Title: Method of controlling magnetic bearing device
Inventor: ISHIDA KIYOSHI
IPC: F16C39/06
Filed: 1983-03-02
Abstract: PURPOSE:To ensure always stable operation by providing an impulse type disturbance to the force acting on the center of gravity and successively correcting the positional coefficient of the center of gravity. CONSTITUTION:When a weight 33 is attached to the right end of a rotary shaft 1, the center of gravity G is moved to a new center of gravity G deg. due to the attached weight. In this case, if the positional coefficients of the center of gravity l1s, l2s are left without being corrected, a torque may results which will shake the rotary shaft. To prevent this, merely the positional coefficient of the center of gravity l1s should be changed from l1 to l1 deg. and that l2s from l2 l2 deg. at the time when the weight 33 is attached. However, the shape and mass of the weight 33 being unspecified, it is extremely difficult to obtain the l1 deg., l2 deg.. Accordingly, disturbance is purposely provided to detect the deflection of the rotary shaft 1 in order to judge whether the previously determined l1s, l2s are proper or not and, if not proper, these are corrected. This procedure is repeated until the optimum values can be obtained.
