Abstract: A double-stator rotating electric machine includes a rotor and a pair of outer and inner stators. The outer stator has a first multi-phase coil wound thereon so as to form magnetic poles upon energization of the first multi-phase coil. The inner stator has a second multi-phase coil wound thereon so as to form magnetic poles upon energization of the second multi-phase coil. The number of the magnetic poles formed by the outer stator is equal to the number of the magnetic poles formed by the inner stator. Each of the magnetic poles formed by the outer stator is located at the same circumferential position as and has an opposite polarity to a corresponding one of the magnetic poles formed by the inner stator. The rotor has yoke portions each of which radially extends so as to form a magnetic flux passage magnetically connecting the outer and inner stators.

Abstract: A device for driving a vehicle including an engine that serves as a power source of the vehicle, and a transmission that is connected to the engine, the engine and the transmission being arranged longitudinally such that an axial direction of an output shaft of the engine accords with a front-rear direction of the vehicle includes a motor generator (MG) that serves as a power source of the vehicle, and a speed reducer that is connected to the MG. The MG and the speed reducer are arranged outside of an engine compartment that accommodates the engine. An output shaft of the speed reducer is connected to a power transmission system, which transmits power of an output shaft of the transmission to a drive shaft of a vehicle wheel, to be capable of transmitting its power to the power transmission system.

Abstract: A rotor includes a rotor core and permanent magnets. The rotor core includes annular bodies that are stacked in a stacking direction and each formed of core segments arranged along a circumferential direction. The number of the core segments in each of the annular bodies is set based on k, where k is the number of magnetic poles formed by the permanent magnets. The rotor core has n through-holes, where n≧k. The rotor further includes n fixing members each of which extends in the stacking direction through one corresponding through-hole of the rotor core. Between each circumferentially adjacent pair of the core segments, there is formed a gap that is greater than a clearance provided between the through-holes of the rotor core and the fixing members. At least one of the annular bodies is circumferentially offset from another annular body by an integer multiple of one magnetic pole.

The rotor includes a laminated core of core sheets made of soft magnetic material and an end-surface core disposed on a surface of the laminated core on a second axial end of the rotor. The laminated core includes segments joined in a ring and each formed with a salient pole structure at each of radially inner and outer peripheries thereof. The end-surface core includes soft magnetic sections made of steel and non-magnetic sections made of stainless steel, which are joined together in a ring. The laminated core is held between the rotor arm and the end-surface core, and fixed to the rotor arm by rivets penetrating through the rotor arm, laminated core and the end -surface core.
