Permanent magnet motor having stator poles with stepped-end-surfaces and rotor with outer-circumferential-recessed surface










Image Number 14 for United States Patent #7550891.

A permanent-magnet motor including a rotor having permanent magnets disposed therein, and a stator, wherein an outer circumferential surface of the rotor is opposite to an inner circumferential surface of the stator, and one or both of the outer circumferential surface of the rotor and the inner circumferential surface of the stator are varied in a radial direction so as to provide a non-uniform gap between the two surfaces to approximate sinusoidal change in magnetic flux.
