Collaboration focused on increasing rate, accuracy and repeatability of high-tension winding solution for electric motors destined for transit applications
Cygnet Texkimp (Cheshire, UK) and Bowman Power (Southampton, UK) are collaborating to advance capability in high-tension carbon overwrapping of rotors used in electric powertrains for land transport applications.
The collaboration combines Cygnet Texkimp’s filament winding expertise and dedicated high-tension overwrapping solution with Bowman Power’s capabilities in developing advanced electrified turbomachinery for industries including rail, on and off-highway, and power generation.
The original solution was developed by Cygnet Texkimp to wind carbon fibre at high tension around the motor, adding an extra level of considerable strength and substantially increasing its capacity for rotational speed and endurance without adding significant weight, resulting in more power from lighter motors.
Bowman Power has acquired the winding technology and is working with Cygnet Texkimp to develop a dedicated solution to support customers across the transportation market. Together, they are developing the solution to increase accuracy and repeatability at rate and to optimise production of e-motors to meet the future needs of the market.
Gareth Davies, International Sales Manager at Cygnet Texkimp, said: “This project is driven by the transportation market looking for ways to improve the performance of electrification technologies – in particular, the search for a solution that increases the accuracy, efficiency and consistency of e-motors at high speeds.
“From the very beginning of our work with Bowman Power, it was evident that they were going to push the boundaries of performance in terms of the material, process and the final product. Collaborating with their programme and production teams has helped us to refine the offering supplied and provides an excellent base for future development. The technology offers a robust and reliable answer to a major industry challenge, and we believe it has the potential to become an industry-wide solution to electrification with many applications across the transportation market.”
Paul Dowman-Tucker, CEO at Bowman Power commented: “The team at Cygnet Texkimp have exemplified what a partnership should look like. We had very exacting requirements as to what we were trying to achieve and they measured up to, or surpassed, all of them. I’m thrilled with the new capability Cygnet Texkimp have enabled Bowman Power to bring online to help us deliver the world leading electrified turbomachinery solutions we are developing.”
