Permanent magnetic materials (magnet) knowledge popularization
At present, the common permanent magnetic materials are ferrite magnet, NdFeb magnet, SmCo magnet, Alnico magnet, rubber magnet and so on. These are relatively easy to buy, with common performance (not necessarily ISO standards) to choose from. Each of the above magnets has its own characteristic...Read more -
What permanent magnets can be made of?
In fact, it is really widely used: In fact, are widely used: permanent magnet motor, magnetic crane, magnetic chuck, magnetic actuator (synchronous transmission, hysteresis, eddy current drive), magnetic spring (The curve is opposite to the spring shape when they’re attracted), security sen...Read more -
Xinfeng magnetic material radiation multistage magnetizing permanent magnet production efficiency is high, product quality is stable and reliable
The production process of radiation oriented sintered NdFeb magnetic ring is characterized in that it includes the following steps:(1) The lower pressure head assembly back to the edge of the Yin model cavity, the upper pressure head assembly up to the high; (2) The magnetic powder into the cavit...Read more -
Analysis of Bonding Failure of Permanent Magnet Synchronous Motor Rotor Magnet
Xinfeng Magnetic Materials Co., Ltd. has found and summarized through the experience of co-designing with customers for many years: There are many factors for the failure of the permanent magnet synchronous motor rotor magnet bonding, and most of them are in the process. For the permanent magnet ...Read more -
How do you make your own permanent magnet?
The non-homogeneous mix of magnetite, iron, oxygen and other trace elements in lodestone, the only naturally occurring magnet, is what makes it permanent (hard). Pure homogeneous magnetite or iron is not permanent but a temporary (soft) magnet. An ideal permanent magnet is a heterogeneous alloy w...Read more -
General questions about magnet applications
1.If you need high performance magnet, of course, choose Neodymium magnets. However, there are many comprehensive factors to consider about the application of magnetic materials. Therefore, it’s not easy to choose a high performance that means fine, we suggest you to provide your application for ...Read more -
Analysis and determination of thickness and air gap length of magnets in motors
The magnetic field of the motor is generated by the magnets in motors. The greater the working flux produced by the magnets, the total number of armature conductors required by the rotor can be reduced correspondingly, which is very beneficial to the motor. On the one hand, the armature resistanc...Read more -
Discussion on the effect of magnetic steel blank pressing technology on the properties of finished products
Occasionally there are very professional customers asked about the problem of permanent magnet blank pressing, then I will talk about the impact of pressing on the quality of the blank, I hope to be helpful to friends who are interested in understanding. Now magnet factories are using isostatic p...Read more -
