Patent ID: 8860275

Claim:
An interior permanent magnet machine comprising: a rotor configured to magnetically interact with a stator; a first divider and a second divider integrally formed within the rotor and configured to create a first layer of three respective first segments, each of the respective first segments being substantially arc-shaped; a plurality of first magnets positioned within the first layer, the first magnets being substantially arc-shaped and defined around an arc center; a third divider and a fourth divider integrally formed within the rotor and configured to create a second layer of three respective second segments, each of the respective second segments being substantially arc-shaped; a plurality of second magnets positioned within the second layer, the second magnets being substantially arc-shaped; a first angle defined by the first divider between a first centerline extending through the first divider and a center axis extending through the arc center; a second angle defined by the second divider between a second centerline extending through the second divider and the center axis; a third angle defined by the third divider between a third centerline extending through the third divider and the center axis; a fourth angle defined by the fourth divider between a fourth centerline extending through the fourth divider and the center axis; and wherein the rotor is configured such that the first angle is the same as the second angle and the first angle is different from the third angle.
