Applications

Magnetic bearings operate most efficiently in vacuum or pressurized gas environments. Our magnetic bearing electrical feedthroughs, hermetic wire feedthroughs, and hermetic cable harnesses and seals allow power, control, and monitoring signals to flow in and out of magnetic bearings while maintaining this critical internal environment.  Using epoxy to create the hermetic seal ensures liquids and gases are contained to the environment that is expected.  Our design flexibility allows for customization of various elements including the housing, cables, materials, and connector integration.  Magnetic bearing electrical feedthroughs are possible at a basic circuit board level as well as high power cables and feedthroughs and in various production volumes, from test and measurement to full OEM volume.

Features

TECHNICAL ADVANTAGES
  • Shielded conductors sealed directly to any vacuum flange
  • Fiber optic cables hermetically sealed to a wide range of flanges
  • Advanced dual-seal designs combine DuctorSeal® wire and cable feedthroughs for hermetic vacuum sealing of flywheel power and JacketSeal™ to prevent transfer fluid leaks.
  • Direct sealing of shielded conductors reduces noise and increases signal integrity.
  • Portplate assemblies combining multiple feedthroughs for power and/or signal into a single design, reducing potential leak paths and saving time and space
EXAMPLE APPLICATIONS
  • Turbines
  • Compressors
  • Flywheels
