摘要
电梯中的曳引电动机实际上就是一台交流异步电动机。交流鼠笼式异步电动机变频变压调速拖动系统的电梯(VVVF交流调速电梯)由于调速时功率不变,在各种异步电动机调速系统中效率最高,同时性能也最好,是交流调速的主要发展方向。本文主要研究的是电梯中的曳引电动机在变频变压调速时的机械特性分折。
Traction motor in elevator actually was an AC non-synchronous motor. AC non-synchronous motor dragged the elevator with Variable Voltage Variable Frequency （VVVF） . Because the motor＇s power was fixed when the speed was changing, and the best efficiency and performance in all kinds of AC non-synchronous motor were otlaine. The mechanical characteristic of the traction motor in elevator was analyzed when the velocity of traction motor was varied by VVVF AC timing.
