Magneto-thermally Coupled Field Simulation of Homogenized Foil Winding Models
Silas Weinert, Jonas Bundschuh, Yvonne Späck-Leigsnering +1
Foil windings have, due to their layered structure, different properties than conventional wire windings, which make them advantageous for high frequency applications. Both electro…
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…
Thermal Model Calibration of a Squirrel-Cage Induction Machine
Leon Blumrich, Christian Bergfried, Armin Galetzka +4
Accurate and efficient thermal simulations of induction machines are indispensable for detecting thermal hot spots and hence avoiding potential material failure in an early design…
Thermal Finite-Element Model of an Electric Machine Cooled by a Spray
Christian Bergfried, Samaneh Abdi Qezeljeh, Ilia V. Roisman +3
The need for higher power density in electrical machines require better cooling strategies. Spray cooling is a very promising and relatively simple technology to apply, but involve…
