摘要
本文提出了一种测量小间隙磁场强度的新方法。根据磁场的环路定理,建立了小间隙的磁场强度测量的外推方法的基本公式和测试方法。进一步,使用所建立的方法实测了相对大间隙情况下小型发电机转子与定子之间的磁场强度,使用所推导出的公式外推出小间隙的磁场强度。结果表明,本文所提出的小间隙磁场强度测量的外推方法和公式简便可行;在这种测量方法中霍尔片的厚度对实验精度有影响。这种磁场强度的测量方法特别是小间隙磁场强度测量领域有着重要的实际意义。
A new expanding approach for measuring magnetic field strength in small gap is proposed in this paper, which is based on the loop theorem in magnetic field theory. Further more, measurement of the magnetic field intensity between the rotor and the stator is conducted and the expanding the launch of small space of the magnetic field strength is performed. It indicates that the new approach is simple and viable, the thickness of the Hall effect piece influences the viability of the measurement significantly. The new approach is important for measuring magnetic field intensity especially for magnetic field intensity in small gap.
