JMAG - Demagnetization study of permanent magnets in electric motors

For reasons of performance and durability, the demagnetization problem of permanent magnets is crucial. In fact, this phenomena leads to an irreversible degradation of the remanent flux density of permanent magnets. We perform using the JMAG software, a 2D finite element modeling of the electric motors coupled with the appropriate electric circuit, to analyze this phenomena.
