325 Suppression and Reduction of Harmonic Disturbance Forces for Precision Magnetic Bearings

抄録

In this paper we discuss a method of realizing high precision radial magnetic bearings that are capable of high-speed operation by the suppression and reduction of the harmonic disturbance forces generated by the induction motor that is used to drive the magnetic bearing. Experimental data shows that a rotational accuracy of 31.8nm (3σ) can be achieved at 5,400rpm for an experimental radial magnetic bearing in which the spindle has a diameter of 80mm and a mass of 3.29kg.
