Abstract
Official abstract text for this publication.
A resolver can have a stator installed in a housing simply, without requiring a special jig. In the resolver including a housing and a stator core fixed in the housing, the stator core is fixed to the inside of the housing by rotating relative to the housing.
First claim
Opening claim text (preview).
What is claimed is: 1. A resolver comprising: a housing in an approximately cylindrical shape; a stator core in an approximately annular shape fixed to an inside of the housing; a rotor core arranged on an inside of the stator core; a concavity provided on an outside of the stator core; and an engaging portion that engages with the stator core provided on the inside of the housing, the engaging portion including: a circumferential direction contacting portion which protrudes inwards from the inside of the housing towards the stator core, the circumferential direction contacting portion contacting in a circumferential direction with a step portion of the concavity; and an axial direction contacting portion which protrudes inwards from the inside of the housing towards the stator core, the axial direction contacting portion contacting in an axial direction with an end surface of the stator core, wherein the stator core is fixed to the inside of the housing by rotating relative to the housing. 2. The resolver according to claim 1 , wherein the housing is formed by aluminum die-casting. 3. The resolver according to claim 1 , wherein a receiving portion that contacts with an end surface in an axial direction of the stator core is provided on the inside of the housing, and the stator core is held between the receiving portion and the axial direction contacting portion. 4. The resolver according to claim 1 , wherein a portion that contacts with the stator core of the axial direction contacting portion is inclined in a circumferential direction.
