Abstract

The vibration in Three-Phase Induction Motors (TIM) is due to mechanical and electrical forces existing during the motor operation. Vibration problems in induction motors can be extremely frustrating and may lead to greatly reduced reliability increasing the maintenance cost. The vibration was measured using fiber Bragg gratings (FBG) installed inside the motor between two stator teeth. The vibration frequencies in TIM are predicted using a model of the forces present in the air gap considering a static and dynamic rotor eccentricity. Two FBGs were positioned between two stator teeth, separated by 120° from each other. The analysis of the vibration spectrum at 60 Hz motor power supply presents the frequencies 60 Hz, 120 Hz, 180 Hz and 240 Hz. This combination of the mechanical and electrical frequencies continue to appear even when the motor electrical supply frequency is reduced by half. The measurement present in this paper can be used to determine some TIM parameters, like the effect of the motor power supply on its vibration signal and also be used like a potential maintenance tool for predictive purposes with high efficiency to continuously monitor the TIM.

用光纤光栅传感器测量感应电机在动态偏心下的振动

三相感应电动机(TIM)的振动是由于电动机运行过程中存在的机械力和电磁力引起的。振动问题在感应电机可以是非常令人沮丧的，并可能导致大大降低可靠性，增加维护成本。利用安装在电机内部两个定子齿之间的光纤布拉格光栅(FBG)测量振动。考虑转子的静态和动态偏心，利用气隙中存在的力模型预测了TIM的振动频率。两个fbg被放置在两个定子齿之间，彼此相隔120°。分析了60hz电机电源的振动频谱，给出了60hz、120hz、180hz和240hz的频率。即使电机供电频率降低一半，机械和电气频率的这种组合也会继续出现。本文提出的测量方法可以用来确定一些TIM参数，如电机电源对其振动信号的影响，也可以作为一种潜在的维护工具，用于预测目的，高效地连续监测TIM。
