Electric drive (ED) on the basis of frequency converter (FC) with multilevel IGBT voltage inverter and asynchronous squirrel-cage rotor or synchronous electric motor (EM), with nominal input power line voltage FC 6-10kV is designed to drive production mechanisms.
The frequency converter provides regulation of speed of the electric motor, acceleration of the electric motor up to the nominal speed and its transfer to operation from the mains, as well as "pick-up" of the electric motor connected to the mains with subsequent frequency regulation of its speed.
The EA is designed for operation in temperate and cold climate conditions in a closed heated room or in a block-modular building (BMZ) of outdoor installation with a microclimate maintenance system.
