Magnetic couplings can be used to transfer torque from a dry to a wet environment without the need for shaft sealings that wear out and, in the end, need replacement.

During this webinar, Flemming Buus Bendixen, senior magnet specialist at Sintex, will discuss how to optimize the design of magnetic transmissions, considering geometric dimensions such as the air gap between the permanent magnets and the separator can. Parameters and figures of merit like the pressure and harshness of the operating environment, eddy current losses, power losses, can losses, and critical temperature are also considered.

Multiphysics simulation results are so accurate that Sintex considers them a substitute for physical prototypes. In fact, magnet experts turn their high-fidelity models into simulation apps that are deployed to their colleagues in other departments and customers. While simulation experts dedicate their time to new projects, colleagues and customers can quickly and independently develop custom coupling solutions, being sure that their results are accurate.

The webinar includes a live demo in the COMSOL Multiphysics® software during which the modeling of a magnetic coupling is shown and simulation results such as losses, maximum torque, and temperature distribution are analyzed. Calculations and measurements on different systems as well as new, creative, and innovative solutions from the R&D department at Sintex will be also discussed. The webinar concludes with a Q&A session.
