Using the analysis module "PHOTO-EDDY"! Analyzing the torque waveform during steady operation, taking into account the rotation of the rotor.
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 was referenced from the benchmark model (K model) of induction motors by the Electrical Engineering Society's Investigation Committee.

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.
