1、毕业设计（论文）说明书 - 1 - 摘摘 要要 异步电动机具有结构简单、价格低廉、运行可靠等优点而成为各种生 产过程中使用最为广泛的能量转换装置，在电力、冶金、石油、化工、机 械等工农业生产中得到了广泛应用。 特别是近年来随着交流调速技术的发 展，鼠笼式异步电动机在一些高性能传动领域也占有了一席之地。它们实 现了工农业生产中一半以上的能量转换， 其运行状态直接决定了生产过程 的效益，生产线的安全以及产品的质量。在某些特殊的场合，如核反应堆 的冷却系统，煤矿的通风系统等，关键电机的运行状态直接影响着生产人 员的生命安全。因此，保证这些电机在生产过程中安全可靠运行具有重要 意义。 本设计研究鼠笼电

2、机故障诊断分析，先后介绍了鼠笼电机的结构、工 作过程、故障类型及原因，并重点研究了转子断条故障的检测。 关键字： 鼠笼电机 转子断条 故障诊断分析 毕业设计（论文）说明书 - 2 - AbstractAbstract Because of their simple structure low price and high reliability, induction motors are widely used in many aspects, such as electric power systemmetallurgypetroleumchemical engineeringmachine

3、 etc. They carry out more than half energy conversion in the work and agriculture. Sometimes the appearance of squirrel-cage induction motors effect the safety of the production line and the quality of the products. Even at some special situation, such as the cooling system in a reactor or well vent

4、ilated system of the coal mine, the movement of squirrel-cage induction motors influence the safety of the people. So it is important to make these induction motors working safely and continuity. In the paper we discuss the probable breakdowns which the induction motors always happen, and first we introduce the structure of the induction motors，then process of the working，the type of the breakdowns even the course, at last we talk about the serious stoppage of rotor bars that indu
