Homogenized harmonic balance finite element method for nonlinear eddy current simulations of fast corrector magnets
Jan-Magnus Christmann, Laura Anna Maria D'Angelo, Herbert De Gersem +5
This paper develops a homogenized harmonic balance finite element method (HomHBFEM) to predict the dynamic behavior of magnets with fast excitation cycles, including eddy current a…
A Dynamic Energy-Based Hysteresis Model for Pulsed-Operated Fast-Ramping Magnets
Dominik Moll, Laura A. M. D'Angelo, Herbert De Gersem +3
Due to the strongly nonlinear behavior of ferromagnetic yokes, the numerical analysis of fast-ramping magnets is highly cumbersome and, therefore, in practice overly simplified by…
Transient Nonlinear Electrothermal Adjoint Sensitivity Analysis for HVDC Cable Joints
M. Greta Ruppert, Yvonne Späck-Leigsnering, Herbert De Gersem
Efficient computation of sensitivities is a promising approach for efficiently of designing and optimizing high voltage direct current cable joints. This paper presents the adjoint…
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…
