Abstract

The power confluence of increasing speed is realized prior to merging multiple input shafts with the same power into a single output. A new type of power-confluence magnet planetary gear (PMPG) transmission structure is proposed, and a design scheme of power confluence is given. By establishing a PMPG simulation model and combining the dynamic finite-element method with the response surface method, the relationship between the main structural parameters and transmission efficiency is optimized. Results show that an optimized structure can effectively reduce eddy current loss and improve transmission efficiency under the condition that the radial length of the structure remains unchanged.
