April 24th Event: MATLAB JMAG Integrated MBD Solution Seminar - Achieving Front-Loading with Domestic Manufacturer's Toolchain -

We significantly lowered the cost barrier for MATLAB-compatible RCP that can be tested with research budgets.

The "DT-0009 RTSim-IV" is a simulator that allows real-time execution of control models created in MATLAB/Simulink. It achieves a simulation cycle of 20μs without using an FPGA and can independently control a total of 12 channels of PWM. It offers an overwhelmingly low price as a MATLAB-based RCP. Additionally, the carrier wave of the PWM generator can be a triangular wave or a sawtooth wave. The carrier frequency can be changed during simulation and can be set for each PWM output. 【Specifications (excerpt)】 ■CPU: ARM Cortex-A9 800MHz dual-core processor ■Memory: 1GB DDR3 SDRAM ■A/D: 100ksps 12bit 4ch (0-4.096[V]) ■D/IO: Input: 16bit, Output: 16bit ■PWM: 12ch (3-phase upper and lower arms x2), maximum carrier frequency 1MHz *For more details, please refer to the PDF document or feel free to contact us.

Standard equipped with a rental-compatible JMAG-RT compatible inverter failure simulation function! High precision and high-speed response capable motor HILS.

The DT-1063 motor signal generator is a motor HILS that allows for safe evaluation of controllers without the need for actual motors. It is a real-time simulator (motor HILS) compatible with the electromagnetic field analysis software JMAG developed and sold by JSOL Corporation. By loading JMAG-RT as the simulation model, it operates as a virtual inverter and motor. The compact box contains all the necessary systems for motor simulation and operates as a virtual motor with just a power supply. Additionally, it can be offered at about one-tenth the price of conventional products, making it possible to implement low-cost solutions for development departments aimed at mass production, such as outsourcing to external development partners. 【Features】 - Standalone independent system - Reasonable pricing - High-speed simulation - No advanced modeling technology required *For more details, please download the PDF or feel free to contact us.

"Front-loading" realized with the high-speed circuit simulator Scideam, equipped with a SiC/GaN device model, enabling loss analysis.

We would like to introduce Scideam, a domestic high-speed circuit simulator equipped with a SiC/GaN device model. It provides a comfortable simulation environment through over 25 years of historical computational algorithms and newly developed circuit editors and waveform viewers. By utilizing it in the early stages of development, you can preemptively eliminate factors such as specification failures and defects, thereby reducing design time and costs. This enables the realization of what is known as "front-loading."

Verification of whether failure detection during inverter malfunction can be performed within the detection time (within 100 ms).

This document verifies whether a failure can be detected within 100 ms of the occurrence of an open fault in the U-phase upper arm. Failure detection is determined by extracting components of fourth order or higher from the current waveform using a high-pass filter. 【Contents】 ■ System Configuration ■ Controller Specifications ■ Motor Specifications ■ Verification Details ■ Verification Results ■ Discussion *For more details, please download the PDF or feel free to contact us.

Recently, fine bubbles, which are tiny bubbles smaller than 100 μm and are referred to as "fine bubbles," have attracted attention in various fields such as the environment, agriculture, food, fisheries, and medicine, due to their ability to impart various functions to liquids. Fine bubbles are classified into two types based on their size: microbubbles and ultrafine bubbles. Recently, there has been a growing interest in ultrafine bubbles, which have a lifespan of several weeks to months. However, listening to the voices of researchers and users reveals some skepticism, which has become one of the issues hindering the spread of fine bubble technology. On the other hand, we have challenged the elucidation of the stabilization mechanism of ultrafine bubbles from a new perspective by enabling the control of number density exceeding 10 billion particles/mL without pressure or concentration operations using our ultrafine bubble generation technology. In this seminar, we will provide a fundamental explanation of fine bubble technology, including the basic physical properties, characteristics and functions, device technology, measurement and evaluation methods, and case studies, to promote research and utilization of fine bubbles based on a correct understanding.

Sekiguchi Iron Works Co., Ltd. will exhibit at the "Minami-Shinshu Environmental Messe 2025" held at S-Bird in Iida City, Nagano Prefecture. This exhibition will be held simultaneously with the "Environmental Industry Trade Fair" taking place the day before. It will be held over the weekend, with many family-friendly events planned. We encourage those who usually find it difficult to visit to take this opportunity to come. Our product exhibition area is located about 10 minutes from the venue.
