Evaluation of additional losses of an asynchronous motor for electrical equipment of the mining industry

Asynchronous motors of the ADKV series are widely used in electric drives of scraper conveyors located in coal mines of the mining industry, and are the most common converters of electrical energy into mechanical energy. They consume about 40% of all electricity. The quality, reliability and level of technical development of asynchronous motors have a significant impact on the level of implementation of production processes in the mining industry. Thus, the improvement and elaboration of aspects related to energy performance and energy efficiency of electric machines is an urgent task. The article is devoted to the assessment of the level of additional losses in the steel of the magnetic circuit of an asynchronous motor with a shortcircuited rotor, which is an element of the electromechanical system of electrical equipment of a mining enterprise. The surface and pulsation losses caused by the toothed structure of the surfaces limiting the air gap of the electric machine are considered. The results of the work are based on the laws of electromechanical energy conversion and on the equation of the energy balance of active power. The object of research is asynchronous motors with a short-circuited rotor with a voltage of up to 1000 V for the needs of the mining industry. The influence of additional losses in steel on the energy efficiency of engines has been studied. The analysis of surface and pulsation losses depending on the number of teeth of the stator and rotor is carried out. An algorithm for selecting the number of teeth to achieve the highest energy efficiency is shown. The obtained simulation results provide the maximum efficiency of operation of asynchronous motors in electric drives of scraper conveyors of the mining industry, thereby increasing the overall energy efficiency of the drives of mining equipment.
