摘要
针对拖动电机的广泛使用,分析其起动特性,阐述其降压起动中起动时间、起动负荷计算整定的必要性及重要性,研究得出一种可广泛使用的计算大功率拖动电机起动电压、起动负荷转矩及起动时间的方法,并介绍此方法的应用效果。
Aiming at the extensive usage of the drag motors,the start characteristic is analyzed.The importance and necessity of start-up time and start-up load are mainly presented in the drag motors＇ prostrate start-up process.And a computational method of start-up voltage,start-up load and start-up time is worked over for high-power drag motors,and the applications and the results are given.
