Non-destructive testing (NDT) team at the Solid State Physics Department of the Faculty of Applied Physics and Mathematics cooperates on the broad scale with industry representatives in developing methodology and apparatus for magnetic NDT.

Currently we are optimizing Pipeline Inspection Gauge (PIG) with Magnetic Flux Leakage (MFL) system to evaluate technical condition of pipelines. Such system consists of magnetizing yoke and magnetic field sensors. Working PIG can reach velocity of even 10 m/s due to liquid media pressure. Our job is to model effect of velocity on eddy currents generation and hence distortion of MFL signal.

We have heard about the EMWorks software as a result of searching for Finite Element Modelling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks. Thanks to this design of even very complex models becomes child's play. My first magnetostatic model in EMS was created in just a few minuts! I highly recommend EMWorks software for all those who need friendly interface as well as professional FEM software.

Revolve NTNU is an independent student organization at the Norwegian University of Science and Technology. The team consists of 50 members who work voluntarily parallel to full time engineering studies. The members are from over 10 engineering fields and all years of study.

To develop and build a race car from scratch in one year is a challenging task that demands numerous engineering fields, extraordinary dedication and hard earned resources. Every year a new team of students take on the complex and comprehensive project to make the transition from students to fully capable engineers. Our vision is “from theory to practice”. We believe the interdisciplinary teamwork and endless possibilities that the students face through a year in Revolve NTNU makes the project a perfect arena for personal development.

The University of California, Santa Barbara (commonly referred to as UC Santa Barbara or UCSB) is a public research university and one of the 10 general campuses of the University of California system. The main campus is located on a 1,022-acre (414 ha) site near Goleta, California, United States, 8 miles (13 km) from Santa Barbara and 100 miles (160 km) northwest of Los Angeles. Tracing its roots back to 1891 as an independent teachers' college, UCSB joined the University of California system in 1944 and is the third-oldest general-education campus in the system.



"I used the AC Magnetics module within the EMS software to model electromagnetic coupling to a lab-scale molten metal charge.  This modeling was meant to investigate the efficiency and efficacy of inductive coupling as a means to heat and stir a metal solvent for a high temperature crystal growth process.  I found the software to be well integrated with Solidworks, with intuitive menus and feature commands.  The array of parameters available for adjustment was quite broad; I was able to easily set up a good proxy for my actual experimental setup.  The ability to copy/paste an entire study in one step made it especially quick to vary parameters and compare results.

 

EMS software represents a powerful and robust tool for anyone conducting research, design or development of systems involving electromagnetics."  

The Silesian University of Technology (SUT) is one of the biggest universities of technology in Poland, with more than 60-years successful tradition in education, research and development as well as cooperation with industry. 



The Faculties cover the whole range of engineering disciplines, as well as elements of management, sociology and administration. The number of students in all types of courses in the academic year 2013/2014 is about 27 000. Educational and research activities benefit from large number of modern lecture halls and advanced laboratories and are carried out by remarkable university staff consisting of over 1700 academic teachers including 300 professors and DSc degree holders.



…”The installation of EMS for Inventor is very easy, it also has a lot of analysis options. The interface is intuitive and clear. EMS for Inventor allows for fast and accurate linkage analysis in the field of electro-thermal and magnetic as for the design of highly complex projects is very useful. EMS saves time and avoids the problems associated with the transformation of files between different programs - in this way we gain time, which in the case of very complex analysis is priceless. The Support Team of EMWorks is very professional and very helpful - if an error is detected; the reaction and giving solution is very fast…”

In our bachelor thesis, a patented “bifilar” coil (BC) type permanent magnet generator (PMG) is constructed for scientific research. The features, working principle and elements of the BCPMG are analyzed.

The BCPMG is developed from the iron-cored “bifilar” coil topology based on Aleksas Pašilis's and Eleonora Guseinovien's patent (Lithuania) in an attempt to overcome the problems with current rotary type Generators, which have so far been dominant on the market.

One of the problems is Armature Reactance, which is usually bigger than Resistance.

The circumstance creates difficulties for designers and operators of the Generator.

"...That is why patented technology is offered to partially remove or absolutely neglect the reactance of the machine. We used The Simulation Software EMS:

To get to the flow direction of the Magnetic Flux Densities through the system, which the same is as expected to be.

To test to a real machine. We found the opportunity of the motion simulation, but there wasn't much time for that investigation.

We have made only a 1/5 sector of the generator to keep the resources at minimum.

We used also a Finite Element Magnetic Model (FEMM) to visualize the effects of the system.

To visualize the effects of the 3 phase current to the flow of flux and densities on the system."
