    • In a vehicular rotating electrical apparatus mounted in an electric vehicle or a hybrid electric vehicle, a rotating electrical machine apparatus in which a rotating electrical machine and an inverter unit to control the rotating electrical machine are integrated is miniaturized, and its torque characteristic and efficiency are improved. [Means for Resolution] Since an inverter unit 4 is cooled by cooling air forcibly formed by a cooling fan 28, the inverter unit 4 is efficiently cooled. Then, heat radiating fins 401a, 402a and 403a of heat sinks 401, 402 and 403 can be miniaturized, and consequently, the inverter unit 4 is miniaturized, and mountability of the inverter unit 4 to a rear bracket 19 is improved. Further, since the inverter unit 4 and a rotating electrical machine 2 are cooled by the cooling air formed by the cooling fan 28, the cooling medium of the inverter unit 4 is used also as the cooling medium (cooling air) of the rotating electrical machine 2, and a cooling structure is simplified.

Upon electrical excitation and rotation of the rotor (122) the starter-generator (100) supplies electrical power from each of the stator winding sets (128-1, 128-2) at different frequencies. Also, upon electrically exciting one or both of the stator winding sets (128-1, 128-2) with appropriate AC power, the rotor (122) will rotate and generate a starting torque.

    • A rotor assembly for a reluctance machine is disclosed in which the rotor assembly comprises a stack of rotor laminations having a plurality of rotor poles defining interpole regions. The rotor assembly also comprises a cage including an end plate and support bars, which may be electrically conductive, that are axially aligned within the interpolar regions that lie between adjacent rotor poles. When the support bars are electrically conductive, the support bars can become transient "flux blockers" as the rotor assembly rotates past a stator pole, blocking the flow of flux through the interpole regions and improving the performance of the motor.
