Initially used only for small and medium powers the PMSG’s are now used also for higher powers (because of their already mentioned advantages). ![]() Introduction From all the generators that are used in wind turbines the PMSG’s have the highest advantages because they are stable and secure during normal operation and they do not need an additional DC supply for the excitation circuit (winding) –. Key words Synchronous generator, permanent magnet, simulation, optimization. The studies show that for certain values of these dimensions the magnetic flux (flux linkage and mutual flux) has maximum values. Keeping the same rotor diameter the generator’s magnetic flux is maximized by changing the permanent magnets and rotoric slot opening dimensions. The paper shows a 2D finite element optimization method for a wind turbine permanent magnet synchronous generator (PMSG) transverse geometry.
