Title:
ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/228270
Kind Code:
A1
Abstract:
The present invention comprises a rotating shaft (12) supported by a bracket (42) via a bearing (20) so as to be capable of rotating freely and a brush (52) that is supported by a support section (51) provided to the rotating shaft and brought into contact with the bracket on the outer circumferential side of the bearing. The rotating shaft and the bracket conduct electricity via the support section and the brush. As a result of being configured so that the rotating shaft and the bracket conduct electricity on the outer circumferential side of the bearing via the support section and the brush, it is possible to suppress electric corrosion of the bearing and reduce the scattering of wear debris.
