In this paper a comprehensive magnetic model is developed for a surface mounted permanent magnet synchronous machine (SPMSM) considering both the structural and the saturation saliencies to enable the numerical simulation of new rotor position detection algorithms. With an identifiable parameter matrix, a numerical nonlinear inductance model is proposed, in which the rotor position and the stator...
In this paper, a DC voltage pulse injection based method is proposed to detect the initial position and rotor polarity of permanent magnet synchronous motor (PMSM). The rotor angle vibration is expressed analytically as a function of the injected pulse. The nonlinear numerical simulation model of PMSM is employed, in which the saturation saliency is incorporated as well as the structural saliency...
In this paper a comprehensive nonlinear model of surface mounted permanent magnet (PM) synchronous machine (SPMSM) is developed considering both the structural and saturation saliencies. After experimentally identifying all the parameters, a nonlinear mathematic model of SPMSM is built, in which the rotor position and stator current are taken as the variables to calculate the inductances. A pulse...
