CALCULATING THE MAIN CHARACTERISTICS OF THE TRACTION INDUCTION MOTOR FOR ELECTRIC TRANSMISSION OF URBAN ELECTRIC BUS
Journal Title: Автомобильный транспорт - Year 2018, Vol 43, Issue
Abstract
Problem. Motor vehicles built on the basis of an electric transmission have been gaining popularity recently. The most important factors here are environmental and economic ones. For large cities these two factors are closely connected and form the requirements for modern vehicles. Goal. The goal is conducting analysis of electric motors in the context of their application in a traction electric drive of vehicles with the determination of the most promis-ing one for manufacturing electric transmissions in Ukraine; calculation of the main characteristics of the traction induction motor for electric transmis-sion of urban electric bus. Methodology. The meth-ods of theoretical foundations of electrical engineering were used in calculating electric circuits of alternating current. Also the classical methods of calculating electric cars and the theory of electric drive were used in calculating the basic parameters of a traction motor for an electric transmission. Results. Based on the expert assessment, the AIR 225M2 traction motor has been selected. The calculation of the main parameters of the selected induc-tion motor for the electric transmission of the urban electric bus has been carried out. Its main electrical and mechanical parameters have been determined and its natural characteristic has been constructed. Mechanical characteristic was built when operating in an electric transmission with an induction motor AIR 225M2 in the mode of the engine and in the generator mode with the fan load torque. Originality. The complex expert estimation of traction electric motors for electric transmission has been carried out. During this assessment, not only the electrome-chanical indices of electric motors, but also economic factors were taken into account. Practical value. The results of the conducted studies allow conducting a comprehensive expert evaluation of electric motors for an electric transmission in practice. By setting the load parameters for the traction drive it is possible to determine its mechanical characteristics, both in the motor mode and in the generator mode.
