A permanent-magnet-type reluctance generator (PMRG) has a doubly salient pole structure. The permanent magnets are embedded in the stator yoke, and the concentrated windings are arranged individually around each stator pole. On the other hand, since the rotor has neither permanent magnets nor windings, the PMRG has a simple and robust structure, low cost, and high efficiency. Thus, it is suitable for wind-turbine generation and small-scale hydroelectric power generation. Although it has large torque ripple due to the salient pole structure, we have proposed a multi-stacked PMRG to reduce the torque ripple. This paper describes the design of a three-stacked 12/8 PMRG of 400 W by the finite element method (FEM). In addition, experimental results obtained with a trial generator are presented.
