Abstract
An electric machine including a rotor and a stator and having a first winding. The stator slots define a plurality of layer positions wherein each of the layer positions is at a different radial distance from the axis. There is an odd number of select stator slots wherein for two slot segments disposed in different layer positions, a pair of end loops connect each of the slot segments with another slot segment in a different slot that is in the same layer position. In some embodiments, at least 60 percent of the end loops connect slot segments that are disposed in different layer positions. For some embodiments, only a single select stator slot is provided with the end loops being positioned to reduce spatial conflicts.
