Data-Driven Onboard Inter-Turn Short Circuit Fault Diagnosis for Electric Vehicles by Using Real-Time Simulation Environment

“…In addition, to further our research, we intend to extended the faulted PMSM motor model with saturation effects, which is more compatible for EV applications where the machines are often operating in highly saturated regions. [31] instead of using the original d and q stator current components, the method applies the higher harmonic index of the Park's Vector stator inter-turn faults in induction motors multiple yes lacks of reliability for low severity levels, simple [32] multilayer feedforward NN with one hidden layer stator inter-turn faults in induction motors binary yes manually labeled; no report on the capability of detecting fault at early stage; for industrial monitoring applications [33] DSP tools used for feature extraction by using higher-order statistics (HOS) and motor-current Park's vector approach (PVA)…”

“…The methods are reported to demonstrate robustness against false alarms during load and speed changes, however still have large execution times tested in the dSPACE DS1103 controller. The study [31] focuses on the stator inter-turn faults in induction motors through FEM simulations. A novel vector reliant on the higher harmonic index of the d and q components of the Park's Vector is introduced for dependable diagnosis.…”

The Fast Prognosis of Inter-Turn Faults in an Induction Motor

“…E. Ghosh and al have proposed a new approach to control the motor and reduce the imbalance caused by inter turn fault [16]. Gyftakis and Cardoso [17] use a spatial vector approach which depends on the higher harmonic index of the park vector. The frequency spectrum of the proposed vector module can be studied and analyzed to extract more information on the gravity of failure.…”
