Abstract
The proposed principle relates to an electric machine having a stator (1) and a rotor (2) that can move relative to the stator. The stator (1) comprises a first and at least one second winding system (4, 5) that have coils, each of which is placed in stator slots (3) and is wound around stator teeth (6). The first winding system (4) and the second winding system (5) each have at least one tooth (7) around which no coil is wound. When combining the first and second winding system (4, 5), all teeth of the stator (1) have coils wound around them.
