Magnet Application-Wind Power
Sintered NdFeB magnets used in wind turbine requires high magnetic flux consistency, simple method and convenient batch traceability.
The magnet for permanent magnet wind turbines is generally square in shape, and its performance is most commonly 38H, 40H, 44H, 38SH, 40SH, 42SH, 38UH and other grades.
Direct drive wind turbine magnets requires high comprehensive performance to withstand harsh working environment and long service life.
Sintered NdFeB magnets with high magnetic properties are widely used in wind turbines and hydro generators. High Hcb helps to avoid non-magnetism at high operating temperatures.
Both types of generators need to work in harsh environments. They must withstand high temperatures, cold, sand, moisture and even salt spray. Therefore, the surface treatment of these magnets is very important.
Thus, we will recommend high corrosion resistance products, which is qualified after PCT or HAST tests.
Below are the weight loss test conditions:
PCT:120℃ 100%RH 2.0atm
HAST:130℃ 95%RH 2.7atm
