PCB Stator offers 30% cost reduction in wind power generation

Gone are the days when you had to wrap iron with copper coils to create electro-magnets. Boulder Wind Power, a Colorado based startup has created a printed circuit board stator. The engineers at BWP have printed the copper stripes on fiber glass and laminated the layers of these fiber glass together to create a stator that looks like a PCB. The company claims that this allows proven, highly automated, quality controlled stator manufacturing and better winding reliability. This approach to stator building allows lighter generator and eliminates the costs of building a heavy foundation and tower. A 3 MW turbine is approximately 40% lighter than most common turbines used these days.
