An electric machine 16 for a hybrid vehicle comprises a stator housing 20, a stator 22, a rotor 24 and two wet clutches 26,28 within the stator housing 20, which include non-ferrous plates immersed in hydraulic fluid. This can clean debris from the plates and cool the machine 16. The rotor 24 lies inside the stator 22 and can be connected to an engine 12 by the first clutch 26. It can also be connected to a transmission 14 by the second clutch 28. The clutches 26,28 may be mounted radially inside the rotor 24. The vehicle's powertrain 10 may also include a damper between the engine 12 and the first clutch 26. The machine 16 may be selectively operated as a starter motor, as a generator or as a motor working in series with the engine 12. |
