Core Losses in Claw Pole Permanent Magnet Machines with Soft Magnetic Composite Stators [PDF]
, 2003 This paper presents the core loss calculation in soft magnetic composite (SMC) samples and a claw pole permanent magnet machine with SMC stator. By using finite-element analysis of the magnetic field, the total core loss is computed by separating the ...

Nondestructive testing of metallic cables based on a homogenized model and global measurements [PDF]
, 2010 We propose a simple, quick, and cost-effective method for nondestructive eddy-current testing of metallic cables. Inclusions in the cross section of the cable are detected on the basis of certain global data: hysteresis loop measurements for different ...

Modelling and Test of an Integrated Magnetic Spring-Eddy Current Damper for Space Applications [PDF]
Actuators, 2021 We present the design, manufacturing, and dynamical characterization of a mechanical suspension made by a passive magnetic spring and an eddy current damper integrated into a single device. Three configurations with 2, 3, and 4 permanent magnets axially distributed with opposite polarizations are designed, simulated, manufactured, and tested. Stiffness

Reconnection Studies Under Different Types of Turbulence Driving [PDF]
, 2012 We study a model of fast magnetic reconnection in the presence of weak turbulence proposed by Lazarian and Vishniac (1999) using three-dimensional direct numerical simulations. The model has been already successfully tested in Kowal et al.
