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 to analyze the changes in the surrounding magnetic field. 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.

Company information
At Photon, we are developing "electromagnetic field analysis software" that models and simulates products and components utilizing electromagnetic phenomena on computers. In traditional design and development environments, the process has primarily revolved around trial and error through prototypes based on the experience of engineers and experiments with those prototypes. However, conducting experiments with actual prototypes and analyzing the results requires significant time and cost. Moving forward, transitioning from an experimental and prototype-based approach to an analysis-based design is a critical issue for improving productivity, and establishing simulation technology as the core of analysis-based design techniques is a challenge. 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 reduce the number of prototypes and development costs, shorten development periods in the manufacturing sites of our users, and ultimately support the enhancement of our users' competitiveness.
