The objective of this paper aims at investigating the feasibility of new coil winders with a spatial RSPC mechanism by conducting kinematic simulation. First, the design requirements and design constraints are specified based on the kinematics characteristic of coil winders. Then, the (4, 4) kinematic chains are obtained by number synthesis, and the atlas of feasible chains is generated. After that, the atlas of specialized feasible chains is found. Finally, new designs are obtained through the particularization process. In addition, an illustrated example of the RSPC mechanismselected from the new designs is given, and its feasibility is verified by performing kinematic simulation using ADAMS software. The result shows that it can meet the motion requirement of coil winders.
