Semi-physical demagnetization model for the temperature dependency of permanent magnets in electrical machines

AIP Advances, 2023
Losses during the operation of electrical machines heat up permanent magnets which in turn changes their demagnetization behavior. An elevation of permanent magnet’s temperature usually correlates to a decreasing remanence and coercivity.
