Hardware-software complex for experimental research of electric drives of asynchronous motors with squirrel-cage rotor with traditional winding and motors with combined winding

Abstract

THE PURPOSE. Modern requirements for electric drives impose increasingly stringent conditions for energy efficiency, dimensions and weight. The weight and size parameters are especially noticeable in relation to the rapidly developing electric transport. The achieved technological limits practically do not give tangible results in improving the characteristics of known structures, so there is a struggle for units of percent and fractions of a percent in terms of increasing the efficiency of equipment.MATERIALS. Debugging and fine-tuning of electric drive elements requires numerous tests on research benches using measuring channels and analog-to-digital conversion (ADC), digital-to-analog conversion (DAC), digital-to-digital conversion (DDC).RESULTS. The creation of research stands implies the development of a hardware-software complex (HSC) based on high-speed computing devices. The structure of the HSC included the developed frequency converter with the possibility of adjusting the algorithms for controlling the electric motor and the mathematical model of the electric motor itself. The object of experimental research was prototypes of electric drives based on asynchronous electric motors with a squirrel-cage rotor and a combined stator winding.CONCLUSION. The article discusses ways to organize the measuring and control channels of the measuring and information system of the research stand, which makes it possible to study samples of asynchronous electric motors in idling and under load modes.
