Abstract
An electric motor is provided with a rotator and a stator 110 disposed on an outer diameter side of the rotator. The stator 110 includes a cylindrical stator iron core 50 provided with a plurality of teeth 62 radially projecting from an inner circumferential side of an annular yoke 61 toward a center, insulators 40 made of an insulation material disposed on both ends of the stator iron core 50 in an axial direction, and lead wire wound around the teeth 62 via the insulators 40. First grooves 31 to 39 disposed on an inner circumferential side of the insulator 40 and second grooves 51 to 59 disposed on an inner circumferential side of the stator iron core are formed to communicate with each other. A part of a connection line connecting the windings with each other is embedded in the first grooves and the second grooves.
