The authors are currently investigating the use of bulk high temperature superconductors as trapped field magnets (TFMs) in order to increase the electrical and magnetic loading of an axial gap, trapped flux-type superconducting electric machine. In electric machines, the use of superconducting materials can lead to increases in efficiency, as well as power density, which results in reductions ...

1. Introduction Polycrystalline single phase materials often display electrical properties that are a function of their grain size. Impedance spectroscopy, an alternating current technique is ideal for detecting the presence of more than one current path and has been used for many years[1,2]. However, it is proposed here that it may be possible to use concepts developed for two phase ...

Energy efficiency and harvest, speed and performance, flexibility and portability are key elements for innovation in the current consumer electronics markets. Thermoelectric Generators can convert energy from heat gradients into electricity. Every source of heat from an electronics device can potentially be used as a source of energy. This generators have the advantage of: being silent, compact, ...

Impedance spectroscopy is a measurement technique that has been investigated in a wide variety of medical applications. An example is the measurement of the dielectric properties of the skin and underlying tissue using sensors placed in contact with human skin with capacitive fringing field electrodes. The aim of this work is to use finite element methods for optimizing the sensor design ...

Eddy current testing (ECT) is widely used to check the integrity of electrically conducting parts and notably to detect flaws. It is based on the interaction between a probe and the part under testing. The finite element method (FEM) is well fitted to the modelling of these kinds of problems because of its large flexibility which allows to deal with complex probe and part configurations. In this ...

This elaboration presents the Active Magnetic Suspension (AMS) and radial Active Magnetic Bearing (AMB) as a representative of the Active Magnetic Levitation Systems (AMLS). The laboratory test rigs are analyzed in the 2D space. The control algorithm as well as the motion dynamics are implemented directly in COMSOL Multiphysics. The discussion on features and limitations is provided to show an ...

Laminated media are intended to conduct the magnetic flux in the plane (high resistance to limit the eddy currents). When fringing flux falls in perpendicularly to the plane, the surface for the eddy currents is no longer small. This will cause eddy current losses, which will reduce the efficiency of the application. A 2D FEM model for in plane losses in laminated ferromagnetic media due to ...
