摘要
对电动机的运行效率进行测试和分析是电动机节能工作的重要一环,然而在现场条件下很难直接测得电动机输出功率。通常在测得电动机的输入功率、额定有功损耗功率和空载损耗功率后,利用公式计算电动机的负载率和运行负载率[1],但这种方法只适用于质量没有发生变化的新电动机。
The test and analysis of the operation effi-ciency of asynchronous motors was one of the important measures in energy-saving of the motor. However, it was hard to test the output power of the motor in field. Usually, after the input power, rated active loss and no-load loss was measured, the load rate and operation efficiency of asyn-chronous motors could be calculated by the formula. This method was only available to the new motors.
