Structural, Dielectric, and Magnetic Properties of NiZnCu Ferrites Synthesized by Reactive Spark Plasma Sintering Process

Conventional methods for preparing ferrites are time-consuming processes, which require high temperatures in the order of 1200°C . The reactive spark plasma sintering method is a more rapid procedure involving lower temperatures. Different…

Rotational magnetic losses in non-oriented Fe-Si and Fe-Co laminations up to the kHz range

Literature data on the energy loss behavior of steel sheets under rotating induction are restricted to quite low frequencies, i.e. up to a few hundreds of hertz. This is not sufficient to predict the loss in high-speed electrical machines, where…

Closed-Loop Analysis and Control of Cavity Shear Layer Oscillations.

This paper focuses on the closed-loop control of an incompressible flow past an open cavity. We propose a delayed feedback controller to suppress the self-sustained oscillations of the shear layer. The control law shows robustness to changes in flow…
