A Magnetic Bearing Wheel (MBW) with inclined magnetic poles is under development. This paper deals with the low disturbance control method of MBW based on the disturbance feedback. This control method generates the rotor displacement command that converges synchronous and harmonic components included in the disturbance of MBW to zero. This control system can be stabilized by adding appropriate phase lead as a function of the rotational speed of the rotor to the rotor displacement command. Based on the stability analysis by root loci, a simple adjusting method of the phase lead parameters is proposed. Next, the effectiveness of this control method is verified by the numerical simulation and the experiment. This control system enables the disturbance of MBW to decrease to 0.1 N_<rms>/0.045 Nm_<rms> or less in all rotational speeds up to 6000 rpm.
