Document Type and Number:
WIPO Patent Application WO/2020/148869
Kind Code:
A1
Abstract:
Provided are a rotating electric machine stator, the coil occupancy rate of which can be improved and the productivity of which can be improved and a method for manufacturing the rotating electric machine stator. The rotating electric machine stator (1) according to this invention is provided with: a core (20) having an annular connection body in which a plurality of yokes (21) are annularly connected at intervals and a plurality of tooth portions (22); and a bobbin (40) attached to each of the tooth portions (22) in order that a conductor wire forming a coil (30) is wound therearound. The tooth portions (22) are each formed as a member separated from the yokes (21) and can be held by the annular connection body in a state of facing in a direction along the central axis of the annular connection body.
