Integrated Diagnostics of the Rotating System with an Active Magnetic Bearing

Abstract

Nowadays rotating systems are equipped with diagnostic systems that are based on collecting and recording measurement data and that process a huge amount of data during the machine operation. An analysis of these data and their interpretation, as well as finding a correlation between process parameters and dynamics of the machine is a very important problem. In the paper, a concept of the integrated diagnostics of the rotating system with an active magnetic bearing is presented.

Monitoring and diagnostics of special-purpose turbomachines

“…It is driven by an electric motor, controlled by an inverter and connected to the shaft by a exible coupling membrane. The mass of the rotating system is 4.85 kg and the length of the shaft -1923 mm [8][9][10].…”

“…The diagnostic system was designed to analyze and interpret the measurement data collected during the operation of the rotating machine system with magnetic bearings. The source of the measured signals for the database of the diagnostic system are sensors installed in the magnetic bearing, which are a necessary part of the modules to control the operation of the bearing [8].…”

Theoretical and Experimental Investigations of Dynamics of the Flexible Rotor with an Additional Active Magnetic Bearing

“…To achieve these goals, AMB systems have to be optimised in an overall mechatronics design approach. This leads to a new concept for control systems and actuators [11][12][13][14].…”

“…Independent auxiliary procedures that allow for experimental testing the actuator paths of the bearing have been developed. These procedures form a program for operation of the measurement-control card, which is the main element of the bearing digital control system [11].…”

“…The application of magnetic bearings as a system of shaft suspensions gives supplementary, unparalleled in classical solutions, diagnostic capabilities [10][11][12][13][14]. There are, however, also high requirements concerning the control system of the shaft position.…”
