Abstract
A method, system, and apparatus for controlling and regulating operation of a permanent magnet rotary electric machine including a stator and a rotor includes determining a first reactive power term associated with the electric machine based upon voltage, and determining a second reactive power term associated with the electric machine based upon flux. A first motor temperature associated with the electric machine is determined based upon the first and second reactive power terms, and power output from the permanent magnet electric machine is controlled based upon the first motor temperature.
