Kravets O. The testing of the electromagnetic parameters of induction motors by equilibration in frequency-control drive systems

The object of research is to manage asynchronous electric drive with an unstable electromagnetic parameters of induction motors; purpose is to improve the regulatory properties of frequency-controlled drives by increasing the probability control electromagnetic parameters of induction motors; theoretical results - first proposed compensation-bridge method for control of induction motors electromagnetic parameters with multiple circuits under nonsinusoidality voltage or current supply, which provides information in real time and improve the regulatory properties of induction motors, improved methods of induction motors control parameters using as informative parameters of balancing domestic small quantities - derivative linkage and linkage that enables determination of induction motors parameters for nonlinearity magnetizing inductance, took the further development of a method of control parameters of nonlinear models by the introduction of new spectral parameters and the use of instantaneous values of currents, which enables experimental evaluation of induction motors electromagnetic parameters in both unsaturated state and in saturation mode magnetic circuits. The degree of implementation is obtained research results introduced in LLC "Promavtomatika Vinnitsa". The results are also used in Vinnytsia national technical university for training in the specialty 7.090603 "Electrical power system." Field use is control systems of electric drives.
