Final Form Winding Machine Is a First
ROTARY ENGINEERING has designed and built the first ever ‘final shape’ winding machine to wind and form round wire diamond coils in just one process. When a leading UK motor repair business won a high-volume contract, they needed to be able to manufacture coils as efficiently as possible.

Rotary’s engineering team took up the challenge by looking at the problem from first principles, and the final form winding machine was developed. The new machine has been in service for a number of months and has proven to be highly efficient and reliable with excellent repeatability.

Creating an accurate former, able to guide multiple wires into the final form, required some innovative design work and several iterations were produced before the optimum shape was developed. Working from coil drawings, formers were developed and produced using 3D printing technology. Trials took place at the company’s Sheffield factory, where the machine was thoroughly tested prior to despatch. The machine incorporates touch screen PLC control with fully variable speed and accurate turn count with automatic stop.

Commenting on the new product, Simon Swallow, Managing Director at Rotary Engineering, said: “We are keeping up to date with developments in motor technology and regularly contribute to design groups working on research in this area. This allows us to share our experience with others, and it ensures we are up to date with future requirements. This project was a perfect example of bringing together our experience with new innovative methods of manufacture to give our customer a great outcome.”
