Оценка сроков службы электродвигателей, работающих в повторно-кратковременных режимах

Abstract

This paper presents results of researches of intermittent mode ratings influence on thermal state and insulation lifetime of asynchronous motor. It is shown that short-term overheating in steady-state regime has an essential impact on insulation thermal aging and should be taken into account for electric motors in intermittent modes.
