NdFeB Magnet
NdFeB permanent magnet material is currently the highest performance permanent magnet material at room temperature. The NdFeB magnets developed by the Magnet Power team have been applied in many fields. Our understanding of the application of NdFeB allows us to calculate and design the most reasonable solution. The successful development of grain boundary diffusion technology has enabled us to produce NdFeB products with high performance （BH）max+Hcj ≥ 75, and achieved a substantial cost reduction.

T series Sm2Co17
T series Sm2Co17 magnets were developed by Magnet Power to be able to be used in extreme environments, for example, high speed motors and complex electromagnetic environments. They extend the upper limit of the temperature of permanent magnet from 350°C to 550°C. T series Sm2Co17 will present better properties when they are protected by high temperature resistant coatings in the temperature range, such as T350. When working temperature goes up to 350℃, the BH curve of T series Sm2Co17 is a straight line in the second quadran.

L Series Sm2Co17
L Series 2:17 samarium cobalt magnet is widely used in aviation, Marine, medical, automotive and other industries due to its low magnetic temperature coefficient. Br and BH(Max) of L Series changes a little with temperature rise. At present, we can produce L22 magnets in stable&massive production with Br≥9.5kGs,α(20-60℃) within 100ppm.

Magnetic Assemblies -High performance components
There are some special characteristics for the application of rare earth permanent magnets. First, to achieve the set magnetic effect, it is necessary to design a reasonable magnetic circuit and assemble the magnets. Second, permanent magnet materials are difficult to machine into various complex shapes, and secondary machining is often required for assembly. Third, it is necessary to consider various factors such as the strong magnetic force, demagnetization, special physical properties, and coating affinity of magnet. Therefore, assembling magnets is a challenging task.

High Speed Motor Rotor | Motors & Generators | Industrial Magnetic Solutions
High speed motor is usually defined as motors whose rotate speed surpasses 10000r/min. Due to its high rotate speed, smaller size, connected directly with prime motor,no deceleration mechanism,small moment of inertia, etc., the high speed motor has merits of high power density,high transmission efficiency, lower nise,economy of materials,fast&dynamic response and so on.
The high speed motor is widely applied for the following fields:
● Centrifugal compressor in air conditioner or refrigerator;
● Hybrid electric vehicle,aerospace,ships;
● Emergency power supply for critical facilities;
● Independent power or small power station;High speed motor rotor, as the heart of the high speed motor, whose good quality determines the performance of high speed motor.Looking to the future, Magnet Power has spent a great deal of manpower and material resources to build a assembly line of high speed motor rotor to provide customerized sevvice. With skilled engineers&techinitians, Magnet Power can manufacture massive diffrent kinds of high speed motor rotors to meet requirements of different customers.

Anti Eddy Current Assemblies
Under the trend of high speed and high frequency, NdFeb and SmCo magnets have low resistivity, resulting in eddy current loss and high heat generation. At present, there is no practical solution to substantially increase the resistivity of magnets.
By increasing the resistance of the assemblies , the Magnet Power team effectively reduced the eddy current effect, reducing heat output and reducing magnetic losses.
