FEM based model development and co-simulation of automotive multi-phase claw-pole alternator and rectifier

The current publication introduces a FEM software based developed six-phase claw-pole alternator model. A model of power electronics has been built as well. The FEM model of the claw-pole alternator was co-simulated with the model of the power electronics. The FEM model was developed based on measurements of a real claw-pole alternator. In order to determine geometries and dimensions of components of the electrical machine, the examined claw-pole alternator was disassembled after electrical and mechanical measurements and various tests have been proceeded.
