Abstract

Magnet demagnetization in permanent magnet synchronous machines (PMSMs) can produce inadmissible performance degradation. Search coils (SCs) have been proven to be a viable option for its detection. Limitations of existing methods using SCs include the low sensitivity and the need of a large number of SCs. This paper proposes two methods for demagnetization detection of PMSMs using SCs which overcome these limitations. Zero-sequence voltage-based method relies on the zero-sequence voltage of three SCs electrically shifted 120 electrical degrees. On the other hand, differential voltage-based method computes the difference between the voltage induced in SCs with the same electrical angle, i.e., both SCs are electrically shifted 360 1 1 This work was supported in part by the Research, Technological Development and Innovation Programs of the Spanish Ministry of Science and Innovation, under grant PID2019-106057RB-I00
