Analysis of a Single Actuator Double Winding Active Magnetic Bearing (AMB) Using Ansys Maxwell Simulation Software

This paper describes the analysis and simulation of an electromechanical hovered system which has a coil wounded in the two legs of the actuator and a circular rotor. For a successful design of Active Magnetic Bearing(AMB) system, proper design of actuator is obligatory which controlled all the lifting and hovering force of the process. The magnetic properties of the system fully rely on the coil turns and the actuating current density in the winding. To decide the actuator for the proposed work, magnetic properties are necessary to analyze. In this probed work, inductance for different airgap is analyzed. Magnetic properties such as flux, flux density, magnetic force and field intensity for different airgap between the rotor and actuator are analyzed using ANSYS software base simulating environment. Performance of the magnetic properties with the change in a number of coils turns on the actuator and different current density are investigated for different airgap between the actuator(stator) and the ball rotor.
