Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back The speed-torque characteristic initiation under frequency control of asynchronous electric drive Popov A.N. This article considers the principles of initiation the corrected (“excavation”) speed-torque characteristic in vary asynchronous electric drive under frequency control. In the “excavation” speed-torque characteristic as an inde-pendent variable serves the static moment at the engine rotor. Контактный телефон (4742) 43-62-82.
