摘　　要：直线异步电机的可靠性对用户和制造商均极为重要。分析了直线异步电机的故障树,提出了电机的失效判据和主要的可靠性指标。现场使用的电机基本运行在偶然失效阶段,因而其失效率近似为一常数。在恒定失效率的假设下,推荐采用定时或定数截尾试验方案在现场进行电机的可靠性试验。The reliability of linear induction motors(LIM) is very important for both manufacturers and clients. In this paper, the fault tree of LIM was analyzed; its failure criterion and reliability indices were discussed. The motor on the spot is in operation in the random failure period and therefore its failure rate is approximately a constant. On the basis of the afore-said constant failure rate, a reliability test, using constant time or constant number tail cutting scheme, is recommended.
