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.
Claims13
An electric machine, comprising:
- a stator;
- and
- a rotor that can move relative to the stator,
- the stator comprising a first and at least one second winding system that have coils which are inserted in slots of the stator and wound around teeth of the stator in each case,
- wherein the first winding system and the second winding system each comprise at least one winding-free tooth,
- wherein all teeth of the stator are provided with a winding when the first and second winding systems are combined, and
- wherein the number of coils per electric phase and per winding system is greater than or equal to two, or the at least one winding-free tooth is positioned directly between the two teeth wound with coils of the same winding system and the same electric phase.
