Mixed resistive unbalance and winding inter-turn faults model of permanent ma…

This work analyzes the behavior of surfacemounted permanent magnet synchronous motors (SPMSMs) operating under stator faults. The studied faults are resistive unbalance and winding inter-turn short circuits, which may lead to unbalanced conditions of the motor. Both faults may reduce motor efficiency and performance and produce premature ageing. Thiswork develops an analytical model of the mot…
