Abstract. A large share of electricity consumption in agricultural production falls on electric drives, in particular, in grain drying equipment. The electric drives of the fans of grain drying units are equipped with asynchronous motors and in the overwhelming majority they are non-automatic. They are not able to provide modern requirements for reliability and quality of management, their energy efficiency is relatively low. Automation and development of automated control systems of electric drives of fans allows to solve this problem. As such systems, a frequency control system with a scalar control principle and a parabolic relationship between the voltage and the frequency of the feeding network can be used. Scalar frequency control systems are widely used for fan drives and pumps, and vector frequency control is used for electric drives with a wide range of regulation. These systems are energy-efficient, and energy saving in their use is up to 30%. One of the tendencies in the field of energy saving technologies of recent years is the use of frequency-controlled drives based on asynchronous short-circuited electric motors and semiconductor frequency converters, which reduce the consumption of electric energy, increase the degree of automation, convenience of operation of equipment and quality of technological processes. As part of a frequency-regulated asynchronous electric drive, the choice and matching of the parameters of the frequency converter and the asynchronous short-circuited engine is the main issue. Since, when changing the frequency of the electric drive, its energy parameters change, then it is necessary to determine the rational parameters of the performance of the asynchronous motor. To do this, an ANSYS MAXWELL RMXPRT software simulates an asynchronous 15 kW motor with a nominal frequency of 1460 rpm. Its main operating characteristics have been constructed and analyzed, namely, depending on the moment of the engine, the phase current and the efficiency of the rotor speed, as well as the dependence of the engine moment on the slip. A parametric analysis was performed for the moment and engine efficiency at variations of the frequency from 50 to 400 Hz.
