G-MES: a computer aided electromechanical system model generator for SPICE

Abstract

One of the problems presented when circuit simulation is used to analyze a complex electromechanical system is the amount of work required to represent each device with an adequate precision level. The calculation process required to customize each model block to represent a particular device is a time consuming task that asks for accurate knowledge of all device and model parameters and of all the trade-offs in the model set-up. The solution presented in this paper uses a general purpose simulation tool, such as SPICE, and develops a pre-processor program able to generate the SPICE input listing, using the models already available for each component or circuit block in the electromechanical system to be modeled. The program G-MES helps the designer in the selection of the best trade-off and the calculation of the selected block or component model parameters in a complete interactive way. Once the system model is completed, G-MES provides a SPICE compatible file, with the model of the complete electromechanical drive system, ready for circuit simulation.
