Rotor assemblies of electric motors are provided with a synthetic fibre bandage, unless a cage-like construction has been selected. Glass fibre filament is wound over the glued magnets. Afterwards, the wound bandage is impregnated with heat curing epoxies or UV-curing adhesives.
The adhesive is applied while rotating the rotor assembly, whereby the outer shell is often not a perfect cylindric shell.
The contactless dosing with the perfecdos PDos X1 jet dispensing valve offers decisive advantages here.
