Abstract:

Is frictionless braking possible? Let’s discover this interesting topic more in detail! This seminar will discover an analytic coupled magneto-thermal analysis of an axial-flux (AF) permanent-magnet-assisted (PMA) eddy-current brake (ECB) at high-temperature working conditions. With its unique structure, AF-PMA-ECB has enhanced braking torque production capability as to conventional ones. However, the topology will make the construction vulnerable at high operating temperatures simply because the magnet properties and the brake capability are strongly dependent on temperature. Such problems require complex coupled multiphysics computer software-based finite-element analyses to obtain the actual brake performance. The proposed approach offers a simple and effective solution that consists of magnetic and thermal models, which are coupled to each other in the time domain. With the proposed method, the analysis time is reduced to minutes instead of days. Please join the seminar to discover this interesting topic!
