Abstract :
Finite Formulation Method (FFM) is a novel numerical method for electromagnetic field calculation based on global variables, which has been used for RF field, 3D static field, and 2D eddy current field. The result has been proved with Finite Difference Time Domain and Finite Element Method. The merit of FFM is its distinctive physical conceptions and simple calculating process. In the paper, FFM is applied on calculating skin effect of squirrel cage motor and the calculation results are compared with the results of finite element method. Based on FFM, a complex model on eddy current field for electrical machine is reported. The homogeneous and non-homogeneous Neumann Boundary condition is studied.
