The FE-2100SD soft magnetic material DC measurement system is a comprehensive soft magnetic measurement equipment that can automatically measure the basic magnetization curve and basic hysteresis loop of soft magnetic materials under DC conditions. It conforms to GB/T13012-2008 and other soft magnetic materials. The DC measurement standard can accurately measure the static magnetic characteristic parameters such as initial permeability μi, maximum permeability μm, saturation magnetic induction Bs, remanence Br, coercive force Hc and hysteresis loss Pu.
In the measurement of the DC characteristics of soft magnetic materials in the magnetization curve, the most difficult to test the accurate amount is the initial permeability. The test error can reach tens of percent with the impact galvanometer or the scanning method. Most domestic products use simulation The impact method effectively avoids the influence of fluxmeter drift. The FE-2100SD soft magnetic material DC measurement system inherits the technology of the simulated impact method, improves the impact waveform and signal, and at the same time continuously improves the integrator drift control technology, and optimizes the control of the test point, and through the excellent performance of dB/ The dt control technology, high-resolution current control technology, and magnetic flux sampling technology make the entire test extremely well controlled. It has obvious advantages over domestic and foreign counterparts in the testing of micro-components, low-Br materials and iron powder core materials.
In 2016, according to the vision of Mr. Qu Qingchang, one of the founders of the DC magnetic performance measurement device for soft magnetic materials in China, and a more in-depth study on the hysteresis loop measurement method of soft magnetic materials. Up to half a year of experimental comparison and update of the test equipment method found the defects of the current magnetic measurement equipment, and completed the following improvements.
1. There is a large uncertainty in the measurement of soft magnetic materials under DC conditions using the scanning method;
2. The definition of the basic hysteresis loop is proposed, that is, the point-to-point simulation impact method is used to measure the hysteresis loop of the material to ensure the uniqueness of the hysteresis loop and the relevant magnetic characteristic parameters Br/Hc/Bs/Hs;
3. Different materials use different impact times and impact waveforms. Only when the impact frequency reaches a certain requirement (slow enough), can the uniqueness of the hysteresis loop and related parameters be guaranteed.
Participated in the Coil Fair in Berlin, Germany in 2014, and was affirmed by international companies and foreign counterparts, and has begun to provide this device to well-known international companies, and has been exported to scientific research institutes and companies in the United States, Germany, Israel, Russia and other countries.
