摘要
从地铁现用自动扶梯采用变频器的情况，分析了当前自动扶梯采用变频技术后电动机存在的主要问题，提出了变频后电动机出现的温升问题及应对策略，认为地铁自动扶梯的变频应用应以兼顾节能与运营的关系为宗旨，从而达到既节能，又确保设备安全运行的完美组合。
The theme studies the converters presently used on the escalators in the subway, and analyses the motor＇s main problems caused by the adoption of frequency conversion technology on the escalators. It also discusses the problem of the rise in temperature in the motors after frequency conversion and gives some suggested solutions. It argues that the adoption of frequency conversion technology on the subway＇s escalators should consider the relationship between operation and energy-saving as its main idea, and achieve the perfect integration of energy-saving and safe operation of the equipments.
