Abstract
A resolver stator portion is attached to a resolver stator portion side attaching portion formed at a position facing to a resolver rotor portion via an elastic ring. Thus, it is possible to absorb a dimensional error of the resolver stator portion side attaching portion on the basis of an elastic deformation of the elastic ring even in the case that the dimensional error is generated in the resolver stator portion side attaching portion.
Claims18
An attaching structure of a resolver for attaching the resolver detecting a rotational angle of a motor to the motor, wherein
- a rotor of the resolver is attached to a shaft of the motor, and
- a stator of the resolver is attached to an attaching portion formed at a position facing to the rotor via a dimensional error absorbing means for absorbing a dimensional error of the attaching portion.
A dynamo-electric machine having a resolver detecting a rotational angle comprising:
- a rotatably provided shaft;
- a rotor of the resolver attached to the shaft;
- and
- a stator of the resolver attached to an attaching portion formed at a position facing to the rotor via a dimensional error absorbing means.
An attaching method of a resolver for attaching the resolver detecting a rotational angle of a motor to the motor, wherein
- a stator of the resolver is attached to an attaching portion formed at a position facing to a rotor of the resolver via a dimensional error absorbing means, and a dimensional error of the attaching portion is absorbed by the dimensional error absorbing means.
