Abstract

The article highlights the issues of reducing power consumption in asynchronous electric drives, increasing efficiency by using energy- efficient and energy -saving electric motors, the possibility of reducing the energy consumption of an underloaded asynchronous motor in the zone of minimum speeds through the use of a thyristor voltage converter - TVC on the control characteristics, ways to optimize energy consumption in an EA with a valve voltage regulation. The article also discusses ways to reduce power losses by ensuring the operation of the engine with optimal slip, increasing efficiency while optimizing control in the valve voltage regulation system.
