Comparative Behavior Study of Various PMSM Topologies Under Demagnetization Conditions

International Conference on Electrical Machines
To improve our understanding of permanent magnet synchronous machines (PMSM) fault behavior caused by local demagnetization faults, we propose in this article to study the influence of the machine topology on its electromagnetic harmonic behavior ...

Electromagnetic Performance Analysis of Asymmetric Hybrid-SPPMSM After Demagnetization Considering Nonlinear Demagnetization Curve

IEEE transactions on magnetics
The demagnetization fault of a salient-pole permanent magnet synchronous motor (SPPMSM) can reduce the motor’s output performance and load capacity, which can severely affect its service life.

Ultrafast Demagnetization Dynamics in Room-Temperature vdW Ferromagnet Fe3GaTe2.

Journal of Physical Chemistry Letters
Femtosecond-laser-induced ultrafast demagnetization in two-dimensional van der Waals (vdW) ferromagnets offers an ideal testbed for probing spin relaxation proximate to the Curie temperature (TC). Here we report a systematic time-resolved magneto-optical

Demagnetization field driven charge transport in a TiO2 based dye sensitized solar cell

Solar Energy, 2019
We report on the effect of demagnetizing fields due to magnetite (Fe3O4) nanoparticles (NPs) on the efficiency of TiO2 based dye sensitized solar cells (DSSC). The addition of Fe3O4 NPs into the photoanode enhanced the power conversion efficiency of DSSC.
