Today Tecomag will talk about how the appearance defects of magnets affect the magnetic properties? Seemingly insignificant appearance problems, in fact, have a large impact on magnetic properties!

TECOMAG summarizes for you today: Smaller sintered ferrite magnets in smart door locks have the following application scenarios: sensor, electromagnetic drive, signal enhancement and anti-interference, NFC signal enhancement

Guys, today to say how to detect the intrinsic coercive force of NdFeb magnets, you can refer to the following methods:

In fact, after the surface treatment of Ndfeb magnets, there are usually some small changes in magnetic properties.

Guys, let‘s discuss a question today: Does the dimensional tolerance of sintered ferrite magnet affect the performance of smart door lock? The answer is yes! If the dimensional tolerance is not appropriate, it will affect the installation match of the smart door lock. May cause the installation is too tight or too loose, affecting the stability of the door lock.

Guys, today to talk about how to judge the quality of NdFeb magnets. First of all, you can start from the appearance, the surface should be smooth and smooth, no cracks, bubbles, these defects. The coating must also be uniform and dense with strong adhesion. The dimensional accuracy can not be sloppy.

Under normal use conditions: if the use environment is good, the work load is normal and properly maintained, its service life can reach 5 to 10 years or so.

First of all, you can start by optimizing the binder. Choosing a highly elastic binder is like putting on a shock-absorbing "coat" for ferrite, which effectively absorbs shock energy. At the same time, the strength of the binder is increased to make the ferrite stand more stable in the motor.

Discover what magnet Br (remanence) means, whether a higher Br value is better, and the significance of magnetic flux density.

Are arc magnets marked with N and S poles? Learn how manufacturers show polarity and request custom markings for magnetic tiles.

What is the black substance on the exterior of the bonded neodymium magnet? What type of coating is it? Additionally, which protective layers can be applied? What is the maximum operating temperature for bonded neodymium magnets? Today, we will address these questions.

1. NdFeB permanent magnet material is a type of permanent magnet based on the intermetallic compound Nd2Fe14B, which possesses an exceptionally high magnetic energy product and coercive force. The advantages of high energy density make NdFeB permanent magnet material essential in modern industrial and electronic technology.

Sintered ferrite has the following characteristics: 1.Magnetic properties: 1.Moderate magnetic strength: It has relatively stable magnetic properties, which can meet the requirements of many common applications. However, compared with some high-performance rare earth magnets, its magnetic strength is not extremely high. For example, in some medium and low requirements for magnetic field strength in motors and speakers, sintered ferrite can play a good role12.

Sintered ferrite has a wide range of applications, including: Electrical and Electronic Devices: Motors: Used in various motors such as automobile starter motors, fuel pump motors, fan motors, wiper motors, window swing motors, lifting glass motors in cars, as well as in motors for household appliances like air conditioners, washing machines, and dishwashers. Sintered ferrite magnets help in converting electrical energy into mechanical energy.
