Permanent magnets synchronous machines faults detection and identification

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
The reported work is the design of a Fault Detection system for permanent magnet synchronous machines (PMSM). Two main faults occurring on these machines are identified as inter-turns short-circuits and rotor single pole demagnetization, and characterized. An analytical model of the PMSM is developed and simulated using Matlab Simulink.

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies

FEBS Open Bio, EarlyView.
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Current Tracking Adaptive Control of Brushless DC Motors

International Journal of Adaptive Control and Signal Processing, EarlyView.
In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Rotor demagnetization effects on permanent magnet synchronous machines

Energy Conversion and Management, 2013
Abstract The effects of asymmetrical magnet faults on the rotor of Permanent Magnet Synchronous Machines (PMSM) are analyzed in the present work. Two different stator winding configurations, series and parallel connected windings, are considered in the analysis.
