Register NowAn electric motor manufacturer faces demanding market requirements for increased product durability, greater motor efficiency and lower production costs. We offer reliable and cost-effective solutions for helping electric motor manufacturers to improve performance and reduce overall costs.
Shaft Mountings
Challenge 1: Bearing loosening
Frictional methods such as press and shrink fits and mechanical methods such as splines, keys, and locking pins don't provide a 100% metal to metal contact between bearings and shafts. This leads to wallowing and backlash.
Solution: Retain bearings on shaft securely with LOCTITE 641 or LOCTITE 609
Challenge 2: Shaft fracturing
Mounting rotor onto the shaft using frictional methods doesn't provide a 100% metal to metal contact and results in fractures due to stress concentration when subjected to high dynamic loads.
Solution: Retain rotors on shaft with LOCTITE 638 or LOCTITE 648
Housing and end plates
Challenge 1: Housing end bell loosening
Bolts with lock washers loosen from vibrations of the cooling equipment's operation. When end bells loosen the motor's integrity gets compromised.
Solution: LOCTITE 243 fills voids between threads to prevent movement that leads to fastener loosening.
Challenge 2: Sealing of motor housing
Perfect sealing of end plate to housing, cover to junction box or housing to junction box to protect against chemicals and moisture is extremely important. Pre-cut gaskets don't fully conform to flange surfaces and lead to leaks.
Solution: For perfect gasket sealing, apply LOCTITE 5910 or 518 on flange surfaces.
Magnet Bonding
Challenge 1: Long production cycles
Bonding magnets with epoxy combined with an oven-curing process, is a time consuming method. A faster curing adhesive is needed to reduce motor assembly time and increase the production line output.
Solution: LOCTITE 326 and LOCTITE 7387 Activator reduce adhesive fixture time from 1 hour to just 1 minute.
Challenge 1: Chipping of magnets
Messy clip attachment methods sometimes chip the magnets leaving loose material in the motor housing. A fast curing, high strength, magnet bonding adhesive is necessary.
Solution: LOCTITE 324 and LOCTITE 7075 activator eliminates epoxy mixing and material waste.
Motor stator windings – Potting
Challenge 1: Long production cycle
Solvent and moisture ingress can cause mechanical damage and degradation to critical components due to thermal cycling, vibration and impact. Traditional potting methods are generally time consuming.
Solution: Encapsulate critical components and seal aperture with LOCTITE EA E-30CL potting solution.
Wire tacking of electrical connections
Challenge 1: Coil adjustment
Reinforce wires to prevent breakage during production and prevent any short circuits during the winding operation.
Solution: Use LOCTITE 401 Cyanoacrylate
An Generator manufacturer faces demanding market requirements for increased product durability, greater electrical efficiency and lower production costs. We offer reliable and cost-effective solutions for helping generator manufacturers to improve performance and reduce overall costs.
Panel Assembly
Challenge 1: Temperature and corrosion resistance
Circuit boards within the generator housing need to be protected from the outside environment. Therefore the sealing method needs withstand varying weather extremes and must not cause corrosion to electronic components.
Solution: Seal with LOCTITE 5900 and withstand temperature ranges of -65F to +500F
Stiffner bonding
Challenge 1: Rust prevention and cost reduction
Conventional methods like welding require a higher sheet thickness. This results in an increase in weight and and consequently cost. Welding also leaves micro porosities leading to rust in the long term.
Solution: Bond securely with LOCTITE MS 9360

Solution: LOCTITE 243 fills voids between threads to prevent movement that leads to fastener loosening.
Challenge 2: Noise and vibration reduction
Generators need to be designed in a way to limit the amount of noise and vibration that they generate.
Solution: Terophon 112DB helps in reducing both noise and vibration
Challenge 2: Sealing of motor housing
Perfect sealing of end plate to housing, cover to junction box or housing to junction box to protect against chemicals and moisture is extremely important. Pre-cut gaskets don't fully conform to flange surfaces and lead to leaks.
