Влияние насыщения стали магнитопровода и вытеснения тока в обмотке ротора на динамические характеристики регулируемых асинхронных двигателей

Abstract

Results of research on adjustable-speed induction motors in dynamic conditions have revealed that, in case of taking into account influence of magnetic core’s saturation and rotor current’s displacement, the error of stator’s current jump determination decreases to 6 % in comparison with 13 % without allowing for control law of U / f = const, and, accordingly, the error decreases to 3 % in comparison with 17 % for frequency control law of Ψ2 = const.
