Abstract

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 a dual wound coil. The coil ends of a dual wound coil can be on a common side, simplifying wiring. The dual wound coil may be configured with a low resistance, reducing resistive losses.

Claims

AMENDED CLAIMS received by the International Bureau on 9 July 2012 (09.07.2012) CLAIMS What is claimed is;
1. An electrical coil assembly, comprising:
a first electrical coil contiguous to a second electrical coil, the first electrical coil and the second electrical coil formed from a single wire having a first end and a second end; wherein the first electrical coil and the second electrical coil are wound in the same direction, with a cross-over transition between the first and second coil occurring on the outer layer of the electrical coil assembly, and
wherein the first end and the second end of the single wire terminate on the inside of the first electrical coil and the second electrical coil, respectively, and wherein the electrical coil assembly is a dual wound coil.
2. The electrical coil assembly of claim 1, wherein the first end and the second end of the single wire terminate adjacent to each other.
3. The electrical coil assembly of claim 1, further comprising an adhesive bonding the first electrical coil to the second electrical coil.
4. The electrical coil assembly of claim 1, wherein the single wire has a length in excess of 3.81 meters (150 inches),
5. An electrical machine; comprising;
a rotor;
a stator; and
a dual wound coil,
wherein the electrical machine is at least one of a transverse flux machine or a commutated flux machine, and wherein the dual wound coil comprises;
a first electrical coil contiguous to a second electrical coil, the first electrical coil and the second electrical coil formed from a single wire having a first end and a second end;
wherein the first electrical coil and the second electrical coil are wound in the same direction, with a cross-over transition between the first and second coil occurring on the outer layer of the dual wound coil, and wherein the first end and the second end of the single wire terminate on the inside of the first electrical coil and the second electrical coil, respectively.
6. The electrical machine of claim 5, wherein the coil is configured with a wire length in excess of 3.81 meters (150 inches).
7. The electrical machine of claim 5, wherein the electrical machine comprises a plurality of dual wound coils, and wherein the electrical machine is a polyphase machine.
8. The electrical machine of claim 5, wherein the stator comprises a lamination stack and a powdered metal tooth.
9. A method of winding a dual wound coil, the method comprising: coupling a first end of a coil wire to a first mandrel portion of a mandrel;
coupling a second end of the coil wire to a second mandrel portion of the mandrel; coupling the first mandrel portion to the second mandrel portion such that the first mandrel portion and the second mandrel portion are rotatable about a common axis;
simultaneously rotating the first mandrel portion in a first direction about the common axis and the second mandrel portion in a second direction about the common axis to wind the wire on the mandrel to form a dual wound coil, wherein the second direction is opposite the first direction.
10. The method of claim 9, further comprising applying epoxy to hold the dual wound coil in a desired configuration.
11. The method of claim 9, wherein the dual wound coil is wound in one direction when traversed from the first end to the second end.
12. The method of claim 9, wherein the coil wire is a continuous wire piece.
13. The method of claim 9, wherein the first end of and the second end of the coil wire are disposed on the inside of the dual wound coil after the rotating.
14. The method of claim 9, wherein the first end and the second end are adjacent to each other after the rotating.
15. The method of claim 9, wherein the length L of the coil wire is selected according to the equation L = (N * ? * ((Dl + DO ) / 2) + 2E.
