抄録

In this paper we propose an unbalance compensation method, which is able to work through a wide range of rotational speed. Actually the vibrations due to unbalance or eccentricity on the rotor contain the direct synchronous rotational speed signal. It is not reasonable using an extra rotational sensor to measure the rotational speed. Thus a resolver-like evaluation of rotational speed is proposed to serve as the necessary synchronous rotational speed signal. The speed of rotation is directly evaluated from the unbalance driven compensation signal. The unbalance compensation without using a rotational sensor are realized successfully on a test rig with 25 kg-rotor from 0 to 28000 rpm. Moreover, a speed control using the evaluated speed signal is also implemented.
