Physical Modeling of Core Losses in Ferrite E-Cores

open access: yesIEEE Open Journal of Power Electronics
The development of advanced power electronic converters requires an accurate calculation of core losses in magnetic devices. But the losses in the widely used ferrite cores depend on the shape of the core, especially above 10 kHz, meaning that core ...

Core loss resistance impact on sensorless speed control of an induction motor using hybrid adaptive sliding mode observer [PDF]

open access: yesArchives of Electrical Engineering, 2023
Induction motors (IMs) experience power losses when a portion of the input power is converted to heat instead of driving the load. The combined effect of copper losses, core losses, and mechanical losses results in IM power losses.

Analysis of Modular Stator PMSM Manufactured Using Oriented Steel

open access: yesEnergies, 2021
Oriented steel has higher permeability and lower losses in the direction of orientation (the rolling direction) than non-oriented steel. However, in the transverse direction, oriented steel typically has lower permeability and higher losses.
