EAS IX: David Calley’s Innovative Design and Use of Electric Motors

David Calley is  member of the CAFE Foundation Advisory Board, with a great deal of technical expertise to offer.  His small wind turbine sold over 150,000 units.  His patented design for the TrailerTail® increases fuel economy on semi-trucks and trailers by 5.4 percent at 65 miles per hour, according to SAE tests.  Last year at EAS VIII, he showed the potential for small motors with incredible torque that could power Sky Taxis. At this year’s EAS IX he described, in depth, the type of motor design he has been developing to power things like his three-wheel electric/pedal-powered commuter vehicle and landing-gear wheels on Sky Taxis and even rocket fuel pumps. He asked the not-too-rhetorical questions, “How high can electric motor power go?” and “Where do these forces come from?”  His answers took attendees on a high-level look at electromagnetic and permanent magnet (PM) materials theories. Electric motors rely on interactions between fields to produce power.  “Fields” in this case are …
