Radial Bearings

The radial magnetic bearing positions the rotor using four electromagnets, each comprised of a stator component and rotor component. The stator component is bolted to the machine housing while the rotor component is a sleeve fitted to the shaft.

Opposite electromagnets are adjusted to pull against one another. When an external force causes the rotor to change position, the movement is identified by position sensors. The electronic control system responds by adjusting the current flowing through the respective electromagnets – returning the rotor to its original position.

 

 

 

 

Watch as the magnetic bearings levitate the rotor.
