Check how the magnetic field distribution changes when the electrical conductivity, rotation speed, and position of the gears are altered!
When a magnet is brought close to a gear made of a magnetic material, the distribution of the surrounding magnetic field changes depending on the position and rotation speed of the gear. A permanent magnet was placed near the rotating gear, and the changes in the surrounding magnetic field were analyzed. As a result, in the comparison of magnetic flux density due to rotation speed, the gear rotating at high speed exhibited a larger magnetic field along the edge of the gear, and a magnetic field due to eddy currents remained even when it was away from the magnet. 【Case Summary】 ■ Analysis Type: 3D Nonlinear Transient Magnetic Field Analysis ■ Analysis Module: PHOTO-EDDY *For more details, please refer to the related links or feel free to contact us.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on a computer. In traditional design and development environments, the process has primarily revolved around trial and error through prototyping based on the experience of engineers and experiments with prototypes. However, conducting experiments using actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototyping-based approach to an analysis-based design approach will be a crucial challenge for improving productivity, and establishing simulation technology as the core of analysis-based design techniques will be essential. In this context, Photon is developing and providing "analysis software" focusing on electromagnetic fields, as well as heat, vibration, and sound fields. By utilizing Photon's software, efficient development and design of various industrial products can be achieved. In this way, Photon aims to support users in reducing the number of prototypes, lowering development costs, and shortening development periods in their manufacturing environments, ultimately enhancing their competitiveness.
