| Abstract |
Dual stator type generators have excellent output per unit volume and can generate high efficiency in a wide operating range based on high voltage at low wind speed. The dual stator type generator can minimize the cogging torque generated by the two inner and outer generators through the mutual displacement of the stator or the permanent magnet. However, this method has a disadvantage of lowering the output and efficiency of the generator. Therefore, this paper presents a design method applying stator teeth pairing to reduce cogging torque of dual stator type generators. The proposed method is to design the width of inner stator teeth and the width of outer stator teeth to be different from each other. To verify the validity of this paper, we present the results of 2D finite element analysis and verify the validity of this paper. |
