Transverse and/or commutated flux systems having laminated and powdered metal portions

摘要

Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve increased efficiency, increased output torque, and/or reduced operating losses via use of laminated materials in connection with powdered metal materials. For example, stacks of laminated materials may be coupled to powdered metal teeth to form portions of a stator in an electrical machine.

主权项

1. An electrical machine, comprising:
a rotor configured to rotate around an axis of rotation; a coil wound about the axis of rotation; and a stator comprising:
a lamination stack coupled to a tooth,a first stator half, comprising
a plurality of said lamination stacks with interlocking features forming a generally ring-shaped structure; anda plurality of teeth coupled to the generally ring-shaped structure, wherein, in a first position of the rotor, flux is transferred from the plurality of teeth to the rotor; wherein, in a second position of the rotor, flux is transferred from the rotor to the plurality of teeth; a back return lamination coupling the first stator half to a second stator half; wherein the lamination stack comprises silicon steel, wherein the tooth comprises powdered metal, and wherein the electrical machine is at least one of a transverse flux machine or a commutated flux machine.
