High-Frequency Voltage Injection Based Stator Interturn Fault Detection in Permanent Magnet Machines
Publikováno v:
IEEE Transactions on Power Electronics. 36:785-794
An interturn short-circuit fault in the stator winding of an electric machine, denoted as turn fault, has been recognized as one of the most severe faults in permanent magnet machines, which require a swift and reliable detection, in order to impleme

Interturn short-circuit fault, also known as turn fault, is a common fault in electric machines, which can cause severe damages if no prompt detection and mitigation are conducted. This article proposes a turn fault detection method for permanent mag
