(b) The stator coil has coil end portions protruding outward from both end portions of the stator core in the direction of the axis CL. (c) In the direction of the axis CL, the length of the rotor core and the permanent magnets is longer than the length of the stator core, and the rotor core and the permanent magnets are arranged at positions including the stator core.
