A Review in Fault Diagnosis and Health Assessment for Railway Traction Drives
Garramiola, Fernando; Madina, Patxi; Andrade del Olmo, Jon; Almandoz, Gaizka (MDPI AG, 2018)During the last decade, due to the increasing importance of reliability and availability, railway industry is making greater use of fault diagnosis approaches for early fault detection, as well as Condition-based maintenance ... -
Analysis of non-uniform circumferential segmentation of magnets to reduce eddy-current losses in SPMSM machines
Madina, Patxi; Almandoz, Gaizka; Ugalde, Gaizka; Garcia Poza, Javier (IEEE, 2012)Eddy current losses generated in the rotor of the permanent magnet machines may lead to an excessive magnet heating. This can cause full demagnetization of the magnets so it is very important to analyze the losses on them ... -

Magnet eddy current loss calculation method for segmentation analysis on permanent magnet machines
Madina, Patxi; Poza, Javier; Almandoz, Gaizka; Ugalde, Gaizka (IEEE, 2011)Eddy current losses generated in the rotor of permanent magnet machines may lead to an excessive magnet heating. This can cause the magnets to get fully demagnetized so it is very important to analyze the losses on them. ... -
Metodología de diseño de motores síncronos de imanes permanentes para aplicaciones ferroviarias
Madina, Patxi (Mondragon Unibertsitatea. Goi Eskola Politeknikoa, 2013)The train traction, a mainly induction machine dominated sector, is leading towards smaller and more efficient machines in the last years. The permanent magnet machines meet the ideal characteristics in order to accomplish ... -
Multi-Physics Tool for Electrical Machine Sizing
Moreno, Yerai; Almandoz, Gaizka; Egea, Aritz; Madina, Patxi (MDPI AG, 2020)Society is turning to electrification to reduce air pollution, increasing electric machine demand. For industrial mass production, a detailed design of one machine is usually done first, then a design of similar machines, ...
