An analysis on induction motor reliability and lifetime estimation methods

摘要

The aim of this paper is to research induction motor's most common failures, analyze reasons and find a way to predict it. Reliability is a parameter that cannot be calculated based on induction motor parameters only. Power supply quality, detail's defects, abnormal operation mode and other cause untimely breakings that could lead to significant losses. That is why induction motor condition monitoring is an important engineering problem that demands deep research and supervision. Due to these conditions were researched methods that allows to defining induction motor parameters and evaluate its condition.
