Abstract: An improved rotor assembly configured for magnets with differing lengths, and methods and systems for manufacturing the same. The rotor assembly may be created by selectively creating first and second tabs extending into apertures of lamination sheets. The first and second tabs may be selectively removed, depending on the different magnet lengths and the specific lamination sheet, according to one of a first finishing schedule and a second finishing schedule. The lamination sheets are stacked with any remaining first and second tabs, and other features, aligned.

Abstract: An interior permanent magnet machine includes a rotor having a plurality of slots. First and second slots are disposed in a first pole and the third and fourth slots are disposed in a second pole. A first angle is defined between respective centerlines of the first and second slots. A second angle is defined between respective centerlines of the third and fourth slots. The first angle is configured to be sufficiently different from the second angle so that torque ripple is reduced. Thus the rotor is configured such that the angular configuration of slots in a first pole is different from the angular configuration of slots in a second pole of the rotor.
