Abstract
A stator tooth design for a stator core of a permanent magnet motor. The tooth surface comprises a plurality of surface segments, wherein each surface segment of the plurality of surface segments joins an adjacent surface segment of the plurality of surface segments at an obtuse angle, preferably between 160 and 170 degrees. Alternatively, the tooth surface comprises a single essentially straight surface segment. Each of the plurality of surface segments has a starting edge and an ending edge. Preferably, the starting edge of a surface segment lies along a first circumferential path a predetermined radial distance from the outside edge of the stator core and the ending edge of the surface segment lies along a second circumferential path either closer to or further from the outside edge. The first circumferential path and the second circumferential path can be concentric to the outside edge of the stator core.
