This project is focused on the development of a new type of Continuously VariableTransmission (CVT) system that is widely applicable to the automotive and industrial sectors.CVT systems are becoming increasingly prevalent and have particular benefits in hybridvehicle drive trains where they used ensure that the engine is operating at its maximumefficiency at any point in the drive cycle and that the vehicle performance requirement issimultaneously met. By exploiting this flexibility, significant system efficiencies andfuel/CO2 benefits can be achieved.Magnomatics has previously developed a first generation magnetic CVT (mCVT1) and thissystem has been demonstrated to offer significant efficiency and packaging advantages overexisting technology and is currently the subject of two TSB funded collaborative researchprogrammes (under the LCV IDP and HVM programmes) with Ford Motor Company andVolvo Powertrain.By continuing the original research programme, acquiring accurate customer feedback andfostering internal innovation, Magnomatics have developed a second generation mCVT(mCVT2) concept that has the potential to reduce the use of rare earth magnet material by upto 75%, give increased part load efficiency, allow deletion of several elements to provide costsavings and deliver a system that can be realised in a much more compact space envelope thanthe first generation. If the predicted technical and commercial merits of this second generationare realised it will lead to a significant uplift in the adoption and value of MagnomaticsmCVT technologies.This project will rapidly deliver a working proof of concept of mCVT2 that will be validatedand evaluated on Magnomatics existing drivetrain dynamometer system. Once validated theconcept will be aggressively developed for typical vehicle drivetrains as a competitive system,potentially replacing, the first generation systems in the existing project group.
