The analytical model for calculating electromagnetic force in the plunger model was set as a three-dimensional model.
The calculation of electromagnetic force in the plunger model was performed for the plunger model proposed by the Institute of Electrical Engineers for electromagnetic force verification, calculating the electromagnetic force acting on the center pole when current flows through the coil, as well as the magnetic flux density in various parts of the model.

basic information
【Features】 ○ The model is axially symmetric in both the X and Y directions. → Therefore, the actual analysis model is a 1/4 model as shown in Figure 2, based on that symmetry. ○ The total number of nodes in the model is 31,824, and the total number of elements is 28,900. ○ The module used for the analysis calculation is PHOTO-EDDY. ○ Material property conditions → Air relative permeability 1, coil relative permeability 1, magnetic material relative permeability 1000. ○ Analysis conditions → Coil current 1000AT. ○ Analysis results → Electromagnetic force acting on the center pole: 8.22N. The measured value presented by the Institute of Electrical Engineers is 8.23N, so the error can be said to be 0.12%, indicating a very accurate value obtained. ● For more details, please contact us or download the catalog.

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.
