Active Magnetic Bearing as a Force Measurement System

Prince Owusu-Ansah, Hu Yefa, and Rhoda Afriyie Mensah
Abstract—This article presents active magnetic bearing as a force measurement system. Identification of the dynamic behavior of the rotating machinery have been studied. The main technique was to excite the system under consideration in a time, frequency domain using MATLAB program which runs on a personal computer. Experimental results of the free-free rotor model for the first three elastic mode shapes is presented. The rotor was excited with stepped sine excitation from 20 to 800Hz, with the sinusoidal excitation exciting the rotor at each bearing ends. The frequency response function at AMB1 which demonstrated the growth of gyroscopic effect was measured at four different speeds (0, 2000, 4000, 6000 1/min). The gyroscopic split was obvious at a speed of 53.2Hz for the first Eigen frequency at a speed of 60001/min. Calculated eigen frequencies values which was measured showed small difference between them which goes to confirm the suitability of AMBs as a force measurement system.

Index Terms—Force measurement, natural frequency, rotor, identification.
