Linear electromagnetic devices — such as linear motors, generators, actuators, and magnetic gears — play a vital role in precision motion control, energy harvesting, and automation systems. Designing these devices requires a detailed understanding of electromagnetic field interactions, force generation, and thermal effects, all of which can be effectively analyzed using finite element analysis (FEA).
In this webinar, we will demonstrate how FEA tools such as COMSOL Multiphysics® can be utilized to model and optimize linear magnetic devices (motor and actuator) using the AC/DC Module and associated multiphysics interfaces. We will illustrate the complete modeling workflow — from geometry construction and material definition to coil configuration and magnetic field analysis — highlighting how we use the software to predict electromagnetic forces, flux linkage, cogging effects, and end effects unique to translational motion devices.
We will further show how parametric and optimization studies can be employed to refine key design parameters such as pole pitch, magnet thickness, air-gap length, and winding configuration. Through these analyses, we will demonstrate how to achieve the desired thrust, precise operation, and efficiency. We will also discuss coupled electromagnetic–thermal studies to evaluate temperature rise, losses, and magnet demagnetization under different loading conditions.
By the end of the session, participants will gain practical insights into how COMSOL Multiphysics® can be used to virtually prototype, analyze, and optimize linear machines, reducing development time and improving overall performance.
