CFRP bandages and sleeves for electric drives

From prototypes to complete series production. We develop and manufacture CFRP sleeves and bandages made of carbon materials optimized for highest speeds – increase performance and efficiency with our scalable production.

Why composite fiber bandages / sleeves?

  • Very high strength and rigidity with minimum weight, enables a motor bandage for high-speed ranges that cannot be achieved with metal bandages.
  • Due to the lower thermal expansion, the preload is maintained by the sleeve. The motor does not lose power.
  • Steel sleeves can generate ‘unwanted’ eddy currents, which can have a negative effect on the performance of the motor.

Advantages from CFRP bandages & sleeves from the Connova Group

CFRP sleeves and bandages are revolutionising the manufacture of electric drives with advanced carbon fibre technology that promises first-class efficiency and reliability. Developed using innovative production methods, they offer outstanding performance characteristics and are efficient and reliable even under extreme conditions.

Manufacturing technology for CFRP bandages & sleeves

Our CNC filament winding technology is ideal to produce rotationally symmetrical tapes and sleeves. The endless carbon, glass or aramid fibres are impregnated with resin under CNC control and placed on a rotating tool mandrel. The winded tube is then cut to length according to customer specifications and further processed into the finished component using CNC grinding. The Connova Group works on 2 winding machines – with 4 programmable axes – which allow us to process components up to dimensions of 7 meters, max. Ø 1300 mm. We process over 100,000 components per year on our CNC-controlled winding and grinding machines.
