Abstract:
A stator includes insulation including a back insulation portion covering a back stator portion, a first tooth portion covering a first tooth, a second tooth portion covering a second tooth. A first flange portion has a first face that is in facing relationship with the back insulation portion. A second flange portion has a second face that is in facing relationship with the back insulation portion. The first face and the second face together substantially defining a boundary plane, such that a cross-sectional slot area is defined between the back insulation portion, the first tooth portion, the second tooth portion, and the boundary plane. A plurality of conductive wires are arranged in the cross-sectional slot area, the wires defining a cross-sectional winding area within the cross-sectional slot area. A ratio of the cross-sectional winding area to the cross-sectional slot area is greater than or equal to 0.45.
