An electrically assisted turbocharger (1) having its rotor shaft (48) radially and axially rotationally positioned by planet rollers (51) in an epicyclical gear (4). This ensures a very accurate spin of the turbine shaft (48) speed. The rotor (54) from the electric motor is attached to the annulus (53) of an epicyclical gear (4). This reduces the rotor (54) speed and the thermal load. The electric motor may also function as a generator. The generator function eliminates the need for a waste gate control of the turbine shaft (48) speed. |
