Title:
AXIAL GAP ROTARY ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2018/142441
Kind Code:
A1
Abstract:
A conventional axial gap rotary electric machine has a problem in that after the rotary electric machine is assembled, an air gap between a rotor and a stator cannot be visually observed, and hence it cannot be determined whether the air gap is defective after the assembly, which leads to an increase in the failure rate. In order to solve the problem, the axial gap rotary electric machine according to the present invention includes: a rotor which rotates about a main shaft; a stator which is disposed to be opposed to the rotor in a main shaft direction; a housing which fixes the stator; and a bracket which is coupled to the housing to hold a bearing and to which the rotor is rotatably held, and the axial gap rotary electric machine has a configuration in which the rotor and the stator are arranged inside the housing and the housing has a through hole located on a radially extending line of an air gap between the rotor and the stator.
