axial bearing
2 radial bearing axes for x- and y-direction
1 axial bearing axis for z-direction
Advantages
• Contact-free levitation - high rotational speed
• Active damping - continuous speed range
• Oil free - for environmentally sensitive areas
• Resistant to wear - less maintenance
• Frictionless - energy efficiency
• No gearbox needed - reduced foot-print
• Digitalization - condition monitoring

SIMOTICS AMB-Technology automatically supplies valuable service-relevant operating data
Rotor Speed [rpm]
Time [s]
Control Current [A]
Rotor Position [µm]
Run-up of a Rotor in AMB• Rotor position
(16.000 measurements per second)
• Bearing force (control current)
• Dynamic load (control voltage)
• Operating temperatures of the bearings
Even small variations in the driver, the working machine and process are detectable
Supports online remote monitoring, data-based service concepts and process optimization
Simple integration into Siemens condition monitoring concepts
