Abstract: Facing the particular needs of each pole‘s magnet on the calculating in finite element for doubly salient electro-magnetic motor for electric vehicle.Used the improved triangulation automatically generating algorithm,control the density and angle-changing of the triangle in various regions freely at the base of Delaunay’s algorithm.The results show that it is a capable of adaptively generating meshes with reasonable quality.It has been applied to the calculating in finite element of the external rotor doubly salient electromagnetic motor in vehicle.
