Modelling of a Permanent Magnet Synchronous Motor and its Control Circuit in Simulink Environment

The most commonly used electric motor in electric vehicles is the permanent magnet synchronous motor. The primary production and refinement of rare earth materials used in these motors are immensely damaging to the environment. A new wave of technology in the aspect of electric motors is emerging and that is the non-rare earth element magnet assisted synchronous reluctance motor. During the development process it is beneficial to keep the expenditures at the minimum. To reach that goal a comprehensive simulation of the designed motor and its control circuit could be the answer. It is reasonable to use software based on finite element calculations such as FEMM and mathematical simulations as Matlab Simulink. By implementing the equations and methods described in this paper the electric powertrain can be created generally. The specification is highly dependent on the input parameters that are extracted from finite element 2D calculations. In this case, the model approximates the expected behaviour of the investigated construction. A complete driving cycle can be examined, operating points can be determined, and the efficiency map can be created to help the research.
