Electrodynamic Magnetic Bearing - Zero Friction Solutions

The bearing to the right is a two magnet-row inner rotor bearing of homopolar electrodynamic type

By adding extra magnet rows the characteristics can be changed towards better load capacity and stiffness. Adding an extra third row to bearing on the picture will double the load capacity and stiffness. A fourth magnet would provide yet another doubling of load- and stiffness characteristics.

As described in the movie on the front page the bearing repelling forces are increasing with increased displacement. The stiffness on the other hand remains constant and is thus independent of the displacement. This gives the bearing yet another benefit over traditional bearing since it enables a very simple rotordynamic calculation/simulation.


Magnetal unique inner rotor bearing is now available for sale to R&D-departments and universities

The dimensions are: ID: 15 mm (0.59"); OD: 42 mm (1.65"); Height: 17 mm (0.67")
