立式异步电机温升计算分析

Calculation and analysis of temperature rise on vertical asynchronous motor

电机性能评价的一个关键指标是定子绕组温升。当电机温升超过标准值时,需从电机结构、冷却器设计、试验方法等多方面去加以分析。本文以解决一台立式异步鼠笼电机温升超标为例,对异步电机的温升计算进行了详细的分析。

A key indicator of performance evaluation of motor is the temperature rise of stator winding.When the motor temperature rise exceeds more than standard value,it is required to analyze from the motor structure,cooler design,test method and other aspects.In this paper,the calculation of the temperature rise of a vertical asynchronous squirrel-cage motor is analyzed in detail.
