Abstract
A six phase stator winding of a motor that has reduced MMF harmonics characteristics is provided. The stator winding has two sets: a first set and a second set of three phase winding connection. The first set and the second set of the three phase winding connection are connected parallel to each other, such that the two sets of the three-phases are shifted by 30-degree electrical angle with respect to each other, where the second set of is leading.
Claims13
An electrical machine of a vehicle, comprising:
- a rotor;
- and
- a stator,
- wherein
- the stator includes circumferentially spaced twelve slots;
- the twelve slots comprises a plurality of winding connection;
- the plurality of winding connection comprises two sets of three phase winding:
- a first set of three phase windings and a second set of three phase windings;
