Abstract

An electrical device includes an electromagnetic component configured to generate a magnetic flux. The electromagnetic component includes a soft magnetically-conductive material configured to pass magnetic flux therethrough along a flux path. The soft magnetically-conductive material includes at least one grain oriented portion having metal grains that are oriented parallel with respect to the magnetic flux.

Claims (23)

1. An electrical device, comprising:

an electromagnetic component configured to generate a magnetic flux; the electromagnetic component comprising a soft magnetically-conductive material configured to pass magnetic flux therethrough along a flux path, the soft magnetically-conductive material including at least one grain oriented portion having metal grains that are oriented parallel with respect to the magnetic flux,

wherein the stator comprises a transition region interposed between a plurality of stator teeth and an outer yoke portion, wherein at least one of one or more stator teeth and the exterior yoke portion has a grain oriented metal portion, and

wherein the transition region has a non-grain oriented portion including metal grains having a substantially random orientation that does not match the magnetic flux paths of the transition region.

2. The electrical device of claim 1 , wherein the electromagnetic component includes a stator disposed adjacent a rotor that rotates with respect to the stator.

3. The electrical device of claim 2 , wherein the stator comprises the soft magnetically-conductive material.

4. The electrical device of claim 3 , wherein the soft magnetically-conductive material is electrical steel comprising iron (Fe) and silicon (Si).

5. The electrical device of claim 3 , wherein the grain oriented metal portion has a grain orientation that substantially matches a flux orientation of the flux path.

6. The electrical devices of claim 5 , wherein a first grain oriented metal portion of the stator teeth extending in direction transverse to a respective stator tooth.

7. The electrical device of claim 6 , wherein a second grain oriented metal portion of the outer yoke portion has a circumferential orientation extending along a circumference of the outer yoke portion.

8. The electrical device of claim 1 , wherein the rotor includes at least one grain oriented metal rotor portion having rotor metal grains oriented substantially parallel to the metal grains of the first grain oriented metal portion.

9. The electrical device of claim 1 , wherein the electromagnetic component includes a plurality of vertical straps and a plurality of horizontal straps that define an electrical transformer.

10. The electrical device of claim 9 , wherein each vertical strap includes a first vertical end coupled to a first horizontal end of a respective horizontal strap to define a corner zone, the corner zone including arched metal grains extending in an arched manner from the vertical strap to the horizontal strap.

11. The electrical device of claim 10 , wherein the plurality of vertical straps includes a pair of opposing outer vertical straps and a center vertical strap interposed between the outer vertical straps, and

wherein the plurality of horizontal straps includes a first horizontal strap having a first horizontal end connected to a first vertical end of the first outer vertical strap and a second horizontal end coupled to a first end of the center vertical strap, and second a horizontal strap having a first horizontal end connected to a first vertical end of the second outer vertical strap and a second horizontal end coupled to the first end of the center vertical strap.

12. The electrical device of claim 11 , wherein the first end of the center vertical strap includes a non-grain oriented metal portion.

13. The electrical device of claim 10 , wherein the vertical straps on the horizontal straps are formed of electrical steel comprising iron (Fe) and silicon (Si).

14. An electrical device, comprising:

an electromagnetic component configured to generate a magnetic flux; the electromagnetic component comprising:

a soft magnetically-conductive material configured to pass magnetic flux therethrough along a flux path, the soft magnetically-conductive material including at least one grain oriented portion having metal grains that are oriented parallel with respect to the magnetic flux; and

a plurality of vertical straps and a plurality of horizontal straps that define an electrical transformer, each vertical strap includes a first vertical end coupled to a first horizontal end of a respective horizontal strap to define a corner zone, the corner zone including arched metal grains extending in an arched manner from the vertical strap to the horizontal strap,

wherein the plurality of vertical straps includes a pair of opposing outer vertical straps and a center vertical strap interposed between the outer vertical straps, and wherein the plurality of horizontal straps includes a first horizontal strap having a first horizontal end connected to a first vertical end of the first outer vertical strap and a second horizontal end coupled to a first end of the center vertical strap, and second a horizontal strap having a first horizontal end connected to a first vertical end of the second outer vertical strap and a second horizontal end coupled to the first end of the center vertical strap, and

wherein the first end of the center vertical strap includes a non-grain oriented metal portion.
