Abstract

A stator winding for an electric machine includes two or more conductors defining one or more phases about the stator winding. Each phase includes at least two conductors of the two or more conductors arranged in an electrically switchable relationship. An end of each conductor of the two or more conductors extends to an exterior of the electric machine and is configured for independent electrical connection to a component at the exterior of the electric machine. An electric machine includes a stator having a stator winding including two or more conductors defining one or more phases about the stator winding including at least two conductors of the two or more conductors arranged in an electrically switchable relationship. An end of each conductor of the two or more conductors extends to an exterior of the electric machine for independent electrical connection to a component at the exterior of the electric machine.

Claims

1. A stator winding for an electric machine comprising:

two or more conductors defining one or more phases about the stator winding, each phase including at least two conductors of the two or more conductors arranged in an electrically switchable relationship, an end of each conductor of the two or more conductors extending to an exterior of the electric machine and configured for independent electrical connection to a component at the exterior of the electric machine.

2. The stator winding of claim 1, wherein each conductor of the two or more conductors are configured such that each conductor may be individually energized and/or deenergized.

3. The stator winding of claim 2, wherein the energizing and/or deenergizing of individual conductors of the at least two conductors increases or reduces a number of effective stator turns in the stator winding.

4. The stator winding of claim 1, wherein the two or more conductors comprise three phases.

5. The stator winding of claim 1, wherein each phase includes two conductors of the two or more conductors arranged in the electrically switchable relationship.

6. The stator winding of claim 1, wherein each conductor of the two or more conductors extends independently from the stator winding through a housing of the electrical machine.

7. The stator winding of claim 1, wherein the component is an inverter.

12. The electric machine of claim 7, wherein each phase includes two conductors of the two or more conductors arranged in the electrically switchable relationship.

8. An electric machine comprising:

a rotor disposed at a central axis; and

a stator disposed at the rotor including;

a stator core; and

a stator winding including;

two or more conductors defining one or more phases about the stator winding, each phase including at least two conductors of the two or more conductors arranged in an electrically switchable relationship, an end of each conductor of the two or more conductors extending to an exterior of the electric machine and configured for independent electrical connection to a component at the exterior of the electric machine.

9. The electric machine of claim 8, wherein each conductor of the two or more conductors are configured such that each conductor may be individually energized and/or deenergized.

10. The electric machine of claim 9, wherein the energizing and/or deenergizing of individual conductors of the at least two conductors increases or reduces a number of effective stator turns in the stator winding.

11. The electric machine of claim 8, wherein the two or more conductors comprise three phases.

13. The electric machine of claim 8, wherein the component is an inverter.

14. The electric machine of claim 8, wherein each conductor of the two or more conductors extends independently from the stator winding through a housing of the electrical machine.
