This paper invetigates using the FEMLAB software modules in calculating the electromagnetic fields generated in the vicinity of High Voltage (HV) power transmission lines. The analysis presented in this paper is divided into two main parts. The first part investigate the effectivness of using the electrostatic and magnetotstatic modules of the FEMLAB software in claculating the generated ...

This paper reports a multiphysics analysis for a newly developed electromagnetic vibration absorber (EMVA). The EMVA uses an electromagnet, permanent magnet, and aluminum beam to form a variable spring. By changing the current of the electromagnet, the stiffness of the EMVA can be adjusted instantaneously. Such a device belongs to the family of tunable vibration absorbers. The tunable vibration ...

We are working on the design of a sounding rocket payload to perform high-resolution imaging spectroscopy of the Puppis A supernova remnant. This rocket payload uses Transition-Edge-Sensor Microcalorimeters, which are superconducting detectors that obtain very high (2 eV FWHM at 6 keV) imaging spectra. These devices need to be cooled to 50 mK, for which we are designing an adiabatic ...

Superconductors have the unique capability of trapping magnetic flux. This feature has the potential to enable and improve several applications including high power density rotating machines. Current material used as trapped flux magnets (TFM) is single domain YBCO that present numerous limitations interms of performance, stability and size. One way to overcome the limitations is to use thin ...

State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a distance to an approaching object. Capacitive sensing technology has proven to be an interesting alternative to ...

This paper shows how a time-dependent and non-linear simulation of the dynamic operation behavior of an induction machine is executed by means of the \"Rotating Machinery\" interface from COMSOL Multiphysics 4.2a. The two-dimensional FEM model is connected to electrical circuits by coupling the physics \"Rotating Machinery\" and \"Electrical Circuit\" interfaces. These circuits include the lumped ...

A simple proximity sensing circuit is made using magnets actuating reed switches; these switches are wired into a larger circuit that performs auxiliary functions. The success or failure of such systems is a function of their position. A simulation using COMSOL Multiphysics is conducted to study the position of a reed switch relative to a magnet when the switch opens and closes. Ability to ...
