Procedimiento para el cálculo de los parámetros de un modelo térmico simplificado del motor asincrónico

in this paper, an asynchronous motor simplified thermal model method for conductances and capacitances estimation is presented. a low invasive technique is used. the developed procedure allows the stator temperature rise prediction, not only for dynamic regimes, but also in case of thermal stability. a parametric estimation is done through a reference model, using a genetic algorithm (ga) as optimizing method. the thermal model parameters are finally obtained with an easer experimental work, than the required by other complex experimental methods or by analytical calculations based on design data. the proposed procedure can be carry out in the particular conditions of industrial environment. its application is specially useful for asynchronous machine thermal analysis. using the data of a study case reported in literature, the method validation is done, and is applied in an industrial real case, with good precision resulted from it.
