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 ... En savoir plus
The paper presents the results of the experiment consisting in determination of the influence of the magnetic field on deformations of the stator and the rotor of the DC motor. The numerical model of the motor for the frameless DC machine of the G series has been elaborated. Real ... En savoir plus
In this work, the process of micro-channels in electrochemical micro-milling by using rotating magnet assisted helical tool is presented. The results show helical tool and Lorentz force of the rotating magnetic field that enhance the renewal of the electrolyte and machining efficiency. ... En savoir plus
Surface plasmon polaritons (SPPs), which are confined along metal-dielectric interfaces, have attracted great interest in the area of ultracompact photonic circuits due to their strong field confinement and enhancement. COMSOL Multiphysics is an efficient and powerful software package to ... En savoir plus
Diffuse Optical Tomography (DOT) uses Near Infra-red (NIR) light to monitor physiological changes in internal organs. NIR light being less energetic in nature can be used for continuous monitoring of tumor infected biological tissue, neonatal brain and many such applications where high ... En savoir plus
Superparamagnetic nanoparticles have a wide range of applications in modern electric devices. Recent developments have identi fied them as components for a new type of magnetoresistance sensor. We propose a model for the numeric evaluation of the sensor properties. Based on the solutions ... En savoir plus
Different configurations of MEMS based accelerometer has been made and analysed using COMSOL Multiphysics.

The article presents the process of verification of the passive magnetic bearing by the Comsol Multiphysic program. There is shown construction of the radial passive magnetic bearing PMB60x85x20-5, which was designed in the Military University of Technology. The distribution of the ... En savoir plus
In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not ... En savoir plus
The field quality requirements of most particle accelerator magnets are very tight and, therefore, very precise simulations are needed to accurately calculate these devices. CERN\'s ROXIE code is widely used as a reference software to calculate normal conducting and superconducting ... En savoir plus
