摘要：
Based on a closed-circuit testing equipment, eddy current loss measurement method of the permanent magnetic material is proposed and studied in this paper. The tested material sample is NdFeB, which has been widely used in electrical machines. The NdFeB is usually coated with corrosion-resistant metal, such as highly conductive zinc and copper to resist corrosion in practical use. The coating material may influence the eddy current loss of the permanent magnet. In this situation, eddy current losses of the NdFeB sample with and without coating are measured and compared with sinusoidal excitation at different frequencies. The experimental results provide very important reference in electrical machine design.
