The poster session that has received high praise each year will once again be held at the JMAG Users Conference 2009. We look forward to a technological exchange related to the development concepts presented for JMAG this year.

The next version of JMAG, version 11, is being developed focusing on the concept of a virtual test bench (VTB). Those that attend the poster session will get a first look at the design concepts for JMAG version 11 introduced by the JMAG engineers and participants will be invited to share their opinions and ideas of those concepts that are presented so that JMAG can reach an even higher standard of quality.

Before outlining version 11, let us review the previous development concepts that have been the foundation for the development of JMAG.

Driven by the concept of creating a universal electromagnetic field analysis software, JMAG’s development has striven to implement and improve thermal, structural, and magnetic field analyses as well as a coupled analysis function used to combine these different types of analysis functions centered on electromagnetic field analyses. JMAG has successfully expanded the regions that can be applied while increasing the details the analyses can provide.

The know-how of the users has been indispensable in providing unique feedback related to combining the vast number of functions and analysis regions that JMAG offers to meet analyses and evaluation needs.

Version 11 aims to provide steps and methods to comprehensively analyze and evaluate electric devices based on the users experience and needs when evaluating phenomena.

For example, to evaluate the winding temperature of an IPM motor, first the drive condition necessary to evaluate the winding temperature is specified, the losses that cause the heat are calculated while accounting for the stress that affects the losses. This procedure will be preformed by simply selecting settings based on the accuracy required for an analysis in version 11.

The concepts presented via the posters introduce a virtual test bench that is based on specific applications, such as motors, transformers, and induction heating devices, as well as the items that can be evaluated. These posters aim to spark a rich technical discussions where participants can offer options and review the work of the JMAG Engineers.

More detailed information about the JMAG Users Conference 2009, such as the schedule, will continually be updated.

Frequently Asked Questions

Q1. Version 11 is used from the perspective of application, but will I still be able to use the functions as I did in version 10?
A1. Yes. Version 11 can be used in the same way as Version 10.

Q2. Will new functions be added for the solver and mesh in version 11?
A2. Absolutely. In addition to implementing and improving functions that are application specific, speed of the solver and the accuracy and speed for generating mesh will be enhanced for all of the analyses in JMAG.
