Abstract
A circuit configuration supplies an electric motor with a stator and a rotor. The stator has a large number of electromagnets, arranged in particular in the form of a ring, and the rotor has a large number of permanent magnets that are associated with the electromagnets on the stator and are arranged, in particular, in the form of a ring. A rectifier circuit converts the a.c. voltage which is drawn from the supply network to a d.c. voltage. A converter circuit converts the d.c. voltage to a controllable frequency a.c. voltage for supplying the electric motor with electrical drive energy. An energy storage circuit which contains at least one accumulator is connected between the rectifier circuit and the converter circuit.
