Abstract:

An electric machine includes a plurality of teeth separated by a plurality of slots positioned on an armature of the electric machine. Each of the teeth may include at least one bifurcation. A plurality of magnets may be arranged on a main field of the electric machine to form an axial array group. The magnets in the axial array group may be arranged in the main field with respect to each other to create a multi-stepped arrangement having a predetermined step angle. The step angle is determined based on the positioning of the bifurcations and the slots.
