Abstract
Because a new function of rolling moment control was added to the JAXA 60cm MSBS, control capability of the 6 components of magnetic force was examined. Adding pair magnets on both ends of a main magnet in a 5 DOF control model provides the model with rolling moment, which can be controlled by changing 4 side coil currents adequately. The magnitude of the moment was evaluated well with a proposed analytical expression. The effect of roll angle on the magnetic force except the rolling moment was estimated less than 0.5%FS in the tested range. The effect of rolling moment control current on the force was not changed with the roll angle. The reference balance was recalibrated to meet the calibration range to that of 5-axis calibration test of the JAXA 60cm MSBS. New error evaluation of Fx,Fy, and Fz gives 1.2%FS, 0.8%FS, and 1.2%FS, respectively.
