05.00.00 Technical science
Description
Based on the analysis of domestic and foreign scientific and patent literature, possible options to reduce weight of electro technical steel in magnetic circuits of electrical machines are explored. A search for the best options for the manufacture of magnetic induction motors stators technology aimed at improving the utilization of electrical steel and improving the energy performance of electric machines is carried out. All the variants are described and illustrated in detail in the drawings. It is pointed out the advantages and disadvantages of each method of manufacturing magnetic wires and the reasons why certain suggestions of technology of manufacturing magnetic circuits have not been implemented in mass production. The main indicators characterizing the manufacturability of constructive decisions are recommended. Economic indicators have been put in the basis of the choice of the optimal variant while designing the electrical machine. An optimal variant should be considered the variant in which all the technical requirements at lowest total cost are met. The latter should be understood not only the cost of materials and machine manufacturers, but also the cost of operation. The dependence of the energy performance of motors with modular designs of stators from the manufacturing technology is pointed out. The existing technology of the most mass electric motors series production, the following disadvantages are typical: low coefficient of utilization of electro technical steel; high specific material capacity, the cost of technology and labor intensity of production; low labour productivity and level of automation of technological process. Due to the fact that the possibilities of increasing of the machines’ specific weight characteristics due to the usage of new magnetic and dielectric materials are exhausted, it is advisable to change the technology of electric motors production, moving away from the traditional design
