Abstract: An electrical machine which has a moving part and a stationary part. The moving part is in the form of an inner rotor without windings, and the rotor which has at least two magnetic conductors, which are separated from one another axially such that impeller wheels are formed. The stationary part has a number of magnetically acting webs in the circumferential direction of the machine. The webs are operatively connected to the magnetic conductors of the rotor. The stationary part has at least one first winding structure which is likewise operatively connected to the axially separated magnetic conductors of the rotor. In addition, a second winding structure is included on the webs wherein either the first winding structure acts as an armature winding and the second winding structure acts as a field winding, or vice versa. The impeller wheels are radially innerly magnetically effectively connected by means of a further magnetic conductor.
