Abstract:
1. A motor including: a stator including a distributed winding coil formed of a flat conductor wire and a stator core formed with slots between teeth; and a rotor having a central axis, wherein the slots are sequentially arranged by group blocks each including a U-phase first slot, a U-phase second slot, a V-phase first slot, a V-phase second slot, a W-phase first slot, and a W-phase second slot, a second group block being formed adjacent to a first group block, and the flat conductor wire in a U-phase first slot of the first group block and the flat conductor wire in a U-phase second slot of the second group block form a first loop, the flat conductor wire in a U-phase second slot of the first group block and the flat conductor wire in a U-phase first slot of the second group block form a second loop, the second loop is placed inside the first loop, a coil end portion at one end of the second loop and a coil end portion at one end of the first loop are bent toward the rotor side with respect to in-slot conductor portions in the stator core, and the coil end portion at the one end of the second loop and the coil end portion at the one end of the first loop are located further toward the axis of the rotor than an inner peripheral surface of the stator core, the first loop and the second loop are each formed as a base unit including a predetermined number of flat conductor wires bent at the same time.
