FE-2100MQ Rare Earth Permanent Magnet Material Quality Test Device

FE-2100MQ rare earth permanent magnet material quality testing device uses fluxmeter and Helmholtz coil testing the quality of rare earth materials has become the most popular among enterprises Inspection method, although the magnetic performance of the test material is not as accurate as the permanent magnetic material BH measuring device, and the intrinsic coercivity Hcj parameter of the material cannot be provided, but the test magnetic moment data is more reliable, the equipment cost is lower, and it is suitable for all materials manufacturing Communication and communication with users will play a greater role in the field of magnetic measurement in the future.

 

FE-2100MQ rare earth permanent magnet material quality test device uses fluxmeter With configuration one-dimensional Helmhol This coil, it is mainly applied to the permanent magnet device under the condition of the coil For magnetic flux measurement, multiply the coil constant to obtain the magnetic moment of the device. For samples of regular size, the materials Br, Hcb, and BHmax can be calculated. Experiments have verified that the use of one-dimensional coils to test axially magnetized cylindrical, toroidal, and square-type rare earth permanent magnet samples can accurately test the total magnetic moment M (to be precise, Mz) of the material, and the material BH demagnetization curve is close to The straight line can accurately calculate the three important parameters of the magnetic properties of the material, Br, Hcb, and BHmax, so as to judge the quality of the material. It is well used for the transfer of the quality of rare earth permanent magnet materials between material companies and material users. Among them, the accuracy and repeatability of the magnetic moment test are far superior to the use of BH test equipment to test standard samples to transmit data. The high test efficiency can achieve full inspection of all magnetized samples, and timely discover device defects, while ensuring that the materials Judgement of magnetic energy product level.
