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 control apparatus includes an operation control unit; a first torque command value setting unit that sets a required torque command value; a second torque command value setting unit that sets a vehicle-stop torque command value; and a waveform setting unit that sets a torque waveform. The operation control unit controls the output torque of the rotary electric machine along the torque waveform when changing the output torque of the rotary electric machine. The waveform setting unit utilizes a first torque waveform and subsequently utilizes a second torque waveform as the torque waveform, the first torque waveform being capable of attenuating a vibration of the vehicle in a pitch direction, the second torque waveform being capable of suppressing a vibration in a power transmission member provided in a power transmission system for transmitting a torque of the rotary is electric machine to wheels.

Abstract: This vehicle comprises a first dynamo-electric machine that imparts torque to a first drive wheel, a second dynamo-electric machine that applies torque to a second drive wheel, a rotation speed sensor that acquires a first rotation speed of the first drive wheel, a rotation speed sensor that acquires a second rotation speed of the second drive wheel, and a control device. The control device includes a basic setting unit that sets a basic rotation speed, a differential setting unit that sets a differential rotation speed, and an action control unit that controls the operation of the first dynamo-electric machine and the second dynamo-electric machine so that an average value of the first rotation speed and the second rotation speed becomes the basic rotation speed, and a difference between the first rotation speed and the second rotation speed reaches the differential rotation speed.

Abstract: A control device for a vehicle includes an operation controller that controls operations of a rotating electric machine mounted to the vehicle, a first torque detector that detects a traveling torque which is a braking/driving torque to be output from the rotating electric machine when the vehicle is traveling, a second torque detector that detects a standstill torque which is a braking/driving torque to be output from the rotating electric machine upon the vehicle coming to a stop, and a waveform setter that sets a stop waveform which is a waveform indicating a time variation in the braking/driving torque output from the rotating electric machine from the traveling torque to the standstill torque. The operation controller performs a stop process that is a process to bring the vehicle to a stop while changing the braking/driving torque output from the rotating electric machine in accordance with the stop waveform.

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.
