JMAG Users Conference & Workshop 2019 in Strasbourg


We will be hosting the JMAG Users Conference in France.
The conference will be held over three days; the first day will be JMAG Users Conference, and Workshop will consist of the second day and the third day.
We will also hold training with a focus on JMAG features.
This will be a great opportunity to gain information on electromagnetic analysis technology trends, usage environments, and so on. Come join us!

October 15th, 2019 (Tuesday) JMAG Users Conference

Development planning of JMAG, Takashi Yamada, Jsol Corporation.
JMAG is constantly being worked on to achieve highly accurate and high-speed simulation. JSOL would like to share our progress from the past year including parallel solvers to accelerate speed as well as GUI improvements aiming for increased productivity of analysis workflow. Analysis technologies we are currently focusing on and our plans for incorporation will also be covered in this presentation. Design exploration is an important topic this year. This presentation will detail the present and future of JMAG.
Development and simulation of multiphase machines with JMAG, Mr KELLER, DAIMLER .
Using the new Control Circuit Function to implement complex Control algorithms. Focus on problems of developing a dual three-phase machine.
Development of Thin and High Torque Axial Gap Motor Using Soft Magnetic Powder Cores, Tatsuya SAITO, Sumitomo Electric Industries, Ltd.
Currently, radial motors using laminated steel sheets are the mainstream for motors, but the needs for automotive applications, miniaturization and higher output are increasing. For these trends, we have demonstrated that axial gap motors with soft magnetic powder cores are effective for thinning and high power output for radial motors of the same size. In this presentation we will introduce the latest situation of the development of softmagnetic powder core contributing to high performance of various motors including the above-mentioned motors and examples of application to motors.
3-D design of transverse flux machine, Rajesh KUMAR, Sheffield University.
High power electric machine design with JMAG, Aymen Ammar, Jeumont Electric
JMAG suite use within electrical machine development process, Mamy RAKOTOVAO, Valeo
Multiphysics and multi-domain approach is key when developing a new range of electrical machine. With JMAG software, we are now able to take into account in an accurate manner the most of critical development aspects when dealing with pre-design of the electrical machine, system integration, thermal constraints and noise issue. This is possible because this kind of software allows accurate losses and magnetic forces computation by handling very realistic electrical machine operation in various conditions such as actual control techniques, thermal impact on material characteristics and, of course, real machine drawing.
Accounting for AC loss in the electric machine design process using JMAG, Dave Winterborne, Höganäs AB research associate based at Newcastle University
Accounting for AC loss in the electric machine design process using JMAG In the case of electric machines operating at higher fundamental frequencies, additional losses due to skin and proximity losses – particularly in open slot designs – are significant and must be considered in the electromagnetic and thermal design of the machine. How can we use JMAG to incorporate this into an existing design methodology for SMC-based axial flux machines and produce accurate results without excessive computational cost?

Time Content
09:00-12:00 Principles of AC Machine Design, with Examples , Professor Tim Miller
The objective is to learn the straightforward principles of AC machine theory and to design three motors following classical methods of synthesis. The starting point is an induction (asynchronous) motor, which we will convert first to an interior PM motor, and secondly to a synchronous reluctance motor. By this means we will understand the differences between these machine types, and where these differences come from.


  1. Configuration and characteristics; classification, saliency, pole-number; sine-distribution of field and ampere-conductors
  2. Design example: specification
  3. Sizing; details of geometry and dimensions; magnetic and electric loading; current-density; rating
  4. Winding layout, including fundamental theory of winding factors
  5. Induction motor: design using conventional method of synthesis and equivalent circuit
  6. Brushless PM Motor: convert the induction-motor rotor to a PM rotor
  7. Synchronous reluctance motor: remove the magnets and create a pure reluctance motor
  8. Comparison of the three example motor designs
  9. Discussion of control characteristics and requirements

We don’t use any software in this short course, but most of the design examples can easily be repeated using JMAG Express. The examples are ready for further analysis using JMAG Designer, and some examples of finite-element calculations are included, giving additional insight into the designs.

12:00-17:00 Electrical Machine Technologies, Topologies, and Applications, Professor ZQ Zhu, University of Sheffield, UK
This presentation will start with the stator and rotor topologies of permanent magnet machines, with a focus on fractional slot machines. Then, the electromagnetic performance of alternate electrical machine technologies, i.e. induction machines, synchronous reluctance machines, and permanent magnet synchronous machines, will be compared for electric vehicle application. Recent development will be highlighted, including magnetic gears, magnetically geared machines, novel fractional slot and Vernier permanent magnet machines. The presentation will end with analysis, reduction and utilization of cogging torque in permanent magnet machines.
