A machine includes a rotor and a stator that is situated adjacent the rotor. The stator includes a plurality of wire-wound phases. The phases include at least first and second wire-wound phases that differ in temperature-responsive electrical resistance. A controller is in electrical communication with the stator. The controller is configured to identify an over-temperature condition of the stator based upon the differing temperature-responsive electrical resistance and modify the operation of the stator in response to the over-temperature condition.
