Finite Element Method based Investigation of IPMSM Losses

M. Schmidtner [1], C. Markgraf [1], A. Frey [1],
[1] University of Applied Sciences, Augsburg, Bavaria, Germany

INTRODUCTION: This paper investigates the design of IPMSM as drive motor for an electric race car in the competition called Formula Student. A key parameter for electrical motor is the power density which is very important for the performance of such race vehicles [1] to keep the overall ... Read More

A Plasma Torch Model

B. Chiné [1],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica

Plasma torches are used in processing of materials and in energy industry for producing plasma. In this work we use the Equilibrium DC Discharge physics interface of COMSOL Multiphysics® to model a DC non- transferred arc plasma torch, under hypothesis of local thermodynamic equilibrium. ...

Meshing Challenges in Simulating the Induced Currents in Vacuum Phototriode

S. Zahid [1], P. R. Hobson [1],
[1] Brunel University London, London, United Kingdom

Vacuum phototriodes (VPT) have been used as photodetectors for many years in particle physics experiments. For example, they were used in the OPAL experiment at LEP and are currently used in the endcap Electromagnetic Calorimeter of the CMS experiment, at CERN’s Large Hadron Collider. ... Read More

Determination of NFC-Antenna Operating Distance by COMSOL Multiphysics® Simulation of Planar Transformer Modeling

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH, Espelkamp, Germany

Although the Near Field Communication (NFC) concept has been developed for the short distance communication between the NFC-reader antenna and transponder/Tag, yet the requirements of different Automotive OEMs vary drastically. For instance, for the keyless entry into the car based on ... Read More

Predicting the Parasitic Forces in the Magnetically Levitated Adaptive Optics Mirrors

C. Del Vecchio [1], R. Briguglio [1], A. Riccardi [1], M. Xompero [1],
[1] National Institute for Astrophysics, Arcetri Astrophysical Observatory, Florence, Italy

In an Adaptive Optics system, the magnetic coupling of the Deformable Mirror with the Reference Frame may generate undesired forces and torques when any mechanical misalignment occurs. Moreover, the concave or convex shape of the thin, adaptive mirror shell undergoes similar permanent ... Read More

Innovation of Combustion Particle Control Technologies Assisted by Numerical Modeling

D. Rubinetti [1],
[1] Institute of Biomass and Resource Efficiency, University of Applied Sciences and Arts Northwestern Switzerland, Windisch, Switzerland

Worldwide efforts to promote the use of renewable energies include combustion-based technologies that produce substantial amounts of pollutants. In order to control the environmental impact a proper treatment of exhaust gases is required. This study describes the development of a ... Read More

Nonlinear Shielded Multipair Twisted Railway Cable Modeling with COMSOL Multiphysics®

Y. Jin [1], G. Papaiz Garbini [1], S. Karoui [1], M. Cucchiaro [1],
[1] SNCF Réseau, Paris, France

Signaling and telecommunication cables are shielded multipair twisted cables that lie along the railway and transfer railway information at low frequency (some kilohertz). Due to the electromagnetic disturbance of the railway environment, coming from high voltage conductors such as the ... Read More

Simulation of an Impulse Arc Discharge in Line Lightning Protection Devices

A. Chusov [1], E. Rodikova [2], D. Belko [1],
[1] Streamer Electric Inc., Saint Petersburg, Russia
[2] Streamer Electric Inc. and Saint Petersburg State University, St. Petersburg, Russia

Line lightning protection devices (LLPD) nowadays are widely used for lightning protection of overhead power lines. LLPD is composed of electrodes in series embedded in silicone rubber which all together forms sequence of spark gaps. When lightning overvoltage is applied it causes ... Read More

Analysis of Electromagnetic Behavior of Permanent Magnetized Electrical Machines in Fault Modes

M. U. Hassan [1], R. Nilssen [1], A. Røkke [2],
[1] Department of Electrical Power Engineering, NTNU, Trondheim, Norway
[2] Rolls Royce Marine AS, Trondheim, Norway

The use of Permanent Magnet Synchronous Machines (PMSM) as shaft generators is not new in marine vessels propulsion drive trains. Due to risk of fires in stator windings by internal faults, DNV GL requires the shaft generator to be electrically dead without losing propulsion. This ... Read More
