• Magnetic field analysis/electromagnetic wave analysis

Aiming for low loss, accurately measure the actual state of electromagnetic materials and grasp and analyze their vector magnetic characteristics!

Iron loss evaluation, which has been a bottleneck in motor analysis. Conventional methods only consider iron loss as a function of magnetic flux density, resulting in low accuracy. However, accurately determining the magnetic field and magnetic flux density to calculate iron loss is achieved through "vector magnetic characteristic analysis." This allows for the calculation of high-precision distributions of magnetic fields, magnetic flux densities, and iron losses that are not achievable with other software. Vector magnetic characteristics refer to the properties that take into account the relationship between the magnetic field H and magnetic flux density B of electromagnetic steel materials, considering their direction (vector). The finite element method electromagnetic field simulator that incorporates this characteristic is “μ-E&S.” 【Features】 - High-precision calculation of magnetic field vectors is possible by considering vector magnetic characteristics. - Rotating magnetic fields and hysteresis can be calculated. - It is designed as an easy-to-use tool specifically for iron loss evaluation. *For more details, please request materials or view the PDF data available for download.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact to the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

SPACECOOL Co., Ltd. is pleased to announce that it will exhibit at the "Japan Pavilion" established by the Ministry of the Environment at the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30), which will be held in Belém, Brazil, from November 10, 2025. "SPACECOOL" is a radiative cooling material that enables zero-energy cooling by dissipating heat into space. At our exhibition booth, we will showcase examples of its use not only in reducing air conditioning energy in buildings but also in heat mitigation measures (adaptation strategies) for tents and parasols. The Japan Pavilion aims to promote excellent technologies, products, and services that support global decarbonization and adaptation to climate change, and to achieve Japan's long-term climate change goal of "net zero by 2050." We believe that our participation plays an important role in this endeavor. Through this exhibition, we aim to accelerate our initiatives with local partners in regions severely affected by heat issues, such as the Middle East, including Saudi Arabia and the United Arab Emirates, as well as Southeast Asia, contributing to global decarbonization and climate change measures.
