  •  Description: 

These arc segment magnets used to be applied into permanent magnet disk-type synchronous motors assemblies for small size wind turbine. It can be glued to the flux return steel plate or fixed with screws by countersunk holes.

Besides, the rotor magnets will be corrosive and lead to different proportional weight loss, when working under high temperature, humidity, atmospheric conditions. While wind turbines are used to settled down by sea side or desert, it needs Hast NdFeB Magnet to keep the generator working for durable life. Awesotech Magnetics can produce this kind of Hast Magnets with lower than 2mg/cm2 weight lose under 130 ºC±2ºC, 95% humidity ,2 atmospheric pressure for 100 hours.

When exposes the magnet under different temperature, humidity, atmospheric condition, the magnet will be corrosive and lead to different proportional loss of weight.When exposes the magnet under different temperature, humidity, atmospheric condition, the magnet will be corrosive and lead to different proportional loss of weight.df When exposes the magnet under different temperature, humidity, atmospheric condition, the magnet will be corrosive and lead to different proportional loss of weight.
