Real-Time Detection of Interturn Faults in PM Drives Using Back-EMF Estimation and Residual Analysis

, 2011
International audienceInterturn stator winding fault is one of the most frequent faults in permanent-magnet synchronous machines (PMSMs). In this paper, we present a new technique for online detection of this fault in PMSMs.

A Study on the Transient Performance of Compensated PLL-Type Estimators for Sensorless IPMSMs

Actuators
The transient performance of sensorless control for interior permanent magnet synchronous motors (IPMSMs), based on back-electromotive force (back-EMF) estimation, is a critical factor in ensuring the high reliability of motor drive systems.

A back-EMF threshold self-sensing method to detect the commutation instants in BLDC drives

, 2015
By predicting future phase-current commutation instances of brushless dc (BLDC) machines, self-sensing control is achieved. Detection of the back electromotive force (EMF) zerocrossing moments is one of the methods used to predict the phasecurrent ...
