Abstract :
A novel coefficient modeling for skewed PM and overhang structure as a coefficient estimation method is introduced for optimal design in the 2D region for a PM motor. The novel model is constructed using 3D FEM and a response surface method (RSM) based on moving least square method (LSM). Then the novel model is coupled with an additional approximated model for optimal design in the 2D region. Finally, by combining the novel model and evolution algorithm (EA), an optimal design is performed. The usefulness of the proposed design is verified by 3D FEM simulation results.
