Abstract
There is provided an electric machine that includes a rotor comprising a pole and magnet assemblies divided axially in a first subsection and a second subsection. Each of the first and second subsections includes poles and magnets, and the poles and magnets of the first subsection are offset from the poles and magnets of the second subsection.
Claims20
An electric machine, comprising:
- a rotor comprising a first pole and magnet assembly and second pole and magnet assembly, each pole and magnet assembly being divided axially in a first subsection including a first set of peripherally alternating poles and magnets and a second subsection including a second set of peripherally alternating poles and magnets;
- wherein, in each pole and magnet assembly, the first subsection is rotationally displaced in a direction opposite the second subsection;
- wherein, the first and second subsections of the first pole and magnet assembly are arranged in an alternating rotational displacement pattern with respect to the first and second subsections of the second pole and magnet assembly;
- and
- wherein a position of a first magnet in the first set is offset from a position of a second magnet in the second set such that magnets of the first subsection and magnets of the second subsection form a herringbone pattern.
