Study on high precision winding of toroidal coil and automation of its process

Abstract

This paper deals with high precision coil winding machine for toroidal cores. This winding machine has new winding mechanism, which consists of new shape winding ring and wire save ring proposed in this study. The mechanism gives the machine ability of tension control. Kink prevention equipment is designed to avoid kinks while winding. These improvements make high precision winding possible. This machine is better than machines currently in use, specially for small size core and automation of its process.
