Hangzhou Magnet Power Technology Co., Ltd. products

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.

Sintered NdFeB is made of PrNd, Fe, B, Cu, etc., having excellent magnetic properties, strong machinability. We have the whole process of manufacturing capacity, including “ingredients – melting – powder – molding – sintering” . Our company is the outstanding supplier in producing NdFeB with high performance, such as N56, 50SH, 52SH, 45UH, 42EH, 38AH.

Mass production of high-performance NdFeB magnets with magnetic properties (BH) max+Hcj≥75, such as grades of G45EH, G48EH, G50UH, G52UH. Cost of GBD magnets is lower than that produced by conventional technology by more than 20%.  Magnet Power team has developed both spraying and PVD processes. And we have mature technological processes and strict management systems. The GBD technology is suitable for NdFeB materials with a thickness of less than 10mm.

1:5 SmCo is the first generation of rare earth permanent magnet materials. Compared with the second generation of 2:17 SmCo permanent magnet materials, it is easier for saturated magnetization and post-magnetization.

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.

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.

The vacuum aluminum coated Magnet magnet, designed and manufactured by Hang Zhou Magnet Power, offers incredible strength and durability. Its unique construction ensures that it can withstand even the most demanding conditions, making it an ideal solution for a wide range of industrial and commercial applications.

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.
