Abstract: A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated. The information acquisition unit acquires information on a state of the vehicle. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.

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: An electric current sensor includes a core having a coupling portion formed by bending a part of a plate member, and one end portion and the other end portion of the plate member are disposed to oppose to each other through a constant magnetic gap on a side opposite from the coupling portion. The core has: a first tapered portion in which a width of the plate member continuously decreases from one end of the coupling portion adjacent to the one end portion to a distal end of the one end portion; and a second tapered portion in which the width of the plate member continuously decreases from an other end of the coupling portion adjacent to the other end portion to a distal end of the other end portion.

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.
