3 Retaining Gasketing Threadlocking Threadsealing Potting Wire reinforcement / Electrical connections General Magnet Coatings & Cleaners Retaining AC Bearings to housing Achieve handling Strength after 3-80 min. (depending on selected Product please see Products Selector) Increase mechanical strength even with dynamic loads Prevent fretting corrosion Reduce design costs by replacing mechanical fasteners and/or interference fits to reduce design costs Reduce number of components / tolerance Increase bearing life 1. DC Gasketing End plate to housing Cover to junction box Housing to junction box Eliminate pre-formed gaskets (no need to keep stock of different gasket types) Solution for flameproof electro-motors where rubber gaskets are not allowed Fill surface defects Reach high IP rating Avoid gasket relaxation Increase reliability & product life Minimise use of o -rings 2. 3

4 Retaining Gasketing Threadlocking Threadsealing Potting Wire reinforcement / Electrical connections General Magnet Coatings & Cleaners Threadlocking Assembly screws Lock parts against vibrations Reach thermal cycling resistance Seal against liquids and gases Prevent corrosion Replace traditional mechanical locking devices for fewer parts and reduced costs Improve / preserve clamp load Improve reliability / life expectancy 3. Through bolts Threadsealing Threaded fittings 4. Seal against humidity Seal against industrial liquids & gases Prevent corrosion Achieve vibration resistant sealing Replace seals & o -rings Improve reliability / life expectancy Junction box plugs Innovative Solutions for Electric Motors 4

5 Retaining Gasketing Threadlocking Threadsealing Potting Wire reinforcement / Electrical connections General Magnet Coatings & Cleaners Potting Encapsulate & insulate from environmental effects Protect components against impact, vibrations, thermal shocks & dust Prevent contamination & corrosion Improve heat dissipation Simplify process automation Improve reliability / life expectancy 5. Seal wire connectors Wire Reinforcement / Electrical Connections AC DC Lead wire bonding Unitise wires & electrical connections Improve resistance to high loads such as centrifugal forces Protect wires from flexing fatigue Achieve higher rotation speeds Improve reliability / life expectancy 6. Reinforcing wire on stators Reinforcing wires at commutator connection 5

6 Retaining Gasketing Threadlocking Threadsealing Potting Wire reinforcement / Electrical connections General Magnet Coatings & Cleaners AC Position wires & insulation during manufacturing Prevent wire breakages due to vibration 7. Lead wire tacking on stators and insulation to stator wires DC Insulation to rotor General Bracket to housing Bond support frame Join and seal dissimilar materials, enabling use of new, improved & innovative materials Simplify design, reduce number of used parts Fill gaps, allowing wider tolerances Improve vibration resistance & reduce noise Reduce costs 8. Stator to housing Innovative Solutions for Electric Motors 6

7 Retaining Gasketing Threadlocking Threadsealing Potting Wire reinforcement / Electrical connections General Magnet Coatings & Cleaners Magnet AC DC Ring magnets to rotor Magnet segments to rotor 9. Replace traditional mechanical fixing methods to reduce number of parts / costs Fill gaps (eg. between stator and magnet and rotor to magnet) for lower tolerances Improve resistance to impact / vibration Improve adhesion to all magnetic materials Simplify automated assembly Reduce vibration & noise Improve high temperature resistance Coatings & Cleaners 10. Dramatically enhance coating adhesion Reduce the rate of surface corrosion when paint is compromised Increase user safety & enviromental friendliness of your processes Reduce costs 7
