in which the protruding portions are engaged with the concavities of the stator.

主权项

1. A structure for mounting a resolver in a housing, the structure comprising:
the housing having an opening for receiving the resolver, wherein a stepped portion is formed on an inner surface of the opening; an output shaft; the resolver disposed in the opening, the resolver comprising: a stator including a stator core having a ring-shaped yoke portion and a plurality of pole teeth extending inward from the yoke portion, wherein concavities are provided with the yoke portion, and a rotor attached to the output shaft and disposed inside the stator; a clamping member arranged on an end surface of the housing and having protruding portions, wherein an one end of the stator core is contacted with the stepped portion, an other end of the stator core is projected from the opening in an axial direction, and wherein the protruding portions of the clamping member are engaged with the concavities respectively so that the stator core is pressed in the axial direction by the clamping member.
