Magnetic Bearings
Featured Product from Douglas Electrical Components
Industrial magnetic bearings achieve their highest operating efficiency when contained within strict vacuum or pressurized gas environments. To maintain these sensitive internal conditions, electrical, control, and monitoring signals must pass in and out of the housing without creating leak pathways. Douglas Electrical Components solves this challenge with high-performance magnetic bearing electrical feedthroughs, hermetic wire feedthroughs, and sealed cable harnesses.
By leveraging advanced epoxy technology, these solutions provide an absolute hermetic seal that confines liquids and gases to their intended environments while offering engineers total design flexibility.
Unmatched Technical Design Versatility
Magnetic bearing systems vary wildly from compact test setups to heavy industrial machinery. Douglas's epoxy-based designs accommodate various application scales, providing customization across multiple design components:
- Footprint Variety: Scaling from basic circuit-board-level connections up to heavy-duty, high-power cables.
- Production Flexibility: Supporting low-volume test and measurement projects up to full original equipment manufacturer (OEM) production lines.
- Component Integration: Customizing the outer housing, base materials, and connector configurations to drop seamlessly into existing machinery.
Key Technical Advantages
- Direct Shielded Sealing: Conductors and shielded cables seal directly into any vacuum flange. This direct interface drastically reduces electrical noise and increases signal integrity.
- Optical Integration: Fiber optic cables can be hermetically sealed to a wide range of standard and custom flanges.
- Advanced Dual-Seal Layouts: Combines proprietary DuctorSeal® wire/cable feedthroughs for high-vacuum sealing with JacketSeal™ technology to prevent downstream transfer fluid leaks in high-energy applications.
- Portplate Assemblies: Combines multiple high-power and signal feedthroughs into a single integrated portplate. This eliminates independent connection points, reduces potential leak paths, and saves spatial footprint.
Critical Application Environments
These robust hermetic solutions are engineered specifically for high-stress applications that rely heavily on magnetic bearing efficiency, including:
- Industrial Turbines
- High-Speed Compressors
- Energy-Storage Flywheels
