摘　　要：电压的波动对电动机铁损耗影响较大。国标GB/T 1032—2005中给出电动机铁损耗与电压平方比成正比的关系,实验结果表明其误差较大。本文对此做了大量的实验,在额定电压附近利用实测数据对铁损耗与电压的关系进行曲线拟合,得到了一种误差较小的测试铁损耗的方法。Voltage fluctuations impact on motor iron loss is larger. The relationship given in GB/T 1032-2005 is that iron loss is proportional to the square voltage ratio. But the experimental results show that the error is bigger. This paper does a lot of experiments on that. In the vicinity of the rated voltage, use the measured data to do the iron loss and voltage curve fitting, and then getting a kind of method to test the iron loss of smaller error.
