This Active Magnetic Bearings (AMB) Mechanical Final Year Project is about magnetic bearing which is a bearing that is based on the load with the help of magnetic levitation. Magnetic bearings also make the machinery to move without physical contact. These bearings lift up the rotating shaft and allow the motion without friction. The constant equilibrium is obtained with one or more control loops with the active magnetic bearings (AMB).
The general machinery system is consists of A/D and D/A conversion, sensor, and power amplifier. The distance of sensor with its axes is discovered with location of sensors and changed into standard voltage signals. The error signal is caused in the controller on comparing the values. The controller operates the digital signal after converting A/D and it is based on control arithmetic to produce current setting signals.
On D/A conversion, the current signal operates the power amplifier which keeps the value of current in the electric magnet winding with the help of controller. Hence the control system alters the electromagnet current to manipulate attraction force and to balance the location.
AMB and its monitoring system provide bearing forces and rotor displacements. This results online monitoring of process parameters and discover faults like increased reliability. AMB controls the action of machine. Hence the action is maintained and increased based on process manipulations. The system monitors the resonance frequencies of the rotor.
Hence the conclusion is that the control loop of the AMB creates the space among the shaft and bearing with passive AMB. They are applied in industries like petroleum refining, electric power generation, natural gas pipelines, and machine tool operation.
