Wind energy has been growing fast and is recognized as the most successful energy source among all the alternative energy sources. However, due to the low utilization rate, the spread of small scale wind power generator is progressing slowly. In this paper, the stator teeth pairing design is studied to reduce the cogging torque of the dual radial flux permanent magnet generator for small scale wind turbines. The proposed method is capable to minimize the characteristic deterioration due to cogging torque reduction through an asymmetric design of teeth width. The proposed design method is verified through finite element analysis.
