Neodymium Permanent Motor Magnets Manufacturer China Rare Earth Magnet Limited

Nowadays, in general, permanent magnet motor is the support of modern new technology and industries. Combined with power electronic technology and microelectronics control technology respectively, there are various high performance mechatronic products, like numerically-controlled machine tool, robots, EV, laptops and so on. Gradually, the development of this industry has the tendency as below:

1)    Energy-saving
As a matter of fact, the PM motor with neodymium permanent magnets can save electricity for 10% to 20% on average. To be more energy-saving, on the one hand, is to change the structure of asynchronous motor to improve its efficiency and performance. On the other hand, it is to develop PMSM greatly, in order to achieve greater effect.


2)    Mechatronics
To advance the traditional mechanical and electrical products, mechatronic is the key point, among which the permanent magnetic motor is the foundation, such as servo motor for numerically-controlled machine tool, VCM for computers, etc.

3)    High-performed
Various modern devices require more and more superior performance to motors. For example, the military equipment asks for motors which can provide accurate signals.

4)    Specific
As the load of motor is changeable, it is improper to use universal type in some situation. Actually, specific motor accounts for 80%, while universal type only 20% in other countries. However, it is opposite in domestic market. So it is necessary to develop more specific product.

5)    Light-weighted
Now, various sophisticated and tiny products like medical equipments are developed rapidly, correspondingly, the matched motor should also be more light-weighted and small-sized.

China Rare Earth Magnet Limited manufactures permanent motor magnets with different materials like neodymium NdFeB magnets, SmCo, Ferrite, etc.
