Корректировка расчета основных потерь в стали в регулируемых асинхронных двигателях

Abstract

The experimental and calculated power characteristics of a regulated asynchronous motor are compared in static and dynamic modes using the calculation technique for the main losses in steel, in which, when the specific losses are divided into two components (the hysteresis and eddy), a factor is introduced that takes into account the expansion of the hysteresis loop due to an increase in the frequency of the supply voltage. The errors in calculating the losses of active power, the efficiency of the engine in calculating the main losses in steel according to the proposed, as well as traditional methods, are determined.
