Rotary motor

Abstract

The present invention is a rotary motor comprising a rotor having an axis, a stator surrounding the rotor, a bearing of the axis, and a housing. The housing has a bearing bracket for supporting the bearing and receiving the rotor and stator. The bearing bracket has a wall and a plurality of reinforcement portions disposed at the wall. The wall has a first hole and a second hole into which the bearing is inserted, an inner periphery for supporting the bearing and an outer periphery. The second hole is located radially outward of the first hole with respect to the central axis, and penetrates the wall in the axial direction of the central axis.. Each reinforcement portion has a first end at an outer side in the radial direction and a second end at an inner side in the radial direction, extends along a direction vertical to the radial direction of the central axis, and protrudes along an axial direction of the central axis. The second end is located at a side closer to the second hole relative to a straight line connected to the first end and the central axis.
