STRAY-LOSSES MEASURING OF ASYNCHRONOUS MACHINES BY DOUBLY-FED METHOD

本文阐述了中小型异步电动机附加损耗测试存在的问题，提出了双频法测定异步电动机附加损耗的试验方法，通过对不同容量三相绕线式异步电动机反复试验，找出附加损耗的规律性，导出了附加损耗与电机容量关系系数，按此方法，可以方便的得出绕线式异步电动机附加损耗，经校准比较准确．

his paper investigates current problems in measuring stray losses in middlesmall asynchronous machines, provides the method for measuring such machines.Through a great deal of tests, their regularity is found and relationship factors between stray losses and motor capacities are given.It is convenient to use such methods to obtain the stray losses and they are verified to be exact.
