SIMOTICS Active Magnetic Bearing Technology

Using intelligent correlation technology, energy efficiency is significantly improved, and integrated operation and maintenance solutions maximize plant availability. SIMOTICS active magnetic bearing technology uses non-contact bearing technology to achieve the trend of using active magnetic bearings for high-speed large-scale machines.

Active magnetic bearing

Suspended in a magnetic field

The use of a suspension shaft greatly improves efficiency: using SIMOTICS active magnetic bearing technology, the controlled magnetic field can keep the rotor in the center position. This indicates that compared to traditional bearings, there is no friction and therefore no wear occurs. Non contact suspension also indicates that no oil is required to eliminate the risk of oil leakage: it is also an ideal choice for applications that must comply with environmental regulations or need to prevent process pollution.

High accuracy - achieving excellent operation

The module for precise control of shaft suspension status automatically provides comprehensive status data on a standard Siemens interface for system monitoring, preventive maintenance concepts, remote diagnosis, and remote control. The sensor captures the shaft position 16000 times per second. The controller can use this information to adjust the magnetic field, and even at maximum speed, a few tons of rotor can remain in the position window of the human hair diameter.

"Because the controller actively suppresses rotor vibration, in high-speed, high-performance applications, the shaft can continuously operate at all speeds between static and maximum speed, and there is no speed gap at the rotor resonance frequency attachment, just like machines using traditional bearing technology.".
