Document Type and Number:
WIPO Patent Application WO/2024/057881
Kind Code:
A1
Abstract:
Provided are: a stator that enables, with a simple configuration, winding disturbance of a coil to be suppressed; and a motor that uses the stator. This stator (4) comprises: a core (41) equipped with a plurality of magnetic pole parts extending in a radial direction cd; a plurality of insulators (45) corresponding to the plurality of magnetic pole parts (41c); and a ring (7, 8). The plurality of insulators (45) are each equipped with a connected part. The ring (7, 8) is equipped with a plurality of connecting parts. The connected parts of the plurality of insulators (45) and the plurality of connecting parts are connected to each other. Furthermore, one aspect of this motor (1) comprises: the stator (4); and a housing (5) that accommodates the stator (4). An inner circumferential surface (51a') of the housing (5) and an outer circumferential surface (71a) of the ring (7) are fixed. Another aspect of this motor (1) comprises: the stator (4); and a housing (5) that has a first tubular section (51a) and a second tubular section (51b) which accommodate the stator (4). An inner circumferential surface (51b') of the second tubular section (51b) and an outer circumferential surface (82c) of the ring (8) are fixed.
