Abstract:
This study is undertaken to highlight the competitive
optimal performance of permanent magnet flux
switching machines (PM–FSMs) in different wind generator
drivetrains––low–speed (LS), medium–speed (MS)
and high–speed (HS). The three–phase 12–stator
slots/10–rotor teeth PM–FSM is selected for the study, for
small–scale power applications. The design and optimisation
is performed using a 2–D finite element analyses
(FEA) tool. Thereafter, important features of the different
wind generator drivetrains are evaluated and compared,
especially in terms of cost of energy (CoE) versus performance.
In the end, the study barely stops short of representing
the MS as the best among the three drivetrains;
however, it is clearly a preferred solution due to trade–
offs in torque density and cost of generator.
