Comparison and Analysis of Post-Fault Operation Modes in a Five-Phase PMSM Considering Thermal Behavior
TypeCommunications avec actes
This paper presents a comparative evaluation of fault tolerant control strategies for a five-phase Permanent Magnet Synchronous Machine (PMSM) under an opened-phase fault mode. Two main classical Fault Tolerant Control (FTC) methods and the no-reconfiguration strategy are compared with the normal mode operation considering peak current, peak voltage, average torque, torque ripples and measured temperatures of five windings of the five phases. The analysis of the temperature repartition shows that, in fault mode, at least in the particular studied case, the knowledge of the Joule losses is not sufficient for a correct control of the temperature.

Homopolar Current’s Copper Losses Analysis for Different Modulations in Open-End Winding Five-Phase drives DOS SANTOS MORAES, Tiago José; SEMAIL, Eric; TRABELSI, Mohamed; ZAHR, Hussein (IEEE, 2018)This paper analyses the copper losses due to the homopolar current of a five-phase open-end winding machine supplied by a 10-leg inverter and a single DC voltage source. This topology can have non-null high frequency ...
ZAHR, Hussein; TRABELSI, Mohamed; SEMAIL, Eric; NGUYEN, Ngac Ky (2017)For a particular five-phase synchronous machine, this paper investigates the sensitivity of a vectorial control strategy on the required peak phase voltage whose value is fundamental for the choice of the DC bus voltage. ...
GONG, Jinlin; ZAHR, Hussein; SEMAIL, Eric; TRABELSI, Mohamed; ASLAN, Bassel; SCUILLER, Franck (2018)In the context of traction drives with required torque transient capabilities and a classically wide flux weakening speed range, this paper gives design considerations of a particular Double-Polarity (DP) five-phase machine. ...
OUENZERFI, Safouene; ZAHR, Hussein; TRABELSI, Mohamed; BOUBAKER, Riadh; SEMAIL, Eric; HARMAND, Souad (IEEE, 2019)Even if intrinsically a five-phase machine can work with one opened phase, thermal constraints (temperatures in windings and Permanent Magnets) impose to decrease the mean torque in faulty operation mode. In order to ...
