description: The object of development is a variable frequency AC drive. Purpose of work: 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 belt of the conveyor belt was made with the subsequent selection of the power of the drive motor. Calculations of engine parameters according to equivalent circuits and the construction of natural and mechanical characteristics. A frequency converter has been selected for the rated power of an asynchronous machine. The kinematic diagram of the electric drive and the moments of inertia of the drive-conveyor system are calculated in order to calculate the braking resistor and select the braking module. The method of computer simulation of the study of transients in the modes of operation of the electric drive was used. Final qualification work is performed in the test editor of Microsoft Word 2010 on sheets of A4 format; using the Simulink graphical programming environment based on MATLAB R2017b, MathCAD 15.
