传统的小型风力发电机由于使用风车叶,因而需要较大的空间运作,要远离人口稠密的地区。
Conventional small wind turbines are designed to have rotor blades, which require large Spaces to operate in and need to be located away from populated areas.
The performance of small type of permanent magnetic wind power generator can be analyzed reasonably in one exact testing system, which will direct optimization and design.
