Patent ID: 7675254

Claim:
A drive for a vehicle as the main drive or as a hybrid drive, comprising: an electric motor with a stator and a rotor and an electronic control device which can be connected to a current source for commutation of the winding phases of the electric motor, the electric motor being a reluctance motor of special type, for the stators of which each of the coils (a, b, c, d) of the winding phases encloses a plurality of stator teeth or one stator tooth, the rotor comprising a field winding and an electronic control device having a number of half-bridges corresponding to the number of winding phases with free-wheeling diodes, and field winding of the rotor being connected to the current source by way of a transistor in braking operation and thus by controlling the field current of the field winding precision braking operation of the reluctance motor can be carried out and the braking current which forms in the winding phases is supplied to the current source by way of the free-wheeling diodes of the half-bridges.
