Interturn Fault Detection in IPMSMs: Two Adaptive Observer-based Solutions
Romeo Ortega, Alexey Bobtsov, Leyan Fang +2
In this paper we address the problem of online detection of inter-turn short-circuit faults (ITSCFs) that occur in permanent magnet synchronous motors (PMSMs). We propose two solut…
