SLOTLESS, TOROIDAL WOUND, AXIALLY- MAGNETIZED PERMANENT MAGNET GENERATOR FOR SMALL WIND TURBINE SYSTEMS

A toroidal wound three phase axially-magnetized, disc type, permanent magnet generator is presented in this paper. For a novel wind turbine application the generator must have a low reluctance torque and need to be direct-driven to reduce mechanical losses in the application. For this purpose the stator winding is wound around a slotless ring core. The rotor disc has 18 surface mounted magnet poles. A test of a proto type generator will be presented. 1
