Electric Motor Retention Sleeves

Polar Technology have become a key supplier in the development of composite retention sleeves, for electric motor applications to maximise efficiency, performance and power density.
The composites sleeves, manufactured in a humidity and temperature-controlled environment on CNC winding machines, can be pressed onto rotor assemblies and work to retain the magnets in the rotor at the highest speeds.
To support this demand, we have also installed a brand-new 3-spindle filament winding machine, which forms part of a designated, world-class manufacturing cell. The features of this new machine include precision tension control, a 9 tow fibre delivery system and high-speed, 4 axis winding.
