Veryst was pleased to participate in this free, online event which took place on Thursday, February 9, 2023. Dr. Nirmal Paudel provided the keynote address and spoke about "Electromagnetic Modeling and Design of Magnetic Couplings."
Magnetic couplings are electromagnetic devices that are used to transmit torque from a primary driver to a load without any mechanical contact. Unlike mechanical couplings, magnetic couplings are self-protected against overload (pull-out torque) and can tolerate shaft misalignments.
There are a variety of magnetic coupling topologies available, such as face-to-face, coaxial, tubular, and planar. Though these devices are different in their construction, one can use a common finite element analysis (FEA) modeling approach for their design and analysis.
In this keynote presentation, Dr. Paudel demonstrated a workflow for designing a magnetic coupling using COMSOL Multiphysics and its parametric sweep functionality. He showed how to design the magnets, model nonlinear magnetic materials, assign the motion using the Lorentz term, and incorporate the dynamic motion in various physics interfaces in COMSOL Multiphysics. He also demonstrated both static and transient simulations using models from academic literature.
