The Motion CVT provides a very useful alternative for applications requiring continuous speed variation. It is a compact and efficient design that could easily be adapted to numerous configurations. Test restults show that the 42 degree flat faced discs offer a higher overall efficiency because of the reduction in contact patch spin. However, these discs do require a higher axial loading, which will lead to higher bearing losses, depending on the support and loading mechanism employed. Additionally, efforts to predict the performance of the Motion CVT by means of analytical models have proved successful. Currently, the model shows good agreement with both efficiency and axial load over most of the speed ratio range. Similar studies, not presented here, at higher torque have also shown good agreement. Overall, the model provides a very useful tool for evaluating the performance of the Motion CVT and considering design alternatives for boosting efficiency. Further, the intrinsic characteristics of the model are such that it can be adapted to a wide range of operating conditions for almost any traction dive configuration.
