“封星”技术在电梯控制中的应用

The Application of ＂Sealing Star＂ Technology to the Elevator Control

介绍电梯控制中采用“封星”措施的优点。分析电梯在静止、低速及高速运行状况下“封星”对曳引机产生的影响．并采用磁场软件计算这几种状况下的最大短路电流，提出相应的对策。最后，通过试验验证仿真结果。

Puts forward advantages with adopting ＂sealing star＂ method in elevator control. Analysis effect to the traction machine with this method as the elevator in the static, low speed and high speed different condition. Maximum short-circuit current is calculated by using the magnetic field software for these state and corresponding measure is provided. Test the result at last.
