Recent Advances in Modeling and Online Detection of Stator Interturn Faults in Electrical Motors

Modeling and Analysis of PMSMs under Inter Turn Short Faults

“…To implement the proposed model, (12), (14), (15), and (16) , the transient element vanishes and the proposed model simulation results are almost identical to the FEM simulation results. Fig.…”

“…In some applications such as the EV and the wind power generator, the PMSM fault detection is one of the most important issues due to the safety and high fault time cost. One common fault of the PMSM is a winding turn short fault caused by the coil insulation failure [1,3,6,13,14,17]. Since the coil insulation material is under the high voltage and temperature stress, it degrades gradually and finally loses the insulation characteristic which is called the inter turn short fault.…”

“…However, like the negative sequence detection scheme, these frequency analysis scheme need the rich pretest also. In [10][11][12][13][14][15][16][17], the turn short fault models of the PMSM have been presented. They used the winding function [10,15] or simplified model [11,12,13,16,17] to obtain inductance value with turn short fault.…”

Analysis of Vertical Strip Wound Fault-Tolerant Permanent Magnet Synchronous Machines

“…In the early studies [24][25][26][27][28][29][30], the dynamic behavior of RCW wound PMSM under healthy, faulty and post-fault control operating conditions have been investigated in both FE coupled dynamic models [31] and lumped-parameter dynamic model based on parameters calculated with FE [28]. However, in these early studies the influence of the location and geometry of the faulty winding on the fault behavior are not considered.…”

Interturn Fault Diagnosis in Interior Permanent Magnet Synchronous Motors Using Negative-Sequence Impedance

“…분석(signal-based analysis)이 있다 [5]. 전동기 전류 신호 분석은 전동기의 전류 정보를 이용한 방법 으로 푸리에 해석과 같은 주파수 해석 방법을 통해 전동기의 권 선 간 고장을 진단한다.…”
