History and application of permanent magnets

Rare earth permanent magnets were developed and applied earlier. They use iron and iron group elements as important components of alloy permanent magnet materials. They are also called permanent magnet alloys and mainly include alnico permanent magnet alloys, iron-chromium permanent magnet alloys and platinum-cobalt permanent magnets. Magnetic alloy.

As an upgraded product of electromagnets and permanent magnets, electric permanent magnets are more expensive than electromagnets, but only by cutting off the power supply without losing their magnetism and having many performance advantages of adjustable magnetic force can they be completely superior to electromagnets. This is also increasingly The main reason why many machinery manufacturers use lifting permanent magnets to transport workpieces. So, in workshop production, how does the lifting electropermanent magnet control the magnetic force and the size of the magnetic force? Next, let us take you to find out.
As an upgraded product of electromagnets and permanent magnets, although the cost of permanent magnets is higher than that of electromagnets, it is only an electromagnet (the electromagnet will not lose magnetism due to sudden power outage when using it, and the workpiece will not be affected by sudden changes when lifting materials. Falling due to power outage. The safety factor is a qualitative leap). Because of some shortcomings of use, we have ideas and motivation to improve them. The expansion of every industry is a technological competition, and every new product is an industry adventure. Contemporary society advocates innovation as the driving force for development. Innovation is development, innovation is the future. When it comes to technological innovation, the key is to rely on technological innovation to transform development momentum - people are inert, and materials are inert. An old and normal way, a simple and widespread way of development is not sustainable.

To sum up, compared with ordinary electromagnets, the safety factor of magnetoelectric lifting permanent magnets has made a qualitative leap, and it is currently a relatively safe and reliable environmentally friendly lifting equipment.

The sharp increase in installed wind power capacity has driven the demand for NdFe. As the installed capacity of wind power increases, the penetration rate of permanent magnet direct drive generators increases. The demand for NdFeB for wind power generation in 2025 may reach tens of thousands of tons, several times the demand in 2019. Permanent magnet direct drive wind turbines will gradually replace doubly-fed wind turbines and expand the application of high-performance NdFeB permanent magnet materials. Most direct drive wind turbines are permanent magnet synchronous generators. Due to the advantages of low maintenance cost and high system efficiency, there is a trend of gradually replacing doubly-fed fans. High-performance NdFeB magnetic materials are widely used in permanent magnet direct drive wind turbines. Increasing the penetration rate will increase the market space of high-performance NdFeB magnetic materials.

Install the electro-permanent magnet at the end of the truss robot or robot arm, and give the electro-permanent magnet a short magnetic charging signal (about 0.01-2 seconds). The electro-permanent magnet is magnetic. At this time, the electro-permanent magnet can absorb multiple workpieces at one time for transportation. Compared with traditional handling, it improves work efficiency, reduces workers' labor intensity, and helps the workshop develop towards automated production.
