INCREASING THE ENERGY EFFICIENCY OF AN INDUCTION MOTOR DUE TO OPTIMIZATION OF SPECIFIC INDICATORS

Abstract

The role of the electric motor in industry is clearly high. However, speaking about complex mechanisms, the use of electromechanical converters of a specific series is impractical due to low energy efficiency. In the technical literature, electric drives used the term “registered” electric machines, i.e. machines manufactured for a specific technological mechanism, for example, the nominal motor of the main drive of the 5000 MMK mill (the installed power of one motor is 12 MW). The most common type is asynchronous due to its obvious advantages. The development of semiconductor technology makes it possible to expand the scope of regulation and control of IM, which in turn changes the vector in the production of electrical machines. The main idea is to create the most energy-efficient electric motor by changing the geometry of the stator and rotor, voltage shape, number of phases, number of poles, etc. Thus, to implement the existing idea, it is necessary to study the region of magnetic field formation by using parametric optimization and achieving the maximum root-mean-square torque.
