Abstract
The article focuses on the manufacturing process of cast copper short-circuited rotor windings of asynchronous traction motors. The basic technology developed at the Scientific Research Institute of Explosion-Proof and Mine Electrical Equipment with Pilot Production (NIIVE), Donetsk, allows the production of energy-efficient explosionproof asynchronous motors for driving mining machines and is focused on the use of only domestic materials and technological equipment. During the research, the process of preparing a copper liquid melt with a given electrical conductivity (copper melting technology) was studied, the possibility of manufacturing cast copper short-circuited rotor windings of asynchronous traction motors by vibration gravity was confirmed, the conditions for intensifying the mold filling process and solidification of the copper casting of the rotor (copper casting technology) were analyzed. The article presents the main results of technological research that can be used as initial data for the development of industrial casting technology for copper short-circuited rotor windings of AD914U1 type asynchronous traction motors.
