“…The magnetic bearings was the most typical application of magnetic force. These bearings included magnetic suspension in artificial heart pump [3][4][5][6], flywheel energy storage [7][8][9], bearing less drivers [10,11],electrobemagnetic exciter [11][12][13][14][15][16][17]and bearings using in special turbo pumps [18,19].The structure designing, magnetic force analysis, contrller and application of magnetic bearings were studied in the references mentioned above. There study regarded magnetic devices as afunctional unit and studied from the structure and the force characteristics all in all.…”

An idea of controlling or restricting axial movement of the rotor system using magnetic force was proposed in this paper. A device named Magnetic Balancing Disc(MBD) was developed which could play a role better than general fluid balance disc in certain compressor. Basis principle of magnetic balancing disc was introduced including basic structure of physical integration and feasibility of balancing point. Discussion of functional integration principle based on the design point of view was presented including three design patterns of rotor system, mathematical expressions for design and graphic method. Feasible region analysis based on the balancing point was proposed including working point design under ideal conditions and feasible region assessment under service state.

“…At the critical rotating speed, the amplitude of the rotor vibration increases suddenly [Inoue & Hikihara, 1998;Lawen & Flowers, 1996]. The flywheel rotor also shows the increase of the amplitude of the whirling motion at the critical rotating speed [Hikihara et al, 1997;Higasa, et al, 1993;Hull, 1997;Takahara et al, 1995Takahara et al, , 1997. Moreover, it has been reported that the flywheel rotor levitated by the magnetic bearing has four natural frequencies for the fundamental mode [Hikihara, 1995].…”

This paper presents the discussion of experimental results and numerical simulation of nonlinear phenomena in a flexible rotor system under mechanical resonance. The whirling motion of the first flexural mode of the rotor causes the hunting of its rotating speed. Hysteretic jump phenomena exist between the charge and the discharge of the rotation. It is shown that the quasi-periodicity of the whirling motion is closely related to the hunting of the rotating speed. When the rotor is coupled to a generator, a continuous change of output power cannot be achieved under mechanical resonance. These results show the necessity to stabilize the whirling motion and the hunting, for example in a flywheel energy storage system. *
