Разработка электропривода сортировочного конвейера мощностью 2*7,5 кВт

Abstract

разработать электропривод, обеспечивающий постоянную скорость двигателя в пределах 3000 об⁄мин , обеспечить плавность пуска электропривода. В выпускной квалификационной работе был сделан расчет ленты ленточного конвейера с последующим выбором мощности приводного двигателя. Расчеты параметров двигателя по схемам замещения и построение естественной и механической характеристик. Осуществлен выбор преобразователя частоты по номинальной мощности асинхронной машины. Рассчитаны кинематическая схема электропривода и моменты инерции системы привод-конвейер с целью расчета тормозного резистора и выбора тормозного модуля. Применялся метод компьютерного моделирования исследования переходных процессов в режимах работы электропривода. Произведено программирование конвейера в программе TIA Portal V14. Выпускная квалификационная работа выполняется в тестовом редакторе Microsoft Word 2013 на листах формата А4; с использованием среды графического программирования Simulink на основе MATLAB R2022b, MathCAD 15.

to develop an electric drive that provides a constant engine speed within 3000 rpm, to ensure smooth start-up of the electric drive. In the final qualifying work, the calculation of the conveyor belt was made, followed by the choice of the power of the drive motor. Calculations of engine parameters according to substitution schemes and construction of natural and mechanical characteristics. The frequency converter was selected according to the nominal power of the asynchronous machine. The kinematic scheme of the electric drive and the moments of inertia of the drive-conveyor system are calculated in order to calculate the brake resistor and select the brake module. The method of computer simulation of the study of transients in the operating modes of the electric drive was used. The pipeline was programmed in the TIA Portal V14 program. The final qualifying work is performed in the Microsoft Word 2013 text editor on A4 sheets; using the Simulink graphical programming environment based on MATLAB R2022b, MathCAD 15.
