Analytical model to calculate radial forces in permanent-magnet synchronous machines
(IEEE, 2014)
In permanent-magnet synchronous machines (PMSMs) electromagnetic forces are identified as the principal source of vibrations and noises. In this article, first of all the sources of magnetic forces in PMSMs are analyzed. ...
Analytical model to calculate magnetic flux density in permanent magnet synchronous machines with static eccentricity
(IEEE, 2016)
In this article a general analytical model for the analysis of permanent magnet synchronous machines with static eccentricity is presented. The model is a continuation of [1] and it is based on Fourier time-space series ...
Radial fan simulations by computational fluid dynamics and experimental validation
(IEEE, 2014)
Fans are commonly used to refrigerate electrical machines when air forced cooling is required. They are rather simple solutions that can considerably improve the thermal performance of electrical machines, so the fan ...

Magnet eddy current loss calculation method for segmentation analysis on permanent magnet machines
(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. ...
