Exploring the Phase Angle of Measured Speed Harmonic for Efficient Permanent Magnet Temperature Estimation of PMSMs
Abstract
This paper investigates the use of the phase angle of the measured speed harmonics for efficient permanent magnet (PM) temperature estimation of permanent magnet synchronous machine (PMSM). Based on the mechanical model, a linear estimation model is derived to model the relationship between the PM temperature and the phase angle of the speed harmonic. This model shows that there is a linear relationship between the PM temperature and the …
