Magnet eddy current loss calculation method for segmentation analysis on permanent magnet machines Madina, Patxi Poza, Javier Almandoz, Gaizka Ugalde, Gaizka AC machine Permanent magnet moto Synchronous motor electrical machine ODS 7 Energía asequible y no contaminante ODS 9 Industria, innovación e infraestructura ODS 13 Acción por el clima 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. In high power application usually it is necessary to design solutions to reduce eddy current losses. The most common technique is the magnet segmentation. Analytical calculation of magnet eddy current losses may give some inaccuracies on the results and FEM analysis may be too time-consuming in some design steps. A new method that combines FEM and numerical calculations to evaluate the losses for different magnet segmentation is presented in this paper. 2024-04-24T08:00:13Z 2024-04-24T08:00:13Z 2011 http://purl.org/coar/resource_type/c_c94f 978-90-75815-15-3 https://katalogoa.mondragon.edu/janium-bin/janium_login_opac.pl?find&ficha_no=76436 https://hdl.handle.net/20.500.11984/6364 eng © 2011 The authors IEEE
