WebFirst, the finite element method is used to establish the 2-dimensional (2D) model, and then the ANSYS software is applied to simulate the calculation. Finally, the results of eddy current brake force (i.e., horizontal braking force) and the normal force change with speed are obtained. We did the analysis on the simulation results, which were ... WebMar 6, 2024 · Less energy efficient (but still better than mechanical braking) is the use of eddy current braking. With eddy current braking, all generated electric energy is converted directly into heat. Since the energy conversion takes place without mechanical contact, these systems tend to be much more robust than friction-based systems.
