Efficient computation of eddy-currents for nonlinear magnetic field problems
Herbert Egger, Nepomuk Krenn, Andreas Schafelner
Estimation of eddy-current losses in conducting non-laminated components of electrical devices requires expensive three-dimensional simulations. Various approximations are therefor…
Isogeometric Topology Optimization Based on Topological Derivatives
Guilherme Henrique Teixeira, Nepomuk Krenn, Peter Gangl +1
Topology optimization is a valuable tool in engineering, facilitating the design of optimized structures. However, topological changes often require a remeshing step, which can bec…
Electro-thermal topology optimization of an electric machine by the topological derivative considering drive cycles
Nepomuk Krenn, Théodore Cherrière, Sebastian Schöps +1
We consider a 2d permanent magnet synchronous machine operating in a sequence of static operating points coming from a drive cycle. We aim to find a rotor design which maximizes th…
Multi-material topology optimization of electric machines under maximum temperature and stress constraints
Peter Gangl, Nepomuk Krenn, Herbert De Gersem
The use of topology optimization methods for the design of electric machines has become increasingly popular over the past years. Due to a desired increase in power density and a r…
Robust Topology Optimization of Electric Machines using Topological Derivatives
Peter Gangl, Theodor Komann, Nepomuk Krenn +1
Designing high-performance electric machines that maintain their efficiency and reliability under uncertain material and operating conditions is crucial for industrial applications…
