| Summary: | The recent developments in the area of electric vehicles resulted in the growth of the interest for Axial Flux Permanent Magnet Motors, mainly because of their high power density. For the design of the motor drive it is of extreme importance to have the motor parameters, although many times the manufacturers do not provide them. To overcome this problem, in this paper is presented a methodology to obtain the parameters of this type of motor, in order to make possible the implementation of the d-q model. In synchronous motors with permanent magnets the inductance changes with the rotor position, so the d-q model is used to simplify the analysis and to get a better understanding of the motor parameters. Thus, this paper presents the d-q model of an axial flux permanent magnet synchronous motor with two external stators and one internal rotor.
