Abstract

A switched reluctance motor includes at least four stator poles and an electrically conductive material around each of the stator poles. The geometric outline, on one side of the stator pole, of at least one of the conductive materials is not rectangular, as viewed from a cross-section of the switched reluctance motor showing each of the stator poles.

Claims (9)

1. A switched reluctance motor comprising:

four stator poles; and

an electrically conductive material around each of the stator poles, wherein:

for one of the conductive materials on one side of one of the stator poles, as viewed from a cross-section of the switched reluctance motor showing each of the stator poles;

the geometric outline is a rectangle with a rectangular portion of the rectangle absent,

both dimensions of the absent rectangular portion are smaller than both dimensions of the rectangle,

each dimension of the absent rectangular portion is parallel to a dimension of the rectangle, and

portions of two of the rectangles four edges constitute two edges of the absent rectangular portion.

2. The switched reluctance motor of claim 1 , wherein the geometric outline is the shape of the letter “L.”
