The bearing does not shutdown in this situation but will continue to produce its maximum rated load (i.e., it will "load share" with auxiliary bearing). Once the transient load is removed, the bearing controller will automatically regain control of the shaft and center it within the magnetic ball bearings .

The thrust magnetic bearing is comprised of a rotating thrust disk mounted between two stationary thrust magnets.This is dependent on bearing size and shaft diameter but, as a reference, the 400 lb load capacity Fusion® radial magnetic bearing (which includes integrated control electronics) weighs approximately 25 lbs per bearing.Synchrony has supplied magnetic bearings with a radial load capacity ranging from 35 lb to 3,200 lb.

Magnetic bearing size is dependent on load capacity and shaft diameter. As an example, our 400 lb load capacity Fusion® radial bearings have an axial length of 3.8 in and diameter of 7.0 in.Yes, our magnetic bearings provide sufficient damping such that amplification factors at critical speeds are typically less than 3. Using adaptive control techniques for synchronous suppression of vibration and force, it is possible to greatly attenuate or eliminate the amplification of vibration at critical speeds.

During normal operation, the magnetic bearings levitate the shaft in space eliminating mechanical friction. Therefore, the main factor in limiting speed is strength of materials of rotor components. For our standard radial bearing, the rotor surface speed is limited to about 590 ft/s (180 m/s).Synchrony recommends that a UPS be used to supply power to the magnetic fag bearings in the event of an unexpected loss in power (we offer power supplies with battery backup).

This is dependent on bearing size, but as a reference, our 400 lb load capacity Fusion® radial magnetic bearing requires a maximum of 100 W at 48 VDC per bearing.Yes, our magnetic bearing systems utilize both radial and thrust auxiliary bearings. The gap between the rotor and the auxiliary bearing is smaller than the gap between the magnetic bearing rotor and stator and motor rotor and stator. The purpose of the auxiliary bearing is to protect these components in the event of power loss or large transient load.

The radial magnetic bearing is constructed in a similar manner to an electric motor. They are comprised of a multi-pole laminated stator, magnet wire coils and laminated rotor.Plastic ball bearings become completely non magnetic when fitted with either polymer, glass, or non magnetic 316 stainless balls. They are ideal for use where there can be no magnetic distortion.

Scientists have discovered how to make super strong magnets — stronger than any magnets we’ve seen to date — fit into tiny metal beads. These are sometimes called “rare earth magnets” or “builder balls”, and they are very popular. They are the same size as timken bearings (bb’s, like in a bb gun). The magnetic balls are almost like clay in how they form shapes, and they are even more fun because they stick to each other even if there is skin in between them. That means the magnetic balls can be used in pairs to look like fake earrings, fake nose rings, and fake tongue rings, too.
