摘　　要：本文以民用建筑中常用的鼠笼式异步电动机为例,分析笼型异步电机的基本结构和工作原理,对异步电动机常用启动形式进行介绍,对不同电机启动方式进线比较,从技术经济角度着重分析了星三角启动与软启动。并通过计算启动压降及单台最大起动容量给出变压器、柴油发电机允许启动最大电机功率限值。结合民用建筑特点给出各种启动方式电动机功率。Taking the squirrel-cage asynchronous motor which is commonly used in civil architecture as an example,this paper analyzes the basic structure and working principle of the squirrel-cage asynchronous motor,introduces the common start-up mode of different kinds of asynchronous motors,and focuses on analysis of the star-delta starting and soft starting from the perspective of technology and economy.The maximum motor power limit of transformer and diesel generator is obtained by calculating the starting voltage drop and the maximum starting capacity of a single set.The motor power of various starting modes is obtained by combining the characteristics of civil architecture.
