Thermal analysis of the transmission torque in a slotted axial eddy-current magnetic coupling

This study investigates the transmission torque characteristics of a slotted axial eddy-current magnetic coupling with a particular focus on the thermal effects influencing its performance. The coupling design incorporates a novel combination of Magnetic Equivalent Circuit (MEC) modeling and Finite Element Method (FEM) simulations to analyze the thermal distribution and its impact on torque transmission efficiency. The results highlight the critical role of eddy current losses and thermal dissipation in determining the operational efficiency of the coupling. Key findings demonstrate that optimizing the material properties and slot geometry can significantly enhance thermal performance while maintaining high torque density. These insights provide a framework for designing advanced magnetic couplings with improved thermal and mechanical stability, suitable for high-power industrial applications.
