Torsional Vibration Analysis of an electric-drive powertrain via system simulations with Simcenter Amesim and JMAG-RT

Modeling and simulation of Torsional Vibration Analysis of electric drive is largely done using a suit of 3D simulation tools. However, for some aspects, system simulation can support and provide answers quickly and efficiently. In this talk we will present the 1D Simcenter Amesim, a multi-physic simulation tool, in combination with JMAG-RT to address relevant use case of the TVA of an electric drive.

A Multidisciplinary Approach to Integrated Motor Modeling using GT-SUITE and JMAG

As electric vehicles become increasingly more mainstream, an increasing level of refinement is required for a modern driving experience. As efficiency and NVH targets become increasingly more stringent, an integrated CAE modeling approach is required to predict system behavior early in the development cycle. This integrated CAE approach requires multi-disciplinary modeling, of electromagnetics, mechanics, and thermal systems together. While these analyses may typically be managed by different engineers, or even different departments, there is a growing need for increased collaboration. This presentation will detail several avenues for increased collaboration of motor integration to improve NVH behavior.

Improvement of IPM motor performance by applying the new Si gradient steel sheet “JNRF”.

In recent years, from the viewpoint of motors downsizing, as the motor drive frequency increases, it has become necessary to reduce iron loss in the high frequency range and improve magnetic flux density in electrical steel sheets used as core materials.
Therefore, we have developed a new Si gradient steel “JNRF”. In this presentation, we will report the results of motor efficiency analysis when a new material “JNRF” is applied to the IPM motor.

FUJITSU Supercomputer PRIMEHPC FX1000 / FX700 and progress of JMAG porting on PRIMEHPC

Supercomputer Fugaku jointly developed by RIKEN and Fujitsu
ranked No.1 again in four HPC performance ranking in November 2020.

Using the same Arm based A64FX CPU as Fugaku,
FUJITSU Supercomputer PRIMEHPC FX1000 is high-performance, highly scalable yet very reliable supercomputer for extremely large-scale systems
and FUJITSU Supercomputer PRIMEHPC FX700 is an easily deployed model in the PRIMEHPC series based on standard technology

We also introduce the status of porting activities of JMAG on FX1000 and the plan of evaluating JMAG on Fugaku, which we are currently collaborating with JSOL.

Recent update of electric machine thermal management with CFD How to employ the oil cooling method (pros and cons)

Electromagnetic analysis by JMAG is recently getting improved at speed and accuracy.
To apply such results to the multiphysics simulation, those, of course, should be high fidelity.
For instance, if JMAG gets detailed loss distribution, the thermal analysis should build a detailed cooling methodology.
This seminar will present the recent CFD analysis updates for motor thermal management with oil cooling presented by siemens at the JMAG user conference 2018.

Introduction of IDAJ’s electromagnetic analysis service and various examples by JMAG.

Recently, it has become common to use electromagnetic field analysis in the design of electrical equipment to reduce the development time of products with fewer prototypes.
However, many JMAG-Designer users are suffering from a lack of “effective utilization technique of electromagnetic field analysis”, like due to a poor understanding of the underlying physical phenomena.
In this seminar, we will introduce the IDAJ electromagnetic field analysis service by explaining examples for various applications.

Cooperation between JMAG and MSC products in motor CAE

In recent years, the use of motors has been increasing in many industries including the automobile industry.
The primary purpose of CAE for motors is to pursue efficiency, but in order to evaluate performance, it is necessary to solve the problems of heat and noise. These problems can be solved by linking JMAG, and MSC Software’s thermo-fluid analysis software scFlow and acoustic analysis software Actran. Introducing examples of collaboration between JMAG and scFlow, and JMAG and Actran.
