In order to address the problem of relying too much on the experience parameters and inaccuracy results brought by the traditional method of equivalent magnetic circuit, used the method which combined finite element with the magnetic circuit to make a complete design of a 300W automatic control PMSM. At first, it made the theoretical analysis and calculation for several significant parameters that had important effect on the performance of motor. On this basis, it build the preliminary motor model with the advanced motor design software MotorSolve. At the same time, relied on the solver supplied by the software, the article calculated some crucial parameters such as the cogging torque, air-gap magnetic flux, output torque efficiency, hear loss and so on.
