The traditional way for motor performance analysis is magnetic circuit method. Complex magnetic circuit calculation is the problem of this method which makes the design of motor with complex or shaped structure inefficient. To solve this problem, a joint Maxwell 2D and Maxwell circuit editor simulation framework based on test generator scenario was proposed. A comparison study between the proposed simulation method and an experiment with an outer-rotor permanent-magnet synchronous motor was presented. And the results showed that the simulation data fit the result of the experiment pretty well. Another comparison study between the proposed simulation method and the magnetic circuit method showed that the error of the calculation data of the two methods was less than 1%. The work in this paper can be used to decrease the design interval for some less restricted motor application.
