Magnetic continuously variable transmission for heavy-duty vehicles

磁性无级变速器（mCVT）的原型将开发用于重型车辆的应用。2010年，magnnomatics公司成功展示了mCVT （trl3 /3）的概念验证，其功能可以使乘用车发动机在其最高效率区域内运行，并为车轮提供变速驱动。与传统的传动系统相比，这种新型的mCVT具有明显的优势：高效率（峰值99.5%）、紧凑、无接触和无润滑、无级变速和固有的过扭矩保护。mCVT是一项重要的发明，在性能和功能上有了一个台阶的变化，适用于乘用车，商用车，风力涡轮机和许多工业系统。所有行业的商业成功都取决于先进制造技术的发展，以实现稳健、经济、批量生产。值得注意的是，这些先进的制造技术也将使相关TSB项目开发的磁齿轮牵引电机的成本降低和批量生产成为可能。该联盟打算解决主要的工程挑战，并指定、设计、建造和测试成本优化的mCVT，并展示英国专业制造商如何增加主要价值。

A prototype magnetic continuously variable transmission (mCVT) will be developed for a heavy-duty vehicle application. A proof of concept mCVT (TRL2/3) was successfully demonstrated in 2010 by Magnomatics, with functionality to enable a passenger car engine to operate within its peak efficiency region and give variable speed drive to the wheels. This novel mCVT provides clear advantages over traditional transmission systems: high efficiency (>99.5% peak), compactness, contactless and lubrication-free operation, infinitely variable transmission and inherent over-torque protection. The mCVT is a significant invention that gives a step change in performance and functionality, suitable for use in passenger cars, commercial vehicles, wind turbines and many industrial systems. Commercial success for all sectors depends on the development of advanced manufacturing techniques to enable robust, cost-effective, volume manufacture. Significantly, these same advanced manufacturing techniques will also enable cost reduction and volume manufacture of magnetically-geared traction motors developed in related TSB projects. The consortium intends to address the chief engineering challenges and specify, design, build, and test a cost-optimised mCVT and demonstrate how the principal value is added by specialist UK manufacturers.
