This study reports the analytical computation including performance characteristics such like load line voltage and output power in combination with coupled-field circuit analysis of a 4kW direct drive permanent magnet synchronous generator (PMSG) to be used in a micro-scale run-of-the-river-station application. The specifications such like slot opening, pole embrace and magnet length of PMSG are optimized by using parametric approach including multi-criterion design optimization. Based on the optimized design, the model has been exposed to some transient coupled-field circuit analyses based on variable river flow speed and variable ohmic load conditions. The analytical studies related to finite element methods and conducted parametric approaches verified the effectiveness of the employed dynamic co-simulations.
