McCann et al. presented two new transverse susceptibility techniques for experimentally measuring the demagnetization factor. Enabling comparison with experiment, these techniques are also applicable ...
Abstract: This paper investigates the demagnetization problem of permanent magnets for permanent magnet-assisted synchronous reluctance motors (PMa-SynRM) and applies “demagnetization ratio” as an ...
One of the most important PM machine faults in terms of occurrence rate is demagnetization fault, whose causes can be heat, electrical, environmental or combinations. This may lead to efficiency drop, ...
Within the last few years, the first testing devices have been launched that allow practical demagnetization of transformers on-site. When a transformer is re-energized, an inrush current occurs that ...
The phenomenon of ultrafast demagnetization 1, first discovered in 1996, resulting from excitation by an intense femtosecond infrared laser pulse, has been extensively investigated, yet its ...
Power-supply designers usually like flyback converters to operate in DCM (discontinuous-conduction mode) rather than in CCM (continuous-conduction mode). In DCM, the flyback converter is a first-order ...
