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 […]

Electromagnetics PRESENTER:Mohamed Essam Ahmed EXPERTISE:Electromagnetics Software:JMAG The study covers coupled optimization of active electromagnetic components (such as magnets, copper, and lamination) and passive electric components (e.g., insulation paper, winding coating and wedges) in electric machines. The insulation system of the electric machine acts as an EMC transfer path that influences electromagnetic compatibility and safety as […]

Electromagnetics PRESENTER:Joel Wenger EXPERTISE:Electromagnetics Software:JMAG The design process for these efficiency and power-density driven optimizations is very evolved and highly application specific. For electric machine optimization, JMAG Designer, and especially the scripting capability, plays a crucial role in our design process. Related technical presentations

Electromagnetics PRESENTER:Richard Csaba KovacsVilmos Paiss EXPERTISE:Electromagnetics Software:JMAG If d-q model and FEM Coil Inductance methods are not feasible to determine the proper inductances of synchronous machines, then the differential inductance must be calculated directly. The differential self- and mutual inductances can be derived by stored energy methods. This presentation shows how the required inductances can […]
