Abstract
A system for determining a temperature of a permanent magnet in a machine includes a voltage sensor that generates a voltage signal reflective of a stator voltage and a current sensor that generates a current signal reflective of a stator current. A processor receives the voltage and current signals and generates a temperature signal reflective of the temperature of the permanent magnet in the machine. A method for controlling a load of a machine includes generating a voltage signal, a current signal, and a temperature signal reflective of the temperature of a permanent magnet in the machine. The method further includes adjusting the load of the machine based on the temperature signal.
