The axial forces' effect on the rotating shaft's performance is often harmful. So, this work is proposed to reduce their impact by using active thrust magnetic bearing for the Gas Turbine Model (ME9001) used in the power plant of south Baghdad station. The sub-optimal design was studied in this research to identify the ideal bearing dimensions in the suggested application. The genetic algorithm (GA) optimization approach with multi-objectives is used as part of the design process. Some of the results that had been reached were the current optimum design of TAMB (thrust active magnetic bearing), a shaft clearance radius of 3mm, and the operating gap varies from 0.5mm to 0.8 mm with a thrust force of 400KN. The saturation flux density of the saturated pure iron is approximately 2.3 Tesla, and the best straight part is from 0 to 1.5 Tesla. It was noticed that the value of flux density in the stator after optimization is approximately (1.7) Tesla, which does not exceed the saturation limit for pure iron flux density, which proves the validity of the design. The current density of the TAMB coil after optimization is approximately (2 A/mm2), which does not exceed the saturation limit. That proves the design validity and reduces the power loss of the TAMB coil. Also, the thrust collar thickness (disk) can be smaller than the back wall thickness of the actuator because the flux density in the back wall will reduce after passing from the actuator to the thrust collar through an air gap, and that gives the advantage in minimizing the thrust collar weight as well.
