• 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.

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.
