Real-time demagnetization assessment of PM synchronous machine
This paper presents a real-time permanent magnet (PM) demagnetization assessment in permanent magnet synchronous machines (PMSM) using a physics-based model. The model is enabled to estimate the resultant normal magnetic flux density on the face of PM in a PMSM. The model is a function of physical geometry and material of the PMSM, physics of demagnetization, and the ambient temperature. The demagnetization assessment during PMSM operation is verified numerically on three typical PMSM topologies using the modified FE-based coupled thermal-field-circuit phase variable model and the results are discussed.
