Abstract: A drive unit for a hybrid vehicle that is downsized without reducing N.V. performance. The drive unit comprises: a geared transmission that transmits torque between a power split mechanism and a differential unit; and a reduction mechanism that multiplies torque of a second motor to be delivered to the differential unit. In the drive unit, an engine, a first motor, the power split mechanism, and a counter drive gear are arranged around a first rotational axis, the differential unit, the second motor, the reduction mechanism, driveshafts, and a differential ring gear are arranged around a second rotational axis, and a counter driven gear is arranged around a third rotational axis. The reduction mechanism is positioned without overlapping with the engine, the first motor, and the counter drive gear in an axial direction.

Abstract: In a rotor core (12) of a rotor (10), a core interior refrigerant path is formed. The core interior refrigerant path includes a first refrigerant path (22) formed for every magnetic pole and extending along each q axis from the outer circumferential end of the rotor core (12) toward the inner circumference of the rotor core (12); a second refrigerant path (24) formed for every other magnetic pole and extending along a d axis from the inner circumferential end of the rotor core (12) to a position closer to the inner circumference than the permanent magnet (16) is; and a third refrigerant path (26) extending in a rotor circumferential direction at a position displaced in the rotor shaft direction relative to the first refrigerant path (22) to provide fluid communication between the first refrigerant path (22) and the second refrigerant path (24).

Abstract: A stator for a rotary electric machine includes an annular yoke, and teeth projecting from the yoke in a stator radial direction. Both ends of each of the teeth in a stator axial direction include reduced-width parts. The width of each of the reduced-width parts is smaller than the width of the remaining part of each of the teeth. Stator coils each is wound around each of the teeth in concentrated winding, and includes at least one curved portion in a coil end portion. The curved portion corresponds in position to at least part of the reduced-width parts.

Abstract: A rotor related to the present invention is for a rotary electric machine. The rotor includes a rotor core and magnets. The rotor core has a plurality of core refrigerant passages. The core refrigerant passage each includes an inlet passage, a magnet cooling passage and an outlet passage. The inlet passage is configured such that a liquid refrigerant flows into the inlet passage from a shaft refrigerant passage. The magnet cooling passage is configured such that the liquid refrigerant flows into the magnet cooling passage from the inlet passage. The magnet cooling passage extends in an axial direction. The outlet passage is configured to flow the liquid refrigerant from the magnet cooling passage to a gap. An axial position of the outlet passage in the rotor core is at one place at a central position in the axial direction.

Abstract: To suppress occurrence of a counter electromotive force due to a permanent magnet motor, in an electric vehicle that includes a permanent magnet motor and a non-permanent magnet motor rotating a drive shaft. An electric vehicle includes a permanent magnet type PM motor that rotates a front wheel drive shaft. The PM motor and the drive shaft are connected and disconnected by a clutch. The electric vehicle also includes a non-permanent magnet type SR motor that rotates a rear wheel drive shaft. When the clutch disconnects the PM motor and the drive shaft, the SR motor rotates the drive shaft.
