How to test the permeability of permalloy material u0.08 by scanning method?

How to test the permeability of permalloy material u0.08 by scanning method?

Under the condition that the demagnetization control of the equipment is very good (the requirements of demagnetization quality should be added to the relevant IEC and GB standards), the initial permeability ui can be easily extrapolated by the impact method, and the Rayleigh constant of the material can be calculated more accurately. Similarly, the scanning method is used to test several sets of hysteresis loops under weak magnetic fields, take the corresponding maximum magnetic conductivity, and calculate the initial magnetic conductivity ui. This will fill the gap in the initial permeability test for DC magnetic properties measurement of soft magnetic materials. Finally, Hs are 8A/m, 0.8A/m and 0.08A/m three hysteresis loops together, the Rayleigh zone is very small!

Multi-pole magnetic ring pole width test assessment

Multi-pole magnetic ring pole width test assessment

In order to satisfy foreign users to investigate the testing capability of Yongyi Science and Technology FE-2100RMD's multi-pole magnetic ring, a more detailed testing experiment was carried out, and the data were analyzed and summarized, basically achieving the ideal effect. Through the experimental summary, the product can be used as a test standard for reference in the later period, so as to ensure the accuracy and consistency of product testing while mastering its own product testing capability.

Guide for magnetic distribution meter

Guide for magnetic distribution meter

The multi-pole magnetic ring magnetic field distribution measuring instrument (or magnetic wave measuring instrument) is an indispensable tool for the production of multi-pole magnetic rings or rotors in the motor industry and the quality inspection of magnetic rings in related motor enterprises. As early as the late 1990 s, the relevant patent design report of this equipment was carried out in China (Shandong native: Lao Meng). In the past 10 years, about 10 domestic enterprises have begun to produce the functional products. Through the understanding of foreign related products, it is found that there are not many manufacturers of such measuring devices abroad, mainly less than 10 enterprises in Japan, South Korea and Germany. Why do users have urgent needs of products, compared with other measuring equipment related technical content is not high, but can not be well accepted by users? Where are the uncertainties? I through the understanding of users in the same industry, and the use of the same magnetic ring in different manufacturers of magnetic field distribution measuring instruments to test the same product, found some problems, here to share with the industry, hoping to help everyone.

The magnetic properties of permanent magnet materials and the indicators it includes

The magnetic properties of permanent magnet materials and the indicators it includes

The main magnetic properties of permanent magnet materials are: remanence (Jr,Br), coercivity (bHc), intrinsic coercivity (jHc), magnetic energy product (BH)m. What we usually call the magnetic properties of permanent magnet materials refers to these four items. Other magnetic properties of permanent magnet materials include Curie temperature (Tc), working temperature (Tw), temperature coefficient of remanence and intrinsic coercivity (Br θ,jHc θ), recovery permeability (μrec.), squareness of demagnetization curve (Hk/jHc), high temperature demagnetization performance and uniformity of magnetic properties.
