Reducing the weight of industrial rotational machinery equipped with Active Magnetic Bearings (AMBs) has been shown to accomplish efficient hydraulic performance and a high-speed rotation for improving space efficiency and cost reduction. One of our solutions for increasing rotational speed is to experimentally demonstrate passing of the 3rd bending critical speed. In this paper, a flexible rotor supported by AMBs is introduced. The controller design for mode separation control is studied and the stability margin is evaluated according to ISO 14839-3. After checking the stability, we successfully perform the rotation test to pass a total of 5 critical speeds, i.e., 2 rigid modes and 3 bending modes, by using modal balancing technique (5 correction planes and 1 vibration sensor). This paper proves that stability and balancing are key technologies to complete the high-speed rotation.
