摘　　要：为了提升电梯的使用安全,针对老旧永磁同步驱动电梯未设置电气制动功能存在的风险,并结合新版TSG T7007—2022《电梯型式试验规则》中要求设置其他制动装置(如电气制动)开展分析,本文主要分析如何通过封星技术来实现电气制动功能,分别从封星技术的发展、实现原理、如何检验及使用条件等角度分析,并在此基础上探讨“电机封星”技术在高速电梯上的应用问题,对预防电梯在制动力突然衰减或消失带来的“冲顶”或“蹲底”的危险有重要意义。In order to improve the safety of elevator use,this paper focuses on the risks of old elevators driven by permanent magnet synchronous motors for without electrical braking function,and carries out analysis based on the requirements of setting up other braking devices such as electrical braking in the new version of TSG T7007-2022,Regulation for type test of lifts.The paper mainly analyzes how to achieve electrical braking function through star sealing technology,from perspectives of the development,implementation principle,inspection and usage conditions of star sealing technology.It explores the application of“motor star sealing”technology in high-speed elevators,which is of great significance for preventing the danger of“top collision”or“falling”caused by sudden attenuation or disappearance of braking force in elevators.
