The drive unit has at least one asynchronous electrical machine (1), driven by an i.c. engine (2) and at least one electric propulsion motor (7), which is supplied from the asynchronous electrical machine via a current converter (3) and an intermediate circuit (4). The latter may be coupled to a supply device (8), for providing a rotary field for operation of the asynchronous machine as a starter motor, via the current converter. |
