Abstract
A stator for an electric motor includes: a stator core that includes a plurality of teeth on which insulating portions are provided; and a coil formed by winding a wire around each of the teeth. A lead-in opening and a lead-out opening are formed in insulating portions provided on an outside diameter side of the stator core. The lead-in opening leads in a crossover wire of the coil routed to an outer peripheral side of the insulating portions to the side of the teeth. The lead-out opening leads out the crossover wire of the coil from the side of the teeth to the outer peripheral side of the insulating portions. The length from an axial end portion of the stator core on an insulating portion side to the lead-in opening is different from the length from the axial end portion to the lead-out opening.
