Abstract:
An electric motor includes a rotor and a stator. The stator includes a first stator core located on a first side in the axial direction, and a second stator core located on a second side. The minimum distance from a rotor core of the rotor to the first stator core in the radial direction is smaller than the minimum distance from the rotor core to the second stator core in the radial direction. Each tooth of the first stator core includes a tooth end portion. The tooth end portion includes a main body extending in the radial direction, and a first portion extending in the circumferential direction, and a second portion projecting from the first portion in the radial direction.
