摘　　要：提出了一种新型三维磁特性测量传感结构,利用霍尔元件测量磁场强度,B线圈测量磁通密度,减弱了由于磁极头挤压和样品振动对测量精确度而造成的影响。以软磁复合材料SOMALOYTM 700HR为待测样品分别进行了正弦激励和复杂电流波形下的磁特性实验,对比了三个正交轴向的磁特性差异,并研究了谐波次数、含量以及与基波相差对材料磁滞特性和损耗特性的影响。In this paper,a new type of magnetic property measurement sensor structure is proposed.The Hall ele-ment is used to measure the magnetic field strength,B-coil is used to measure the magnetic flux density and then the influence of the extrusion of the magnetic pole and the vibration of the sample to the measurement accuracy can be reduced.The magnetic properties of soft magnetic composite material SOMALOYTM 700HR samples are tested under sinusoidal excitation and complex current waveform loading,and the differences of magnetic properties in three axial directions are compared.The effects of harmonic frequency,harmonic content and the difference with fundamental wave on the hysteresis and loss characteristics of materials are studied.
