摘要： A system for controlling the braking force applied to an elevator car driven by an A.C. motor in which means for controlling the cut-off position of the elevator car driving motor from the power supply depending on the load of the elevator car are provided so as to ensure accurate arrival of the elevator car at a desired target floor and a comfortable sense of ride under every condition of the load. The elevator control system is advantageous over prior art systems of this kind in that the capacity of the motor can be reduced and a better sense of ride can be obtained.
摘要翻译：一种用于控制施加到由AC电动机驱动的电梯轿厢的制动力的系统，其中设置有用于根据电梯轿厢的负载从电源控制电梯轿厢驱动电动机的截止位置的装置，以便确保电梯轿厢在所需目标楼层的准确到达以及在负载的每个条件下的舒适感觉。电梯控制系统比现有技术的这种系统更有优势，因为可以减小电动机的容量并且可以获得更好的乘坐感。
