While at the beginning it was not welcomed with great enthusiasm, today the idea of replacing an iron stator with a light PCB one is achieving a new prospect. Lightening the stator means attaining more motor efficiency, therefore fewer emissions and electric energy consumptions.
In 2012, there was already feasibility evidence, when Boulder Wind Power integrated a PCB stator into a direct-transmission generator with 12-metre diameter for a wind turbine that produces 3 megawatts of power and slightly more than 2 million Nm of torque.
The Texan Infinitum Electric has a lot to say about this issue, having developed a PCB stator motor that suits a broad variety of purposes and generates the same power as a conventional alternate current induction motor, but with half weight and sizes. Now, the specific motor is finding applications such as HVAC and electric vehicles.
