浅析桥式变频起重机系统对电动机的要求

作为搬运设备,桥式起重机为整个国民经济提高和稳步增长做出了突出贡献。因为起重机行业虽应用广泛,但工作特点比较特殊,传统多用继电器来控制,而变频调速系统的应用相对晚一些,近年来逐步引进了变频调速的起重设备新技术。本文分析变频起重机系统的电动机选型应考虑的因素并提出各机构电动型号参考。变频起重机的电动机选型好坏,直接影响起重机的工作性能,所以必须要注意电动机的选型等一系列问题。

Requirements of the Frequency Control Bridge Crane System on Motor

As the handling equipment, bridge crane has made outstanding contribution to the increasing and steadily improvement of national economy. The crane industry has been applied widely, but the work is rather special. Traditionally it is controlled by the relay, and the application of variable frequency speed regulation system is relatively late. In recent years new technologies of frequency control hoisting equipment is gradually introduced. This article analyzes the factors that should be considered in selection of variable frequency motor crane system and puts forward the mechanism of electric model for reference. The selection of frequency control crane system motor directly influences the working performance of crane, so the problems such as the selection of motor must be taken seriously.
