    摘要: An SR motor includes a stator having a plurality of salient poles and a rotor having another plurality of salient poles. Windings are wound around the plurality of salient poles and magnetic fields are generated in the plurality of salient poles. The number of salient poles of the rotor is determined depending upon a number of the salient poles of the stator. A supply mode for supplying power from a power supply to the windings, a reflux mode for setting both terminals of the windings to an identical potential, and a regenerative mode for recovering an electromotive force generated in the windings into the power supply are executed as the rotor rotates. The reflux mode and the regenerative mode are preferably repeated in a period during which the inductance of the windings is reduced as the rotor rotates.

    摘要: An axial gap motor may benefit from a reduction of axial force on the rotor, which may reduce load on the rotor and bearings and reduce the vibration on the surface of the rotor. An air gap is positioned on the stator facing the rotor, and an auxiliary yoke is positioned facing the air gap on the other side of the rotor. Magnetic flux circulates from the rotor and the axial force α is applied to the rotor when the magnetic flux passes by the air gap surface on the stator side of the rotor. Axial force β is applied to the rotor when the magnetic flux passes by the air gap surface on the auxiliary yoke side of the rotor. Axial force β is opposite, or reverse, of axial force α and reduces axial force α so axial force α reduces the load on the rotor and bearings.

    摘要: A drive apparatus basically comprises left and right drive units each including at least a reduction gear, an electric motor without a permanent magnet, and a brake disc. Each of the left and right drive units is housed substantially within a rim of each of rear wheels which are driven wheels. A 4WD control unit is configured to control a pair of inverters to separately drive the electric motors when a vehicle speed is in a range between a standing start speed and a prescribed vehicle speed, and to stop driving the electric motors when the vehicle speed is equal to or greater than the prescribed vehicle speed to place the rear wheels in a driven state. Accordingly, a friction loss due to a cogging torque encountered in a conventional permanent magnet-type motor is eliminated, and a lightweight drive apparatus is obtained. Fuel efficiently is accordingly improved.
