Abstract: Inverter|fed three|pole AMB was studied. A linear analytical model considering the air gap eccentricity was presented. Its accuracy was verified by the simulation results of Maxwell 2D based on finite element analysis. Based on the simulator coupling technology, the inverter|fed three|pole AMB control system with displacement control in the outer loop and hysteresis current control in the inner loop was proposed. The simulation results of software SIMPLORER verify the performance of the control system.
Key words: active magnetic bearing; inverter; three|pole; hysteresis current control
