随着所有强调风力的重要力量是对能源供应的未来，对我来说，我们没有看到各种专用发电机设计。有一些，但只有少数人。也许这是因为发电机设计的磁石不是工程学学校的流行主题。很难找到一个在这个主题上了解的物理教授。
考虑基本的操作要求。水平风转子以低速转动，通常在7到23 rpm之间。当行业规范为1200至1800 rpm时，电动机或发电机的电动机或发电机非常低。
Basically the wind industry has attempted to take existing generator designs at 500kW and above and make them work, even though wind power is not what those machines were designed to do. Using an “off the shelf” generator would make sense during early prototyping to avoid the expense of producing a new generator design. But where there is ongoing manufacturing, GE claims to have 16,500 turbines installed, the investment would be justified.
The power electronics guys are having to deal with the exact same problem when it comes to making inverters for the wind industry. Turning dc power into 60 cycle ac power is not news, but having wildly varying input power changes the solution dramatically. There are dozens of suppliers in the solar market with inverters 500kW and up to 2MW who have successful solved this problem for their markets.
To come up with a unique wind generator requires a clean sheet of paper. Just as Tesla insisted on it’s own custom motor with copper bars to increase driving range, the solution to a generator for the wind industry is starting from scratch and focusing on the needs of the application.
Boulder Wind has a large diameter circumferential generator that is high pole count so it can be directly driven by the propeller blades of a standard horizontal wind turbine. The design uses air cooled permanent magnets that are lower in cost than the magnets used in servo motors. The new unit is already showing increased efficiency in early testing and should be on the market by 2017.
从早期测试4MW PM直接驱动风力涡轮机到10MW超导发电机，通用电气一直在展示工业的高柱数发电机解决方案。在陆上和海上应用的最早和最具创新性设计中，这些系统消除了齿轮箱成本，重量和惯性，使得直接驱动风力的显着改善。
These improvements are all the result of the same thing; Motor Centric Design, examining the application of a motor or generator and looking for optimized solutions.
