Abstract:
1. A motor including: a stator provided with a distributed winding coil formed of a flat wire and a stator core; and a rotor provided with a central shaft, wherein the coil has a coil end part at one end bent toward the rotor side with respect to an in-slot wire part of the stator core, the one-end coil end part is located closer to an axis of the rotor than an inner peripheral surface of the stator core, and the one-end coil end part and a coil end part at the other end are each formed of a plurality of portions of the flat wire wound flatwise in overlapping relation, the one-end coil end part is formed in a concentric semi-circle shape, and the other-end coil end part is formed in a concentric semi-circle shape, a pair of terminals protrude outward from both sides of the other-end coil end part formed in the concentric semi-circle shape, and the terminals are overlapped on a terminal of an adjacent coil in an axial direction of the rotor, in the one-end coil end part, the portions of the flat wire placed in adjacent slots are overlapped one on another in a circumferential direction of the rotor, and in the other-end coil end part, the portions of the flat wire placed in adjacent slots are overlapped one on another in an axial direction of the rotor.
