Eddy current losses in passive magnetic bearings

Journal of Applied Physics, 2002
Passive magnetic bearings built with permanent magnets, such as NdFeB (neodynium–iron–boron) or SmCo (samarium–cobalt), are very reliable systems when used for industrial applications such as centrifuges or flywheels, as they do not require any electromagnetic coil supply. Nevertheless, during the rotational motion, gyroscopic effects (like precession)

Eddy current losses in open-type cores

2022
• Purpose: The aim of this paper is to present a methodology for calculating eddy current losses in the core of a single-phase power voltage transformer, which, unlike a standard power transformer, has an open-type core (I-type core). In those apparatus, reduction of core losses is achieved by using a multi-part open-type core that is created by ...

Eddy-current losses in thin ferromagnetic sheets

Proceedings of the IEE Part C: Monographs, 1958
In very weak fields, the eddy-current losses in a lamination may be calculated exactly but the observed loss is always somewhat greater. Most of this extra loss varies with frequency and field in the same way as eddy-current loss, and if a quantity η equal to the ratio of the observed to calculated loss is defined it is found that it increases rapidly ...

Eddy current losses of permanent magnet motors

IEE Proceedings - Electric Power Applications, 1994
A simple and effective method for calculating the core eddy current losses in permanent magnet motors is presented. It uses the back EMF per tooth induced in the stator windings by the rotation of the permanent magnets. The eddy current losses of the stator yoke can also be evaluated as a function of the back EMF per tooth waveform.
