Document Type and Number:
WIPO Patent Application WO/2023/162257
Kind Code:
A1
Abstract:
This stator comprises: a stator iron core (11) including a back yoke (13) that is mounted around a shaft and surrounds a rotor (30), and a plurality of teeth (14) that are mounted at intervals in a circumferential direction of the shaft and attached to the back yoke (13); and a coil (12) wound around each tooth (14). Each of the teeth (14) has an inner peripheral surface facing the rotor (30), and includes a tip portion (14a) protruding forward and backward in a rotating direction of the rotor (30), and a base portion (14b) facing the back yoke (13). The inner peripheral surface (14c) includes a first region (14d), and a second region (14e). An average interval between the second region (14e) and an outermost trajectory of the rotor (30) is greater than an average interval between the first region (14d) and the outermost trajectory of the rotor (30).
