Abstract
A stator is for an electrical machine. The stator includes: a stator body with stator grooves; a winding system with winding cables, at least two of the winding cables being arranged in each of the stator grooves; phase pins configured so as to be connected to different electrical phases of a power supply; and a switching device, via which at least one of the winding cables per each of the stator grooves is selectively connectable to two different phase pins such that, in a first switching state of the switching device, the winding cables arranged in the same stator groove are all connected to the same phase pin, and, in a second switching state of the switching device, the winding cables arranged in the same stator groove are connected to at least two different phase pins.
Claims5
A stator for an electrical machine, the stator comprising:
- a stator body comprising a plurality of stator grooves;
- a winding system comprising a plurality of winding cables, wherein at least two of the winding cables are arranged in each of the stator grooves;
- a plurality of phase pins, which are configured so as to be connected to different electrical phases of a power supply;
- and
- a switching device, via which at least one of the winding cables per each of the stator grooves is selectively connectable to two different phase pins of the plurality of phase pins such that, in a first switching state of the switching device, the winding cables arranged in the same stator groove are all connected to the same phase pin, and, in a second switching state of the switching device, the winding cables arranged in the same stator groove are connected to at least two different phase pins.
