Title:
STATOR AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/043263
Kind Code:
A1
Abstract:
The present invention pertains to a bottomed cylindrical stator (2) that accommodates an armature (12) secured to a rotary shaft (11). This stator is equipped with a bottomed cylindrical main yoke (21), a belt-like auxiliary yoke (22) arranged on the outer circumferential wall surface or the inner circumferential wall surface of this main yoke, and field magnets (23) arranged in the interior of the main yoke. The auxiliary yoke is arranged along the circumferential direction of the outer circumferential wall surface or the inner circumferential wall surface of the main yoke. One end of the auxiliary yoke has formed thereon at least one protrusion (22B), and the other end of the auxiliary yoke has formed thereon at least one recess (22C) that opposes the protrusion in the circumferential direction and engages the protrusion, at the inner circumferential wall surface or the outer circumferential wall surface of the main yoke. Thus, when the auxiliary yoke is attached to the main yoke the effect of this attachment on the main yoke can be reduced.
