Electromagnetics PRESENTER:Cleef Thackwell EXPERTISE:Electromagnetics Software:JMAG In order to accurately predict the energy consumption of electrically-excited synchronous motors (EESM) for automotive applications, a fine resolution sweep of id,iq and if is required to generate the dataset used to find the optimum control set-point. PWM-effects on copper and iron losses must also be considered, especially at low-load […]

Electromagnetics PRESENTER:Dr. W. Hackmann EXPERTISE:Electromagnetics Software:JMAG Electrical machines in traction applications are operated in inverter-fed operation over wide speed ranges. The special demands on compactness and high efficiencies of those e-machines lead to high expectations on the FEA simulation accuracies. Here important aspects are described and a sequence of defined measurements for a proper correlation […]

Electromagnetics PRESENTER:Yiwen MA EXPERTISE:Electromagnetics Software:JMAG In this keynote presentation, we explore the challenges of simulating Axial Flux Machines (AFM) in high-speed traction drive applications using JMAG. The discussion will focus on the computational hurdles and resource-intensive nature of 3D simulations, in contrast to multi-layer 2D approaches. Special attention is given to the intricacies of calculating […]

Electromagnetics PRESENTER:Philipp MORITZ EXPERTISE:Electromagnetics Software:JMAG The trend towards higher voltages is omnipresent in modern drive systems. As a result, the demands on the materials and insulation systems of the winding system are also constantly increasing. With electrostatic 2 and 3D JMAG simulations, the electric field strengths in the slot, at the slot exit and in […]
