Using the analysis module "PHOTO-EDDY"! Considering the rotation of the rotor, analyzing the torque waveform during steady operation.
Induction machines that utilize electromagnetic induction are used in home appliances, escalators, and trains. Since eddy currents flow in induction machines, magnetic field analysis is necessary. The subject is a squirrel-cage three-phase induction motor, and considering the rotation of the rotor, the torque waveform during steady operation is analyzed. The analysis model is based on the benchmark model (K model) for induction motors from the Electrical Engineering Society's investigation committee. 【Case Overview】 ■ Analysis Type: 2D 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.
