Document Type and Number:
WIPO Patent Application WO/2021/166976
Kind Code:
A1
Abstract:
The present invention provides stator split bodies which each enable iron loss to be reduced more than conventional products and which facilitate dimension accuracy control. Stator split bodies (22) are each disposed in the circumferential direction in a split manner, a stator (20) to which a compression force is applied radially inward from a case (40) in a fitted state of being fitted to the inside of the case (40). The stator split bodies (22) have: split cores (26) that each have a yoke and teeth and that are each obtained by splitting, in the circumferential direction, a stator core (24); coils (28) into which the teeth are inserted and which are disposed in a non-contact state with respect to the split cores (26); and mold resin parts 30 formed with the coils (28) being embedded therein. The mold resin parts (30) each receive a compression force in the circumferential direction in the fitted state.
