Abstract

The magnetic gear with Halbach Permanent-Magnet array can offer higher on transmitted torque compare to radially magnetized permanent magnet and also capable of increasing the magnetic field. Then, the study of this paper focuses on the effects of critical design parameters on the transmitted torque. Furthermore, the magnetic field and the steady-state torque characteristic of Halbach type computed by commercial software ANSYS/Maxwell. Under the use of Taguchi method, determined parameters in four levels, and focused on five factors comprise the length of outer and inner rotor iron part, the length of outer and inner rotor permanent magnet, and the length of pole pieces. Analysis result shows the optimum condition, the percentage contribution of the design parameter using the ANOVA test, and the prediction torque was also obtained. Finally, this paper shows the contribution of the outer and inner rotor permanent magnet with 0.35% and 15.53%. The radial length of the pole pieces contributed 3.21%. While the percentage of the outer rotor iron part is 77.18%, and the inner rotor iron part does not significantly affect to the steady-state torque, then it pooled. The estimated torque at optimum condition is 2179.55 Nm
