ENERGY-EFFICIENT ELECTRIC DRIVE BASED ON COMPOSITE MATERIALS FOR AUXILIARY UNITS OF ELECTRIC ROLLING STOCK

This article considers the issue of one of the priority areas of energy-efficient electric drives for auxiliary units of electric rolling stock based on composite materials. Currently, various DC and AC motors are used for auxiliary units of electric rolling stock. In order to efficiently use the electrical energy supplied through the power supply system and many advantages from the control side, cost reduction, productivity increase, energy efficiency, and high quality of the produced or processed material, asynchronous motors with a squirrel-cage motor are mainly used. In work to improve the energy performance of asynchronous electric motors, it is proposed to use soft magnetic composite materials in place of steel rods.
