In 2023, a number of domestically produced microcontrollers, similar to imported ones, were engineered in Russia. These microcontrollers are used to control electromechanical systems. One of such models, MIK32 "Amur", has been used for the first time in our country by researchers from the SUSU Electromechanical, Electronic and Electrochemical Systems Regional Youth Laboratory to control a three-phase AC electric motor. A special computer program for controlling the AC motor with the MIK32 "Amur" microcontroller has been patented.
A microcontroller is an integral part of any modern technology: it generates and transmits signals to drivers that control the power switches setting an electromechanical device in motion.
"Since the beginning of the new calendar year of 2025, when organizing and equipping our laboratory, we have been focusing on the use of domestic components in electronic control systems for vehicles and other electromechanical devices," said Pavel Shaburov, research fellow at the SUSU Electromechanical, Electronic and Electrochemical Systems Regional Youth Laboratory. "With one of the newly available Russian microcontrollers, we have made our first attempts at using it in a valve electric drive. This drive could potentially be used in medium-power vehicles, lifting mechanisms with a lifting capacity of up to 1 ton, elevator- and tram-door drives, barrier lifts, fluid or gas feed shutoff valves, and other facilities using AC electric motors." The control algorithms for an AC electric motor are well-known, but what is new is that the program takes into account the design features of the domestic microcontroller model."
The program, developed by the Regional Youth Laboratory staff (P.O. Shaburov, N.Iu. Kuleva, V.D. Savchenko, and D.D. Alentsinovich) for the MIK32 "Amur" microcontroller enables control of the three phases of an AC electric motor using three signals from rotor position sensors. The program has been fully debugged and is planned for use in a valve electric drive with a large proportion of Russian components. In addition, the Laboratory team has presented the results of their prototyping and research at an international science-to-practice conference.
The Chelyabinsk scientists are currently working on fully import-substituting components for valve electric drives. In the near future, their design will incorporate Russian drivers for controlling power transistors, and the power transistors themselves.
