Problems solved by technology

[0003] The present invention aims at measuring the magnetic field of small permanent magnets in existing magnetic measuring instruments, which can only complete the measurement task for cylindrical permanent magnets, can only obtain a component of the magnetic field intensity, and cannot provide a relatively complete permanent magnet space. For the problem of magnetic field distribution map, a three-dimensional measuring device and its measuring method for the space magnetic field of small permanent magnets are proposed

Abstract

This invention relates to one small magnetic space three dimensional measurement device and its method, which can solve the problem of current magnetic measurement for small magnetic measurement only for column permanent magnetic part without one complete permanent space distribution, wherein, this invention other end of first measurement arm is fixed with one first Hall sensor and the second line supply structure and third line supply structure to form first line supply structure.

Description

technical field [0001] The invention relates to the technical field of three-dimensional measurement of the space magnetic field of a small permanent magnet. Background technique [0002] For electrical components containing permanent magnets inside, such as permanent magnet motors, electromagnetic relays, etc., the magnetic properties and magnetization effects of permanent magnets directly affect the performance of the components. The best way to understand the magnetization effect of a permanent magnet is to measure the magnetic field it generates. With the miniaturization and miniaturization of electrical components, the permanent magnet devices contained in them are getting smaller and smaller. The size of the permanent magnet devices contained in some relays is 10mm×3.5mm×0.6mm. It is not difficult to imagine that for such It is very difficult to measure the magnetic field with permanent magnet devices. The Institute of Electrical Engineering, Chinese Academy of Scien...
