电梯轿厢滞留工况下曳引机转矩的分析

Analysis of Traction Machine Moment in the Case of Elevator Car Stalling

就电梯在满足其他工况转矩条件下。是否就能满足滞留工况下的转矩提出疑问。通过对滞留工况下曳引机的转矩的计算。尤其是在满足曳引条件下对曳引机转矩的计算，证明滞留工况下曳引机转矩很大，远超过125％负载下转矩，由此说明关注滞留工况下曳引机转矩的重要性。

This paper raises the question that whether elevator can meet with the traction moment in car stalling condition or not while it meet with the moment in the other working condition. Through derivation and calculation, especially the calculation of the moment in the case of meeting with traction conditions, it is proved that the traction machine moment in car stalling condition is large which is more than the moment of 125% load. That clarifies the importance of attention to traction machine moment in car stalling condition.
