Abstract
The work proposes a method for estimation of the
magnet temperature in permanent-magnet synchronous
machines by exploiting the d-axis saturation effects in the steel
stator core produced by the d-current and rotor flux excitation.
The method implies an intermittent injection of a voltage pulse
in the d-axis of the motor. The resulting d-current response is a
function of both the initial value of the d-current itself and the
magnetization level of the magnets. Thus, a temperature
dependent variation in the magnetization level of the permanent
magnets is reflected in a variation of the d-current slope upon
the voltage pulse. Experimental validation of the method is
demonstrated with surface permanent-magnet motor.
