12m ring generator passes prototypes tests, edges closer to production

摘要

Early last year, this magazine reported on a prototype generator that would use production methods developed for printed circuit boards to take cost and weight out of a permanent-magnet generator for direct-drive wind turbines (WPE&D, Feb 2012).The 12-m diameter ring generator and power-conversion system were electrically segmented so we could run a variety of critical tests at full-load while minimizing the investment required for multiple design iterations of the electrical system," says Boulder Wind Power's Co-Founder and Chief Technology Officer Sandy Butterfield.
