恒流源法测量电机绕组温升的误差分析及消除

Error Analysis and Elimination for Measuring the Widing Temperature-rise of Electromotor with a Constant Flow Source Method

本文介绍一种电机绕组温升的在线测量方法。该方法采用恒流源法的基本原理 ,具有结构简单、精度较高的优点。与离线测量方法及传统的电桥法相比 ,测量效果有了明显改善。

A method for measuring the widing temperature rise of electromotor is discussed, which is based on principle of constant flow source. With this method, the structure of whole system will be simple,and the measuring precision will be higher. Comparing the method with the off line method and traditional electrical bridge method, the measurement effectness has been improved obviously.
