电机中的铁损知识是成功设计高效电机所必需的。本文介绍了一种测量电机铁损和局部损耗密度的热像技术。首先，在COMSOL多物理场中对所述问题进行了三维数值求解，以研究测量技术的可能性。在24/12 V单相Transformer上演示了实验测量过程。通过以300 Hz的恒定频率改变施加的电压来向Transformer提供激励。利用红外摄像机对三种不同的磁通密度下的堆芯在通电瞬间的图像进行了拍摄。根据初始温升率估算铁损，并与直接从瓦特计获得的铁损进行比较。结果表明，所开发的系统可以准确地估计铁损密度和分布在很大的范围内，误差小于6%。但测量条件对测量结果的准确性有一定的影响。
The knowledge of core losses in electrical machine is required for the successful design of highly efficient machines. This paper presents a thermographic technique for measuring core loss and localize loss density in an electrical machine. First, a 3D numerical solution of the stated problem was carried out in COMSOL multi-physics to study the possibility of the measurement technique. The experimental measurement process was demonstrated on a 24/12 V single-phase transformer. The excitation was supplied to the transformer by varying the applied voltage at a constant frequency of 300 Hz. IR camera was used to obtain the images of the core at the instant of supply for three different flux densities. The core losses were estimated from the initial rate of temperature rise and compared with the core loss obtained directly from the wattmeter. The results show that the developed system can accurately estimate core loss density and distribution over a wide range, with an error margin of less than 6%. However, the accuracy of the results obtained is affected by measurement condition.
