This paper presents a novel sequential strategy which is based on finite element method (FEM) and optimization methodology. It is proposed to deal with the multivariable designing of the permanent magnet (PM) motor. In this paper, the property variables are divided into groups by a key factor, each group only involves one or two variables. Then the optimization process will be obtained sequentially by the groups. After obtains the optimal result for one group of property variables, next group of variables will be employed in the optimization. This process will continue until the designing maximizes its power efficiency. This method distributes the multivariable optimization into single variable and bi-variables optimizations. It can reduce the computing complexity and save a lot of working time. In order to check the efficiency of this method, this project compares this new strategy with a normal optimal FEM method.
