As an example of multi-motor synchronized driving system, the mechanical struct ure of a dual-motor synchronized driving system and the mesh relations between gears are studied. By mechanism analysis method, the dynamics principle of gear mesh and dynamics of multi-motor synchronized driving are analyzed. Ideal model of the dual-motor synchronized driving system without backlash is built by converting parameters on motor sides to those on load side. By analyzing back lash property, dynamics model of dual-motor driving system with backlash is bui lt. Structure diagrams and state functions of the system are presented. The gene ral dynamic functions of the multi-motor synchronized driving system with backl ash are deduced.
