Gaydenko Y. The field analysis of descriptions and modes of operation of hauling induction motors

The object of research: basic and auxiliary hauling induction motors (HID). The purpose of research: development of the scientifically methodical providing for the field and to the circuit-field analysis of descriptions and modes of operations of basic and auxiliary hauling induction motors, and also development as a result of numeral researches of practical recommendations for the improvement of the construction of HID. The methods of research: methods of mathematical design, which are based on the numeral decision of equations of the electromagnetic field of HID by the final element method; methods of theory of the nonlinear electrical engineering, methods of numeral decision of the differential and algebra systems of equations, modern algorithmization and programming methods. Theoretical and practical results and innovations: the scientifically methodical providing which consist of: field mathematical models which allow to determine and investigate descriptions and modes of operations of HID takinginto account the features of their exploitation, nonlinear properties of materials, real geometry, skin-effect in the rotor bars, and others like that is developed; methodology of determination of integral (mechanical and workings) descriptions of HID in symmetric and asymmetrical withstand modes of operation, directly from the analysis of the electromagnetic field in the active area of the motor and without application of substitution charts is developed; methodology of circuit-field design of the dynamic modes of HID is developed too. First, with the field methods, influence of precipice of rotor squirrel-cage at descriptions of HID are analyse. A subject and degree of the introduction: developed technical decisions and recommendations for investigational HID at "Smylas electromechanics factory" (Ukraine, Cherkaska region., Smyla) are inculcated. Effectiveness of introduction: improvement of constructions and improvement of the electromagnetic state and descriptions of basic and auxiliary HID. The sphere of application: universal electric locomotives which feed from the both direct and alternating current sources.
