Abstract: A motor unit includes a stator including a coil formed from a wound winding that is configured by a conductive member including an insulating covering layer on the surface of the conductive member, a rotor that rotates under the influence of a rotating magnetic field generated by the stator, and a centerpiece that supports the stator and is formed with a centerpiece-side winding insertion hole through which the winding is inserted. The motor unit also includes a circuit device and a potting section. The potting section is formed using potting material, and seals a gap formed between the centerpiece-side winding insertion hole and the winding by achieving a state in which a portion of the potting section is closely adhered to the covering layer of the winding.

Abstract: A motor includes a rotor and a stator including a stator core and a winding including a first extension extending with respect to the stator core toward one side in a rotation-axis direction of the rotor, a second extension extending toward a rotation-radial direction outside of the rotor from an end of the first extension on the one side in the rotation-axis direction, and a third extension extending toward the one side in the rotation-axis direction from an end at the rotor rotation-radial direction outside of the second extension, and connected to a circuit device, and the winding forming a coil around the stator core, and such that an inner bent portion at a boundary between the first and second extensions is disposed at the one side in the rotation-axis direction with respect to an outer bent portion at a boundary between the second and third extensions.
