Abstract
A rotor component that comprises a rotor circuit configured for use with either an interior permanent magnet (IPM) machine or a synchronous reluctance machine (SRM) that includes a pole circuit made of a conductive, non-magnetic material and has a midpoint that substantially aligns with a d-axis of the IPM or SRM. An electric machine with a similar rotor component therein or having a loop or ring of a conductive, non-magnetic material that is substantially concentric about a d-axis of the electric machine.
