微拖动装置自1965年问世以来,使用者日多,现已广泛用于多绳摩擦式和单绳缠绕式矿井提升机。随着工业水平的提高,自动化提升逐渐增多,要求使用微拖动的用户不断增加,迫切需要了解该设备的有关情况。这里,我们对矿井提升机用微拖动装置作一简单介绍。一、概述我国矿山大、中型提升机广泛地采用交流绕线型电动机拖动。众所周知,绕线型电动 Since its introduction in 1965, micro-actuators have been used by more and more users and are now widely used in multi-rope friction and single rope winding mine hoists. With the improvement of the industrial level, the increase of automation is increasing. The number of users who use micro-dragging is increasing constantly. It is urgently needed to know the situation of this equipment. Here, we make a brief introduction of mine hoist micro-actuator. First, an overview of China’s mine large and medium-sized hoist widely used AC winding motor drag. As we all know, wound electric
