Title:
DYNAMO-ELECTRICAL MACHINE PROVIDED WITH BRUSH
Document Type and Number:
WIPO Patent Application WO/2019/180921
Kind Code:
A1
Abstract:
A heat-generating-component cooling channel and a bearing cooling channel are configured by attaching a channel cover to the rotor-unit side of a rear bracket/cooler. The bearing cooling channel is an arcuate channel extending along the peripheral direction of a rotary shaft. The region in which the bearing cooling channel is disposed in the axial direction of the rotary shaft is disposed so as to overlap at least a part of the region in which a rear bearing is disposed in the axial direction of the rotary shaft. The heat-generating-component cooling channel is disposed so as to overlap with at least a part of the region in which the heat-generating component is disposed, when viewed along the axial direction of the rotary shaft. A stator core is connected to the heat-generating-component cooling channel via the rear bracket/cooler.
