Abstract

When the electromagnetic field of electric motor is calculated by FEM, with the continuous motion of rotor, a large amount of computation need to be done. The difficulty of rotor motion is due to FEM mesh. The problem of distortion of mesh could besolved by EFG method, which doesn’t have FEM mesh. The coupling of EFG and FEM could eliminate the influence of mesh distortion. In order to deal with the relative motion between the stator and rotor, the paper presents a coupling method of element-free Galerkin method and finite element method(EFG-FE). The coupling method is based on overlapping domain decomposition method(DDM). The tests show that the solutions are accurate. The method is used in electromagnetic field of motor and could eliminate the errors due to distortion of elements on FE method.

Key words： Element-free method domain decomposition method EFG-FE coupling method motor motion
