ThreeBond 1359E - Electric motors also need adhesives

The TB1359E joins ThreeBond’s impressive array of adhesives, coating agents, impregnation agents, magnet locking agents, balance adjusting agents and sealants, all capable of enhancing motor performance and reliability. Indeed the 1359E is part of a trend which sees acrylics replacing epoxy (e.g. for bonding ferrite to rotor in stepping motors) and anaerobic adhesives bonding plastic magnets as well as metals.

The combination of anaerobic and heat curing employed with ThreeBond’s 1359E makes it universally applicable, particularly for the assembly and repair as well as for the industrial manufacturing of high-strength, elastic joints with large gaps. Polymeric curing is effected quickly, e.g. 10 minutes at 120°C, producing a flexible resin which provides good sealing and excellent resistance to adverse effects of heat, moisture and vibration.

Typical adhesive applications in electric motors include bonding of: bearings, shaft-to-rotor, magnet-to-rotor, wires-to-coil, triangular coils to former, thermal conductive components, as well as for balance adjustment, prevention of screws from loosening and protection of electronic parts. In particular, Hard Disc Drive motors employ zero outgassing adhesives for fixing of wires, bonding VCM magnets and cases, and for sealing connectors.

ThreeBond’s 1359E offers cost-saving advantages in bonding of many metals such as steel, aluminium, zinc and their alloys in comparison with many traditional fixing methodologies.
