Gudhi Engineering ha developed a special purpose machine for DUCATI to simultaneously impregnate three stator windings of fly wheel magnetos with a specific resin. Each stator is prepared outside the machine and wired on a mechanical interface having a suitable but fixed three way quick connection system that snaps in to the main rotating shaft.The stator rotates by means of a variable speed brushless or stepper motor. The drives to all stators are operated by means of belt and pulley.
The stators are heated to defined temperatures Impregnation is performed by dipping them into an impregnation tank that is filled with heated resin. Impregnation is carried out when the stators are rotating. This operation achieves uniform impregnation level independent of impregnation time and stator volumes. After impregnation, curing is performed at a suitable current word.
