JMAG - Efficiency map generation

Описание: This presentation presents techniques of electromagnetic field analysis to simulate the behavior of the electric machine during driving. By means of co-simulation of finite element analysis and control/ circuit simulation, it is possible to simulate current waveforms at driving. Loss models such as play model and 1D FEA methods can not only improve the accuracy but also help visualize inside phenomena such as minor loops and skin effect of the steel sheet lamination. Finally, those techniques are applied to generate efficiency maps and aid in the evaluation of the motor over the operating range.
