Abstract:
A motor having a rotor including first outer surface segments providing uniform air gaps and second outer surface segments providing non-uniform air gaps. The rotor has an outer surface contour comprising a number of first outer surface segments defined by arcs having a first radius centered on a central longitudinal axis and a number of second outer surface segments defined by lines other than arcs having a first radius centered on a central longitudinal axis.
