The company began work on its revolutionary DD PMG design in September 2014. Hugh-Peter Kelly formed a team of experienced electromagnetics engineers and set a project objective to design from first principles a new DD PMG that would:
Project results indicate that substantial cost savings can be achieved.
The University of Cambridge has developed a Finite Element Analysis (FEA) that has been used to validate project results.
My objective at the outset was to see if we could research, design and build a direct drive permanent magnet generator that could deliver comparable output at a comparable weight to existing generators. I was convinced that if we could accomplish this that we would be able to deliver significant cost savings. We have achieved our initial objective and have confirmed that ferrite magnets now provide a viable alternative for direct drive permanent magnet generators!
