PWM-based Flux linkage estimation for permanent magnet synchronous machines
The Journal of Engineering, 2019 Monitoring of rotor temperature in permanent magnet synchronous machines (PMSM) is of great importance as high temperature could cause partial or even irreversible demagnetisation of the permanent magnets (PMs).
