The reluctance generator that did not use the rare-earth material for small wind power generation was researched. The torque characteristic and the iron loss characteristic of the generator that has the 3-dimensional gap structure were examined by the analysis and the experiment. As a result of various examinations, the effect of making to a high torque of 3-D gap structure was confirmed. On the other hand, it was clarified that the iron loss increased by using 3-D gap structure. The effects of the 3-D gap structure on the generator characteristics were clarified by this study.
