It is impossible to imagine any modern mechanism in any field of technology that has not been driven by an automated electric drive. In the electric drive, the main element that converts electrical energy into mechanical energy is an electric motor, which is controlled by converters and control devices in order to form static and dynamic characteristics of the electric drive that meet the requirements of the production mechanism.
Equipment for the production and use of compressed air is universal and safe, it is widely used in modern industry. Compressed air is used as a source of energy, a medium for cleaning (purging), a means of transportation and even as a source of cold.
Air compressors make up more than 80% of the total compressor fleet. Compressed air production and distribution systems in industry consume up to 10% of electricity. Unfortunately, there is an opinion that compressed air is cheap, although only 5-10% of the consumed electricity is spent on useful mechanical work. The cost of producing compressed air is 5-15% of the cost of production, and for some industries reach 30% or more. Reciprocating, centrifugal, and in recent years screw compressors have been widely used as air compression machines.
 In agricultural production, compressors are used to supply air and gases of the main or by-products of the technological cycle. These machines are common in gas supply systems. Compressors are also widely used in gas turbines.
The laboratory stand for research of the piston compressor is modernized. On the basis of technical and economic indicators the electric drive system is selected, the electric motor is calculated and selected, it is checked with heating, overload capacity and start-up conditions, characteristics in statistical and dynamic modes are investigated, and also electric schemes of SAEP of the main lifting mechanism are developed. To verify the correctness of the adopted design methods, modeling was performed in Matlab.
