Application of low viscosity resin masses
Continuous, pulsation-free dispensing flow in the production of electric motors
(PresseBox) - In the production of electric motors - more precisely in the casting of the coil in the stator - very liquid, low-viscosity materials are processed. A continuous pulsation-free dispensing flow of the material is particularly important here.
By trickling or impregnating the rotating drive components, the coils are provided with a protective layer. This process later improves the performance of the motors and generally extends their service life. After curing, the applied resin becomes a hard-elastic moulding material. It retains its good mechanical and electrical properties even at high temperatures. It insulates, prevents vibrations and the coils become more robust.
In order for the resin masses to harden, they - and also the stators - must be heated. This requires perfect process reliability. The components are either charged with electricity (electricity heat / induction) or heated in special industrial furnaces (circulating air heat) in so-called impregnation machines or trickle systems. The aim is a perfect trickle result and a precise flow of the resins between the windings of the coil.
ViscoTec dispensing systems are excellently suited for the application of resin masses. They can easily be integrated into existing production lines. However, they are also impressive in newly designed customer-specific systems.
The endless piston principle used in the ViscoTec dispensing pumps enables pulsation-free, continuous dispensing. Continuously adjustable in application quantity and application speed. Therefore, the dispensing technology specialist can guarantee an ideal penetration behaviour and a completely clean impregnation result, both when processing 1- and 2-component resin masses or trickle resins. ViscoTec dispensing pumps function regardless of viscosity. Even if viscosity fluctuations occur due to storage time or storage temperature, the dispensing functions perfectly. Dispensing is carried out from a dispensing tip with hose. A hardening of the pump is conceptually prevented.
The dispensing pumps are combined with the ViscoTec treating systems ViscoTreat-R or ViscoTreat-Inline. Thanks to optional vacuum suction, they ensure a completely air-free supply to the 1- and 2-component dispensers. The operator has no contact with the material.
Trickling is impressive in many respects: Precise dispensing results in specific material consumption per component. This ensures optimum impregnation. Constant and automatic processes are created. In addition, the resin is perfectly distributed on the coils. This in turn means reliable electrical insulation and improved thermal conductivity.
The proven technology in ViscoTec products ensures the highest quality and maximum production output.
