Abstract

An electric machine includes a unitary, single material substrate defining a rotor lamination including a first region having a predefined magnetic permeability. The rotor lamination includes an arc-shaped second region having a magnetic permeability less than the first region. The second region is oriented such that it impedes flux associated with magnets contained by the first region and perpendicular to quadrature flux field lines associated with the magnets.
