Abstract
An electric machine may include a rotor defining a cavity containing a magnet, an outer periphery and a top bridge therebetween. The top bridge defines at least two segments. Each of the segments has a width that is minimum closest to a Q-axis, is maximum closest to a D-axis, and monotonically increases from the minimum to the maximum such that during operation a rate of change of rotor magnetomotive force associated with each segment differs.
