Besides Neodymium magnets and magnet assembly, MaximMAG is also marketing lot of other magnetic materials at a good price and quality, rubber magnets is one of them.

Rare earth Upstream over-capacity exacerbate, the industry calls for strengthening management on sources

          On the 7th China Baotou rare earth industry forum, an insider pointed out that the rare earth upstream over-capacity has exacerbated in last five years, this has greatly effected the healthy development of the industry, in order to turn the tables strengthening management on sources is a must.

         Mr. Chen zhanheng, Vice Executive secretary of Association of China rare earth industry, said that over-capacity had long troubled the development of rare earth industry in China, before 2011 the capacity of the rare earth upstream products was from 0.18 million to 0.2 million tons, while when it flurished in 2011 and an investment boom in rare earth was happened, the capacity reached 0.3 million tons just at the end of the year 2011. An estimated 0.4 million tons rare earth upstream products' capacity was reached in 2014.

 

         Mr. Zhang anwen, vice executive secretary of Chinese Society of Rare Earths, said excessive competition due to large capacity of upstream products currently is seriously affect healthy development of the industry. For example: from July of 2011, our rare earth products experienced continuously falling on prices, most products' prices has fallen more than 70%, some even more than 80%. Currently lot of key rare earth companies are at a loss.

 

         The insider point out that over-capacity exacerbation is one of the main reasons why the rare earths' prices still goes down under an environment of continuous integration of rare earth industry. It is suggested that at the same time of pushing forward industry integration and intensify fighting against rare earths "black industry chain" , management on rare earth mining should be further strengthened.

Neodymium Magnets in bridge shape

According to client's requirements, MaximMAG made a bridge shaped neodymium magnetic block to hold the small ceiling lamp. Although it is very small, it has great magnetic pulling force, as you may come to know MaximMag's residual magnetism of magnets can reach to 14.8 kGs.

Permanent magnet synchronous traction motor magnets

Using high-performance rare earth permanent magnet materials, no carbon brushes, permanent magnet synchronous gearless traction machine can drive efficiency up to 90%. It effectively improves the energy efficiency with energy saving, environmental protection, low speed and high torque characteristics. Gearless traction machine can be dividedinto the inner rotor and outer rotor based on the rotor structure, while permanent magnets stick to these rotors.

Due to the special work environment of the elevator, it is possibility that magneton the motor will demagnetize after prolonged use, for example:
1. Unqualified rare earth permanent magnet;
2. Unsaturated magnetization;
3. Motor working temperature exceed magnet permitted range;
4. Long oxidation of rare earth permanent magnet;

In orderto avoid the above situation occurs in practice, the elevator magnets needs careful and meticulous design and manufacturing. Magnet design also needs to consider magnet size, magnetic properties and the worst working conditions of motor. It is better that the magnetic properties are higher than the practical requirement. Before installation, rare earth permanent magnets should pass high temperature aging test and saltspray test.

For a long time, elevator manufacturers use bonding process to fix permanent magnets on the rotors. Theoretically, using glue and magnetic force, it could be okay. But In some cases magnets will tear off because of high temperature or other reasons. To reinforce magnet on the rotor and reduce the problems caused by magnet dropping, it can combine screws and adhesive binding by making a countersunk on the basis of simple block or arc magnets.
