Abstract: Nowadays, with the development of science and technology, electric motors have found wide application in various fields, including in the mining industry due to their high efficiency and stability compared to internal combustion engines (diesel and gas engines). In particular, the use of electric motors does not cause emissions and environmental pollution, thus improving working conditions both in open and in underground mining facilities. However, battery-powered equipment also has certain disad-vantages that require continuous research and development to optimize the operation of the electric propulsion system. An analysis of the advantages and disadvantages of existing electric propulsion systems shows that an electric propulsion system with two asynchronous motors, as well as vector modulation systems of autonomous inverters and vector motor control systems, provides the highest efficiency of electrical equipment.
