Product Description
The N38EH NdFeB magnet has excellent temperature resistance, the highest working temperature can reach 200 ℃.
Large permanent magnet wind turbines typically use thousands of neodymium magnets. Each rotor contains many magnets. Wind turbines usually operate in the wilderness and are subjected to high temperatures and cold. At the same time, motor losses cause motor temperatures to rise. NdFeB magnets of EH-series can work at high temperatures.

Block Neodymium Magnet Advantages
1.Material
The performance parameters of sintered NdFeB magnets mainly have three key magnetic properties including remanence (Br), coercivity (Hcb, Hcj ), and maximum energy product (BHmax). Their magnetic fields have a very high intensity, they are very resistant to demagnetization, and a very high-energy product.
2.World's most precise tolerance
±0.02mm ~ ±0.05mm
3.Coating / Plating
Options: Nickel (NiCuNi), Zinc (Zn), Black Epoxy, Rubber, Gold, Silver, etc.
The nickel plating is actually triple plating of nickel-copper-nickel. The combined thickness totals 15-21μm.
4.Magnetic Direction: Thru Thickness
Block magnets are defined by three dimensions: Length, Width and Thickness.
The regular magnetic direction of block magnet are magnetized through the length, width, or thickness.
