Анализ сигналов датчиков вибрации в короткозамкнутых асинхронных двигателях на основе математических моделей вибровозмущающих электромагнитных сил

Abstract

A field mathematical model for analyzing vibration-exciting electromagnetic forces in squirrel-cage induction motors is developed. Correlation between the vibration-exciting forces and vibration sensor signals is revealed. Analysis of the sensors signals under the rotor winding faults is performed to lay the foundation of a motor technical state diagnostics method.
