We will introduce general-purpose motor drivers and simulation models that support automatic code generation. In the exhibition, we will demonstrate motor drives using our products. The motors to be driven are an SR motor and a synchronous reluctance motor, both of which were designed and prototyped by Nagaoka motor development. Prototype motor models and simulation models will also be exhibited. We offer complete solutions from a single source, motor design, prototyping, and driving, so please stop by our booth for more information.

Advanced measurements and analysis for EV motors are introduced, which includes

• minute loss evaluation for motor cores and magnets
• disintegration analysis for EV motors
• stress measurement and its effect on magnetic properties
• noise and vibration, heat transfer and insulation measurement and correlation with CAE through magnetic analysis
• computer aided engineering for loss, heat, power, noise and vibration

In the evaluation of actual motors, it is necessary to measure several physical phenomena such as motor control current, heat and vibration with several individual measuring instruments, and it takes time to integrate these measurement data and check the correlation between them.
At the YOKOGAWA booth, we will demonstrate efficient motor measurement using the ScopeCorder DL950, a high-speed recorder, that can record current, temperature, acceleration, and angle calculation using encoder position sensors and real-time analysis of d-q current-voltage simultaneously, display and analyze them.

We will introduce system analysis that is effective for NV countermeasures in the upstream design of our solutions. In addition to the design index of torque value, which is an important characteristic of the motor itself, NV countermeasures are becoming more important as motors rotate at higher speeds, and we will solve your problems by utilizing 1D/3D analysis. We look forward to seeing you at our booth.

Denshijiki Industry presents the magnetization characteristics evaluation device BH-1000. The BH-1000 is ideal for obtaining hysteresis loops of various magnetic materials for magnetic field analysis. Magnetic fields can be set with the DC-biased magnetization properties option, enabling minor loop measurements and evaluation of simulated material properties under real-world conditions. We hope this will help in achieving more accurate magnetic field analysis. In addition, we provide a simplified measurement jig as an option for the BH-1000.

We UNIPULSE will introduce the rotating torque meter UTM series for characteristic evaluation such as cogging torque, torque ripple and efficiency measurement of actual motors analyzed and designed by JMAG.
With the high resolution of 1/10000 and the high-speed responsivity of 5kHz, UTM series can operate infinitesimal variance measurement such as cogging torque and torque ripple with high reproducibility. In addition, due to the design that keeps a mechanical loss low, UTM series are suitable for efficiency measurement as well.
UTM series can be utilized for wide range of sites from R&D to manufacturing.

We provide the development tools necessary for research and development in the power electronics field.
Coupled with JMAG, detailed motor models can be simulated.

DT-1063 is a motor HILS that can use motor models supported by JMAG-RT, and has a fast response speed of 2μSec for both the current output and angle output. The computational system is 32-bit floating-point arithmetic (IEEE-compliant), can also simulate inverter failure, and is reasonably priced. The development of other custom motor models (such as open-winding motors, double three-phase motors, and wound-field motors) is also supported.

Hewlett Packard Japan presents the ProLiant DL385 Gen11 server (with the latest AMD EPYC CPU) and the Z8G5 (with the latest Intel Xeon CPU) high-end workstation.

We look forward to welcoming all users who are interested in the latest trends in CAE infrastructure and those who are considering replacing their products.

The wave of electrification is accelerating toward the realization of Green Transformation (GX), which aims to decarbonize and transform economic and social systems. In the future, it will become increasingly important to efficiently evaluate the functions and performance of motor control systems and to speedily develop products. We will show the workflow of model-based motor control system development, including modeling and simulation (JMAG-RT collaboration) of physical phenomena and control algorithms, microcontroller implementation (TI C2000) of control algorithms using automatic code generation, and model-based calibration of flux-weakening control.

RecurDyn can implement high-fidelity NVH analysis for electrified driving systems composed of complex components such as gears, bearings, shafts, and external cases, coupled with cutting-edge electromagnetic simulation technology from JMAG.
JMAG can provide RecurDyn with precise information about excitation changes caused by motor torque ripple through CoLink or Matlab/Simulink.
This strong coupling will enable RecurDyn to perform various types of driving system analyses, ranging from small electric appliances to large machinery such as ground vehicles, airplanes, and ships. Furthermore, thanks to the versatile connectivity of the RecurDyn interface, the scope of system analysis can be greatly extended to many other applications, utilizing its interactive capabilities for structural analysis, fluid analysis, controls, and optimization.

In recent years, as AI is expected to be applied to development sites, surrogate AI as a substitute for CAE has started to be used in actual design sites, producing results in terms of speed-up and non-parametric geometry design.
Optimus can further enhance the value of surrogate AI as a CAE integration platform, offering new ways to utilise AI.
In the partner seminar, we will also introduce examples of collaboration between structural analysis using Ansys and electromagnetic field analysis using JMAG. We will have dedicated engineers at our exhibition booth, so please feel free to ask for them.

Motor Prototype making, Development and Engineering

SIMBA offers an easy and effective way to model and simulate complex motor control algorithms and control systems.

SIMBA’s Motor Drive library gives you the building blocks in order to save design time and drive complex power electronics-based motor control systems.

This library gives you access to a full complement of built-in motor models including Permanent Magnet Synchronous Motors (PMSM) and Squirrel Cage Induction Machine.

SIMBA provides also mechanical load models and speed/torque probes for monitoring purpose.
The use of C block allows to setup any complex control algorithms such MPTA (Maximum-Torque-Per-Ampere), Field Weakening Control blocks, and even more…
Motor Drive system includes multiple control loops such as current and speed loops.
In that sense, the use of the SIMBA python module allows to tune the control stage for designing the controllers of the motor drive system.

By using the SIMBA Python module “aesim.simba” any users can run some python scripts for optimization and automation purposes.
In this way, an interactive Efficiency map for motor drive systems could be developed in python language for having the efficiency of the inverter for example.

Welcome to our exhibition corner.
We at ARD CORPORATION provide high-performance workstations & clusters for Best performance on JMAG.

ECUs that control motors and inverters are becoming increasingly complex and require high-speed control. In this demo setup we present a HIL test environment for a motor ECU. The setup consists of a SCALEXIO real-time hardware system, with processor board, FPGA board, and IO boards and a plant model that simulates electric motor, inverter, battery and vehicle. The inverter gate signals are measured with high precision and used to calculate the motor currents and torque in real time by the motor model executed on the FPGA. The dSPACE XSG JMAG solution enables front-loading of ECU testing by reusing the simulation assets from the development phase.

In motor development, it is necessary to optimize heat and power consumption in electric vehicles.
