Abstract

In this paper, a novel nonintrusive online rotor PM temperature tracking method for permanent magnet synchronous machine (PMSM) based on the third harmonic voltage is proposed. The proposed method is not affected by inverter nonlinearities and requires no information of winding resistance, d- and q-axis inductances. It is also robust to the speed variation and introduces no perturbation signals. The third PM flux-linkage is estimated and used as the indicator of the rotor PM temperature. Analytical model for the third harmonic voltage based on the magnetic permeance modulation is proposed to analyze the influence of armature currents. Corresponding third PM flux-linkage amplitude extractor is designed based on this analytical model. Moreover, 2 dimensional finite element analysis is also carried out to verify the effectiveness of the proposed analytical model. Self-commissioning method of the third harmonic flux-linkage tracker is also proposed. Finally, experiments on the 12/slot-10/pole surface mounted permanent magnet synchronous machine verifies the proposed online rotor PM temperature tracking method.
