Abstract:
A rotational power converter for converting a rotational output of an internal combustion engine into a power for driving a hybrid electric vehicle, the rotational power converter comprising:an input shaft connected to an output shaft of the engine; an output shaft for connecting to driving wheels of the vehicle; a housing; a first stator fixedly housed in the housing, the first stator having a winding for generating a rotating magnetic field; a first rotor connected to the input shaft and rotatably supported in the housing; a second rotor connected to the output shaft and rotatably supported in the housing, wherein: the first rotor is driven by the engine; a rotational power of the first rotor is electromagnetically transferred to a rotational power of the second rotor, giving a rotational power thereto; the rotational power of the second rotor is transferred to the driving wheels of the vehicle; and the rotational power of the second rotor is controlled by controlling the rotating magnetic field generated in the stator.
