Sheensen Technology applies itself into the development and stable production for Automotive motor magnet and Wind turbine magnet. The high-consistency and low-temp . coefficient magnet of multi-grade and multi-type are already in mass product. As for SHT series wind turbine magnet with big dimension in mass production, the magnetic-flux fluctuation range＜±1%; 120℃ X 2h average heat demagnetization rate＜1%;
As for 38UH-38AH series Automotive motor magnet in mass production, the temperature coefficient of Coercivity in the range of 20-150℃ of 38UH can be down to -0.47%/℃ and it can continue working over 2000hrs in the cold and hot shock environment of Temp ranging -40℃～160℃.
As for 38AH series product, Temperature Coefficient of remanence in the range of 20-150℃ can be down to -0.09%/℃, and the Max. working temp. can be up to 240℃.
The picture on the left is the micro-structure of 42SHT wind turbine magnet. The particle size is in high consistence, no neodymium rich phase agglomeration among particles, which lays a good foundation for the low temp. coefficient, low weight loss and high-consistence of the magnet.
