Project Summary

This Final year project deals with the design and analysis of Thrust Active Magnetic Bearings that can generate and regulate forces up to 5N but for the safety factor, AMB will be able to generate forces up to 8N. By using the analytical calculations different design parameters were obtained for the electromagnet that can generate forces up to 8 N on the thrust disc. Electromagnets will levitate the rotor in vertical position.

• Control Design & Implementation

• Experimentation

• Tuning of Designed Controller

• Final Report

Benefits of the Project

This project deals strictly with thrust Active Magnetic bearings, the design of the bearing, deployment of sensors, and control mechanisms will all be developed for precise axial control of a thrust disc that is rigidly attached to the rotor, hence by controlling the thrust disc we tend to control the axial motion of the rotor. The scope is also limited to small forces of range 1 to 10 newton. The nominal air gap between the thrust disc and magnet is approximately 3mm. The expected outcome of our project is a prototype thrust active magnetic bearing test rig.

Technical Details of Final Deliverable

The aim is to build an active magnetic bearing we selected the ferromagnetic materials. This would allow to include a control system, as by changing current in the coils force can be varied and maintaining equilibrium. The basic working principle is to nullify the external force by the force induced by the magnet on the shaft. By the placement of a sensor and microcontroller, a feedback loop can be included. The sensor will monitor the position of the shaft and send a signal to the microcontroller. The microcontroller would then send the signal to the power amplifier which produces the current necessary for the magnet to generate force.
