摘要: Induction motors, key elements for industry, are susceptible to one or more faults at the same time; yet, they can keep working without affecting process, but increasing production costs. For this reason, a monitoring system that efficiently diagnose induction motor condition, even under multiple combined faults, is demanding task. In work, methodology and its implementation into field programmable gate array an online real-time of presented. First, fractal dimension approach, using Katz algorithm, introduced as measure variation 3-axis startup vibration signals considering these describe changes on dynamic characteristics due different faults. Then, artificial neural network determines in automatic way condition according values. The obtained results show higher overall efficiency than previous ...
