Abstract
At least one example embodiment discloses a method of estimating a rotor magnet temperature of a motor. The method includes determining an applied voltage during operation of the motor at an operating point, obtaining a reference value associated with the operating point and associated with a reference temperature and determining an estimated rotor magnet temperature based on the applied voltage and the reference value.
