Market Analysis of Rare Earth Permanent Magnet Motor of 2014

One of Leading China Magnet Manufacturers – China Rare Earth Magnet Limited

Brushless DC motors are the products combining modern material science, electric power science and motor controlling theory. Rare earth PM motors are using magnet filed that produced by neodymium permanent magnets materials to replace magnet field produced by excitation current of traditional motors, make PM motors simplified, reliable, small, light, and efficient, with low energy consumption. Because of various appearance and size, NdFeB motors have fast development.

Development and application of rare earth permanent magnet synchronous motors expands the application of diversified sectors of PM synchronous motors, with its salient features of light type, high performance, high efficiency and energy conservation. High-performance neodymium iron boron magnets are the basis of new technology and high-tech industry. It combines with power electronics technology and microelectronic controlling technology, which can manufacture all kinds of electromechanical products with high performance, such as NC machines, machining centers, flexible production lines, robots, electric mobile, high-property household appliances, and computers and so on.

Development and application of NdFeB permanent magnet motors enter new level, with improvement of heat stability and decay resistance and decline of price and enhancement of technology of electric power and electric device. It gradually broadens new areas of high power, high property and mini type.

Neodymium magnets develop rapidly domestically, with rich sources of rare earth, improving quality and declining cost of permanent magnetic material, which is the fundamental of manufacturing PM motors with great power, giving us competitive edge both in domestic and international market.

In January to May in 2014, industrial output value of permanent magnet motor industry has reached 15.562 billion, rising 24.2% year on year. In 2013, industrial output value of motor industry had reached 28.86 billion, rising 17.2% year on year.

After China joins WTO, among domestic various industries, neodymium PM motor industry is strongly impacted by imported products. In 2014-2018, brand structures of sintered NdFeB magnets will possibly have a big adjustment. Sales of foreign brands will gradually fall off, while sales of domestic brands will rise steadily. Now, it is a special developing period of PM motors. With promotion of first-line brands, brand concentration will be higher and higher. But if the third or fourth-line brands don’t pay much attention to the terminal image and improvement of self brand, they will fade away gradually from the production stage.

On the other hand, homemade neo permanent magnet motors have some obvious advantages in some other aspects. Due to the long period of imported NIB PM motors, homemade ones are much more flexible. And besides duty and freight cost, homemade motors have superior advantages.

According to Report of China Rare Earth PM Motor Industry 2014-2018, the ability of market adapting is becoming stronger and stronger. We have the advantages of low cost of labor force and skilled worker. With the development of rare earth magnet, we now already have industrial supporting ability, excellent service level and stable industrial environment. All these are favored by the international buyers, which are irresistible advantages. Meanwhile, enterprises of permanent magnet will expand export, increase market share. This industry is becoming mature.

China Neodymium Rare Earth Permanent Magnets Manufacturer

Neodymium permanent magnet can bring smaller motors and generators with higher property, but its problem is that its manufacturing process is expensive and multi-step.

Researchers from Northeastern University declare that they have invented a cheap and green manufacturing process with only one step to produce SmCo magnet. The decline of manufacturing cost of strong magnets will bring a new type hybrid automobile with smaller and cheaper motors. Also, it enables permanent magnets to be used in field of aerospace and aviation.

C.N. Chinnasamy, the chief scientist of Microwave Magnetic Material and Integrated Circuit Centre of Northeastern University, announced that SmCo with the strongest property among rare earth magnetic material can be manufactured by recyclable chemicals. This manufacturing process can be applied to mass production, and its manufacturing cost will be cheaper than that of existing manufacturing methods.

Chinnasamy says: “China permanent magnet can be used in small motors and generators with high property which can work under high temperature environment, which is quite important to NASA and the Ministry of Defense. With this manufacturing method, this material can bring economical manufacturing cost.”

Chinnassamy carries out this research under the leadership of Vincent Harris who is the director and chief researcher of this research centre.

Harris proclaims that SmCo magnet is suitable for use in aviation turbines because its temperature is too high for other rare earth magnet. Not only is the cost of Chinnassamy’s one-step manufacturing process cheaper, but its chemicals used for producing SmCo permanent magnets is recyclable and environment friendly. Therefore, it is very suitable for use in large-scale production.

These researchers invented nanotechnology to manufacture these rare earth magnets which can displace other existing expensive and multi-step metallurgical technology. Among existing methods, metallurgical technology fuses Co and Sm with accurate proportion, but they have to be fused under vacuum environment in case of oxidation, which greatly increase the cost.

According to USA Northeastern University, Sm and Co, with accurate proportion, dissolve in a kind of high temperature solvent. During the dissolving process, they produce magnet nanometer blocks, extremely tiny doublets whose size is only10x100 nanometer, subsiding at the bottom of the solvent. Then, they cover PVP which can avoid oxidation on nanometer blocks with black magnet powder forming. This magnet powder can become strong permanent magnet in strong magnet field.

Other method, used for producing nanometer block doublets, also can work successfully under high temperature, but under room temperature, property of this rare earth magnet will be poor. However, researchers of Northeastern University declare that, their methods can work well no matter it is under room temperature or high temperature, which can, therefore, bring small motors equal large engines.
