500w home wind turbines

A wind turbine, which is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home¡¯s electrical system.

In a normal residential application, a home is served simultaneously by the wind turbine and a local utility. If the wind speeds are below cut-in speed (7-10 mph) there will be no output from the turbine and all of the needed power is purchased from the utility. As wind speeds increase, turbine output increases and the amount of power purchased from the utility is proportionately decreased. When the turbine produces more power than the house needs, the extra electricity is sold to the utility. All of this is done automatically. There are no batteries in a modern residential wind system.

Small wind generators systems for remote applications operate somewhat differently, and it needs batteries.

2. Structure and Main performance

wind turbines are made of strong cast steel that makes them durable.
small wind turbines  can withstand harsh environments like strong winds and cold weather. Using high performance NdFeB permanent magnet, the alternator is high efficient and compact. The unique electro-magnet design makes the bonding force and cut-in speed very low.
