Investigation of Inner/Outer Rotor Permanent Magnet Flux Switching Generator for Wind Turbine Applications

In this paper two permanent magnet flux switching generator (PMFSG) is designed for 2 kW output power and 220 V phase voltage at 1500 rpm and comparatively analyzed for wind turbine applications. Both PMFSG share same C-core stator connected back-to-back through flux bridge (<inline-formula> &...
