Electric Motors
Adhesives & Sealants in Electric Motor Assembly
- Sealing suitable motor housings, covers and flange interfaces
- Bonding suitable rigid metal motor components and assembly interfaces
- Securing suitable motor housing, mounting and heavy-duty threaded fasteners
- Protecting selected interfaces from moisture, dust and environmental exposure
Bonding, Sealing & Threadlocking for Electric Motors
Electric motors operate through continuous rotation and may be exposed to vibration, thermal cycling, moisture and demanding mechanical conditions. Adhesive technologies can support specific motor assembly interfaces where bonding, sealing or threadlocking is required.
Fasto solutions can be evaluated for motor housing and flange sealing, rigid metal component bonding, motor and mounting fasteners, selected component interfaces and environmental sealing applications.
The appropriate product should be selected according to the actual substrate, joint geometry, load, temperature, vibration, environmental exposure and manufacturing process.
- Resistance to vibration and mechanical movement
- Thermal cycling and operating-temperature compatibility
- Moisture, dust and environmental sealing
- Reliable bonding of suitable rigid metal components
- Secure fastening of suitable threaded assemblies
- Compatibility with the intended manufacturing process
