Abstract:
A motor includes a stator core, a first coil, and a second coil provided adjacent to the first coil in the radial direction. The first coil and the second coil do not coincide in position with each other as seen in the axial direction of the stator core. A first coil end portion of the first coil and a second coil end portion of the second coil respectively include a first facing portion and a second facing portion facing each other in the radial direction. The motor further includes an out-slot insulator interposed at least between the first facing portion and the second facing portion and provided so that at least a part of the first coil end portion and the second coil end portion is exposed.
