摘要:
A stabilization system for a rotating load, such as a flywheel, includes a mechanical bearing to continuously support a shaft of the rotating load so as to hold the shaft at a substantially fixed axis of rotation. A magnetic stabilization assembly includes a plurality of electromagnets arranged around the shaft. Control circuitry for controls a resultant magnetic field generated by the electromagnets such that the magnetic field acts on a ferromagnetic element of the shaft to reduce imbalance forces acting on the shaft.

A machine is on a first side of a plate (20) and a rod (50) passes along or through the plate (20). The plate (20) is susceptible to vibrations arising from operation of the machine. An active vibration suppressor (60) is mounted on the rod (50), and a controller is configured to control the active vibration suppressor (60) to suppress vibrations of the plate (20).

A system, method, and apparatus for damping vibration in a rotor 12 supported by primary bearings 14, 16 are provided. The system includes a magnetic coupling 104 configured to magnetically engage a rotor 12 supported by one or more primary bearings 14, 16, and a piston 108 coupled to the magnetic coupling 104. The system also includes a damper 102 engaging the piston 108 and configured to damp the rotor 12, wherein the damper 102 is substantially non-load bearing.

摘要:
A damping apparatus is disclosed including at least one pair of magnets, a conducting member, a magnetic shunt, and a temperature sensing mechanism. The pair of magnets defines a gap therebetween. The magnets generate a magnetic flux circuit having a magnetic flux path within the gap and a magnetic flux return path outside the gap. The conducting member is positioned at least partially within the gap. The magnetic shunt is positioned at least partially within the magnetic flux return path of the magnets. The temperature sensing mechanism is coupled to the magnetic shunt. The temperature sensing mechanism is configured to control a position of the magnetic shunt based on a sensed temperature.
