Nikiyan N.G. FROM MATHEMATICAL MODEL OF REAL ELECTRIC MACHINE TO ITS PERMISSIBLE LOADThe mathematical model (MM) of the real electric machine (REM) distinguished from idealized machine by deflections of constructive, technological and operation origin was worked out. Consecution of MM creation on the example of real nonsynchronous machine is presented in this article. At that the third harmonic of magnetic field in air-gap, changes of steel magnetic characteristics under influence of technological factors, symmetry violation of magnetic and electric chain of a machine are taken into account here. Determination of permissible load of nonsynchronous engine, which has defects of operation origin equal to nominal meaning at stator current, is presented here. Key words: mathematical model, deflection, real electric machine, nonsynchronous machine, permissible load
