Optimal cogging torque reduction design of dual stator radial flux permanent magnet generator

In this paper, the design of the electromagnetic structure of the dual stator type radial flux permanent magnet generator, which has an advantage over the axial flux permanent magnet generator, has been discussed from the perspective of reducing the cogging torque. To reduce the cogging torque, firstly, stator tooth pairing was designed; secondly, permanent magnet displacement was designed, and finally, stator tooth pairing and permanent magnet displacement were carried out simultaneously. The dual stator radial flux permanent magnet generator in this study was analyzed by the two-dimensional finite element method.
