Summary:Current industries that use high-speed rotation systems are starting to replace the standard mechanical bearing systems with magnetic suspension systems. This tendency to replace mechanical bearings is due to the advantages of magnetic bearings, for instance low losses, high reliability lubrication free operation and the ability to work in vacuum Magnetic bearings can allow the suspension of a rotor without any mechanical contact in rotating machinery which can produce a high rotating speed and position precision, thus removing the problems introduced by mechanical bearings such as low dynamic stability, thermal lock, and limited rotation speed This paper deals with design procedures for two different topologies of active magnetic bearings (AMBs) that might be applied for a high-speed machinery. The virtual prototypes of the magnetic bearings are created and simulated, and a comparative analysis of magnetic bearings is performed.
