    Abstract : Accurate knowledge of the temperature of a Permanent Magnet Synchronous Machine is of high importance, not only to ensure safe operation and improve control of the operating point, but also to avoid irreversible demagnetization of rare-earth permanent magnets. However, direct measurement using thermal sensors is not suitable for high volume and low-cost applications, due to costly sensor installation and maintenance, and therefore, the magnet temperature needs instead to be estimated.
