Abstract :
In this paper we present a general methodology for fields analysis of axisymmetric actuators taking into account the presence of moving conductors. The methodology is based on an integral formulation and leads to an equivalent network whose parameters vary with the relative positions of the moving parts of the system. This methodology when applied to axisymmetric systems allows us to obtain accurate results in short time because of the availability of quick formulas for the evaluation of the parameters of the time-varying equivalent network. The methodology has been applied to the analysis of a tubular linear induction motor; numerical results have been compared with experimental data obtained by a prototype
