Magnetic gears have the advantage of low noise compared to mechanical gears because there is no contact between solid materials. However, magnetic gear has the disadvantage of having a lower torque density than mechanical gear. For this reason, the study of efforts to increase torque density is an interesting topic for research. In this research, how to produce a larger torque at a constant magnetic volume by varying the number of poles and reducing the thickness of the magnet at a constant magnetic volume. In addition, the air gap is also varied, which corresponds to the tolerance in the manufacture of high-speed gear and low-speed gear on the internal magnetic gear. The research was conducted using 3D modeling and experiments. As a result of this research, it is known that the addition of the number of poles 2 to 4 poles on high-speed gear and 4 to 8 poles on low-speed gear with total volume magnet constant, will increase the maximum static torque value of 15.9% and 43%, respectively. Besides that, the air gap reduction with an interval of 0.2 mm will cause an increase in the maximum static torque value of 3.8% to 5.3%. A comparison between numerical and experimental results is also discussed in this study.
