マグネット 品質 測定 システム

The DX-2012MQ rare earth permanent magnet material quality testing device uses a magnetic flux meter equipped with a one-dimensional Helmholtz coil, mainly used for measuring the magnetic flux of permanent magnet devices under the coil conditions. The magnetic moment of the device can be obtained by multiplying the coil constant. For samples with regular sizes, materials such as Br, Hcb, and BHmax can be calculated. Through experimental verification, the use of one-dimensional coils to test axially magnetized cylindrical, circular, and square rare earth permanent magnet samples can accurately test the total magnetic moment M (Mz, to be precise) of the material. By using the material BH demagnetization curve to approach a straight line, the three important parameters Br, Hcb, and BHmax of the material's magnetic properties can be accurately calculated to determine the quality of the material, It is well used in the transmission of rare earth permanent magnet material quality between material enterprises and material usage enterprises. The accuracy and repeatability of magnetic moment testing are far superior to using BH testing instruments to test standard sample transmission data. The testing efficiency is high, which can achieve full inspection of all magnetized samples and timely detection of device defects, while ensuring the judgment of material magnetic energy product level.

The DX-2012MQ レア 地球 永久 磁石 材料 品質 テスト デバイス 使用 a 磁気 磁束 メーター and ヘルムホルツ コイル to テスト the 品質 of レア 地球 材料, which has become a popular inspection method among enterprises. Although the magnetic properties of the testing material are not accurately measured by the permanent magnet material BH measurement device, and the intrinsic coercivity Hcj parameter of the material cannot be 提供. しかし、, due to its more reliable testing magnetic moment data and lower equipment costs, Appropriateable for all material manufacturing and communication between users, it will play a greater role in the field of magnetic measurement in the future.

全体, the DX-2012MQ レア アース パーマネント マグネット 材料 品質 テスト デバイス is a 信頼性 and 費用対効果 ソリューション for industry professionals who need to test the performance and quality of rare earth permanent magnet materials.
