ABSTRACT:
The invention relates to an electrical machine, in particular to a motor or a generator, comprising at least a stator (30a,30b), a plurality of winding teeth (32a, b) arranged on the circumference of the at least one stator (30a, b) with windings and the winding teeth comprising clearances (34a, b) therebetween, wherein all windings of each stator are connected in series. The electrical machine further comprises a rotor (1) and a plurality of permanent magnets (5) and/or rotor windings arranged at the circumference of the rotor (1), wherein the poles of the permanent magnets and/or rotor winding directions are radially aligned and alternating. Preferably, two stators (30a, b) are provided, which have an angular offset (a) to each other. Further, a control circuit for an electrical machine comprising at least one phase winding is provided, the control circuit comprising four power switches per corresponding phase winding for the control of the electrical machine.
