WIPO Patent Application WO/2023/243315
Kind Code:
A1
Abstract:
One aspect of a rotating electric machine according to the present invention comprises: a rotor; a stator; a housing including a first accommodating portion accommodating the rotor and the stator therein; and a hollow tubular member extending in an axial direction and accommodated inside the first accommodating portion. A stator core includes a stator core body and at least one fixation portion protruding radially outward from an outer peripheral face of the stator core body. The at least one fixation portion comprises an upper fixation portion positioned on the upper side of a central shaft in the vertical direction. The upper fixation portion is positioned on one side in a circumferential direction of the tubular member. The tubular member includes a first opening that opens inside the first accommodating portion and is positioned on the upper side of the stator core body in the vertical direction. At least a part of the tubular member, when seen in the vertical direction, overlaps a tooth positioned on an uppermost side in the vertical direction among a plurality of teeth. An inner face of the first accommodating portion includes an opposing portion opposing a radially outer side of the upper fixation portion via a gap. The first opening opens toward the opposing portion.
