摘要：
Paper is devoted to research the dynamics of thermodynamic models for Totally Enclosed Fan-Cooled (TEFC) induction motors on the basis of the thermal lumped circuits. Clusterization a series of TEFC motors motors for general industrial application was performed. It allowed to group motors into clusters with consimilar parameter vectors of 5-node thermodynamic model. With using a method of genetic algorithms was carried out determination of the parameters of generalized 5-node thermal models corresponding to different clusters. An approach is proposed which allowing carry out a general analysis of the dynamic properties TEFC motors. With the use of frequency response for thermal models was revealed the actual area for gain values over a channel from the motor torque to the stator winding temperature for typical TEFC motors with mesh windings. The possibility of using the obtained thermal models to evaluate the influence of temperature fluctuations on the insulation resource expenditure acceleration was shown.
