The electromagnetic steel sheet uses a B-H curve equivalent to 35A300! The benchmark model adopts a concentrated winding stator.
IPM motors have a structure in which magnets are embedded in the rotor, allowing for the utilization of both magnetic torque and reluctance torque, making them widely used as high-efficiency motors. In this analysis, we examined the induced voltage in an unloaded state and the torque waveform under load conditions. The magnets are input with a magnetization vector, and the coil current is input as current density. The current density is set with a time point sequence of a three-phase AC waveform. By setting the rotational speed at the nodes that make up the rotor, we take rotation into account. 【Case Overview】 ■ Analysis Type: 2D Nonlinear Magnetic Field Analysis ■ Software Used: PHOTO-MAG *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 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.
