Geometrical control of eddy currents in additively manufactured Fe-Si

Materials & Design, 2023
Additive manufacturing has enabled the processing of high silicon electrical steels which have excellent soft magnetic properties. In bulk form, core losses as a result of eddy currents would be too large to allow their use in high-frequency electrical ...

Impact of ocean resolution on coupled air-sea fluxes and large-scale climate [PDF]

, 2016
Air-sea fluxes are a crucial component in the energetics of the global climate system. The largest air-sea fluxes occur in regions of high sea surface temperature variability, such as ocean boundary, frontal currents and eddies.

Analytical modelling and analysis of magnet eddy current loss in magnet‐surrounded permanent magnet synchronous machine caused by stator slot effect

IET Electric Power Applications
To improve the machine torque density, this paper proposes a magnet‐surrounded permanent magnet synchronous machine (MSPMSM). As the critical material of MSPMSM, the permanent magnet (PM) will produce significant eddy current loss under the action of ...

A Study on Eddy Current Reduction Shape of Single-Phase Claw-Pole Motor

Actuators, 2023
The claw-pole motor, known for its simple structure, is widely used in various fields due to its cost competitiveness. However, a drawback of the fixed-stator-type claw-pole motor is its vulnerability to eddy current losses.
