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:Richard Csaba Kovacs Vilmos 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 […]
