An on-line diagnostic approach of open-phase faults for a five-phase permanent magnet synchronous motor (PMSM) fed by a closed-loop vector-controlled drive is presented in this paper. This approach is accomplished based on the magnetic field pendulous oscillation (MFPO) phenomenon, in which a significant "swing-like" pendulous oscillation in the magnetic field is observed in case of open-phase faults. According to analysis of the signatures of MFPO patterns under faulty conditions, all possible open-phase faults are detected, including single-phase open faults, two-adjacent phase open faults, and two-nonadjacent phase open faults.Moreover, this approach is capable of localizing the faulted phase/phases by further extracting the phase angle features of MFPO angular position waveforms under faulty conditions. Meanwhile, in order to minimize the number of sensors to reduce the implementation cost of this diagnostic approach, a phase-locked loop (PPL) technique is developed to overcome the fault masking difficulties associated with the compensation action of the closed-loop vector-controlled drive. As a result, this diagnostic approach only requires four current sensors, which are typically already available in five-phase PMSM drive systems for control purpose. Finally, experimental results demonstrate the effectiveness of the presented approach.

“…On this basis, Fan and Hang [18,19] identified the fault phase by introducing the phase of the zero sequence voltage. Mirafzal, Sayed-Ahmed and He [20][21][22][23][24] proposed an inter-turn fault diagnosis method based on the pendulous oscillation phenomenon. This method can detect the inter-turn fault and identify the fault phase in accordance with the space vectors of the stator current and voltage.…”

This study proposes a novel inter-turn fault diagnosis method for a permanent magnet synchronous machine. Search coils are set on every stator tooth to measure the tooth fluxes. The high-order harmonics produced by the inverter are adopted to diagnose the inter-turn fault existence and locate the fault tooth. The fault severity coefficient is proposed on the basis of theoretical analysis and can identify the fault severity. A comparative analysis of a traditional method based on co-simulation shows that the proposed method is sensitive and that the fault severity coefficient is accurate, intuitive and independent of the operating condition of the motor. An experimental platform is set up, and it validates the effectiveness of the proposed method.

“…presented both continuous and discrete wavelet to detect many mechanical and electrical induction motor faults using MCSA. (Sayed-Ahmed et al, 2007) studied the inter-turn short circuit in one phase of a stator winding of an induction motor energized from a vector controlled drive. The induction motor requires a variable frequency three phase source for variable speed operation.…”
