In order to develop more precise inertial sensors such as floated gyros and accelerometers which will be used in inertial navigation system, a passive magnetic suspension system with an eight-pole stator, which can be applied to supporting the output axes of these sensors, is experimentally studied. Formerly in our previous report6), a theoretical analysis of the magnetic suspension system was described. This study is precise measurement of magnetic suspension forces related to displacement of the output axis by means of the experimental models of the magnetic suspension system mounted on the testing equipment which is produced for this experiment. These experimental models are designed according to the analytical results which were given by authors in the previous report, and the size of the models is determined so that the models could be applied to actual inertial sensors. The measured magnetic suspension stiffness of the experimental models is about 10 grw/μm, and the value is large enough to support the outut axes of the inertial sensors. And then it is shown that the experimental results of the magnetic suspension forces are in close accordance with the analytical results within a small displacement of the output axis. Furthermore it is shown that the experimentally obtained unstable regions of the magnetic suspension forces are narrower than those obtained analytically. Thus the result of the experimental study can be applied to design the magnetic suspension system.
