Abstract :
A new energy efficient magnetic bearing is developed. The magnetic forces to current inputs relation for the new bearing is analyzed with both 1-D magnetic circuit and 3-D magnetic field modeling. The test rig for the new magnetic bearing is constructed. A digital controller for stable levitation of rotor-magnetic bearing system is implemented on a dSPACE controller. Energy efficient magnetic bearings may find great use in some applications such as flywheel energy storage systems.
