Magnetic bearing Foster Miller Inc

We specialize in the research & development of active and passive magnetic bearings and suspension systems. We can adapt our proven proprietary designs or research & develop new magnetic bearings tailored for your application.

Passive magnetic bearings use opposed pairs of permanent magnets on the rotor and stator to establish the bearing%u2019s stiffness. Inherently simple, these bearings do not require any shaft position sensors or an electronic controller for operation.

Active magnetic bearings offer higher load-carrying capability and can accommodate higher temperatures. Their electronic controllers tune bearing stiffness and damping properties "on the fly," allowing for adjustments to system dynamics that affect resonant frequencies and reduce transmitted vibration. Our proprietary virtual balancing method adjusts the shaft%u2019s running position to minimize vibration.
