Abstract
A rotary electric motor in which a stator comprises a first number of permanent magnet poles substantially similar to each other in configuration and spaced substantially equidistantly with alternating polarity along a radial air gap, and a rotor that comprises a second number of salient poles distributed along the radial air gap, the salient poles divided in groups that have magnetic circuits isolated from each other. The radial distance between rotor salient poles of each group and the radial difference between the stator permanent magnet poles are substantially the same.
