Quality testing device DX-2012MQ

automaticcomputer-controlledfor rare-earth permanent magnet materials

The DX-2012MQ rare earth permanent magnet material quality test device uses a fluxmeter to configure a one-dimensional Helmholtz coil, which is mainly used to measure the magnetic flux of the permanent magnet device under the condition of the coil, multiplying the coil constantly to obtain the magnetic moment of the device. For the size of the sample, the materials Br, Hcb, and BHmax can be derived. DX-2012MQ rare earth permanent magnet material quality test device has been verified by experiments that the one-dimensional coil test axially magnetized cylindrical, circular and square rare earth permanent magnet samples can accurately test the total magnetic moment M of the material (accurately Mz), using the material BH demagnetization curve close to The straight line can accurately calculate the three important parameters Br, Hcb and BHmax of the magnetic properties of the material, so as to judge the quality of the material, which is very good for the quality transfer of rare earth permanent magnet materials between materials companies and materials users. In the middle, the accuracy and repeatability of the magnetic moment test are far superior to the standard sample transfer data measured by the BH test instrument. The high test efficiency can realize the full inspection of all the magnetized samples, and the defects of the device can be found in time, and the material can be guaranteed. The judgment of the level of magnetic energy product. ● Adopting a single-chip design, the program is automatically calculated, which is intuitive and convenient; ● Suitable for all rare earth permanent magnet materials, low equipment cost;
