“…Moreover, the use of Neodymium-Iron-Boron permanent magnets enables a volume and mass reduction [3]. The compact arrangement and the natural action of the rotor disks generate a good refrigeration of the stator windings, since they are exposed to air [6]. Another advantage is that the machine without slots generates small variations of magnetic flux thus reducing the eddy current losses in the rotor discs and magnets [7].…”

Abstract. Nowadays, there is a global trend for searching new sources of energy with lower possible aggression to the environment and to humans in generation of electric power. According to the Brazilian Electricity Regulatory Agency (ANEEL), the generation through wind power now is around 1200MW of installed power, and the government has already signed 140 new projects to be installed until the end of 2013, with which the country would produce about 5000MW. This favorable scenario for the development of wind power, leads to several jobs in the area of forecasting and designs of electrical machines for wind turbines. This paper deals with the study of a 50 kW Torus generator with rare-earth permanent magnets applied in wind turbines. Such topology is compact, simple and has a high efficiency.
