Whereas the main objective is to keep the shaft centred within the bearings, the setup of a magnetic bearing system also allows for controlled movements of the shaft.
MECOS offers a wide range of advanced control schemes to deal with the requirements of different applications, such as:
- unbalance force rejection control (UFRC) for vibration free operation
- controllers for highly gyroscopic rotors
- controllers for supercritical rotors allowing safe crossing of bending critical speeds
- built-in frequency response measurement and data acquisition function for system identification, control performance assessment and preventive monitoring
The magnetic bearing system has its built-in supervision monitoring watches not only AMB internal states but also external load conditions of the machine such as speed, displacements, unbalance etc. The measured values can be accessed based on CAN-Interface and CANOpen protocol.
