The method was used to carry out mathematical modeling for the follow-up of transitional processes during the start-up of an asynchronous engine to drive a rotary-pulsation apparatus for the preparation of water-grain feed for the clarity and frequency of the frequency changer.
Mathematical modeling of transient processes during the start-up of an asynchronous electric motor for driving a rotary-pulsation apparatus for the preparation of liquid grain feed in the absence and presence of a frequency converter was carried out using the Matlab Simulink application program package. The following start-up parameters of the asynchronous motor were obtained: the current in the stator windings, the speed of rotation of the rotor and the electromagnetic moment on the motor shaft. The dynamic mechanical characteristics of the asynchronous motor during its start-up are obtained. A comparative analysis of simulation results with and without the use of a frequency converter was carried out. It is shown that the use of a frequency converter significantly improves the starting characteristics of an asynchronous motor.
Key words: rotor-pulsation apparatus, asynchronous motor, frequency converter, transient processes during start-up
