ROTARY ELECTRIC MACHINE AND DRIVE DEVICE

WIPO Patent Application WO/2024/005027

A1

The present invention comprises a rotor that is capable of rotating about a central axis, a stator that is disposed radially facing the rotor with a gap interposed therebetween, and a housing. The housing has a rotary electric machine accommodation unit that accommodates the rotor and the stator. The rotary electric machine accommodation unit has a peripheral wall part that radially surrounds the stator and a plurality of fixed parts to which the stator is fixed. The plurality of fixed parts include a first fixed part and a second fixed part that are adjacent to each other in the circumferential direction. The peripheral wall part is provided with: a first projection that surrounds the radial-direction outer side of the first fixed part, projects radially outward, and extends in the axial direction; a second projection that surrounds the radial-direction outer side of the second fixed part, projects radially outward, and extends in the axial direction; and a first side wall protrusion that projects radially outward to expand an internal space within the rotary electric machine accommodation unit radially outward and extends in the axial direction. The first side wall protrusion is positioned between the first projection and the second projection in the circumferential direction.
