Direct Drive AC Rim Motor for Responsive Energy Control of Alternative Electric Vehicle

The purpose of this project is to investigate environmentally sustainable and safe solutions for alternative vehicles by applying an innovative direct drive power train to a competition model Society of Automotive Engineering (SAE) Formula Electric Vehicle. The project will meet the goal of Environmental Sustainability by increasing the range and efficiency of an electric vehicle through improved regeneration capabilities and an innovative lightweight "rim motor" topology that converts energy closer to the point of use, thereby making electric vehicles more attractive. This design displaces normal auto emissions to the power generation sector, where the energy can be supplied by renewables or in such a manner that emissions can be more cleanly handled. The project will meet the goal of Safety by allowing for true four wheel direct drive which improves vehicle turning radius, shortens braking time, prevents sliding due to loss of traction, and places both drive torque and regeneration directly at the wheels.
