Abstract
A motor includes a shaft that extends in an axial direction, a rotor including a field magnet, a stator, a resolver positioned farther toward one side of the motor in the axial direction than the rotor and the stator, and a shield including at least a portion is between the rotor and the resolver in the axial direction. The shield includes a bottom portion of which at least a portion is between the rotor and the resolver in the axial direction and which includes a through-hole through which the shaft passes, and a convex portion that extends from the bottom portion toward the other side in the axial direction. A front end portion of the convex portion is positioned farther toward an inner side of the motor in a radial direction than an outer circumferential portion of the field magnet when viewed in the axial direction.
