Abstract

The invention discloses a magnetic suspension bearing system and its control method and device. The control method of the magnetic suspension bearing system comprises detecting an initial position of a middle axle of the magnetic suspension bearing system, detecting the central position of a protection bearing in the magnetic suspension bearing system, acquiring preset amplitude and preset frequency, calculating a middle suspension position in shaft floating according to the initial position, the central position, the preset amplitude and the preset frequency, and controlling a current passing through a bearing coil in the magnetic suspension bearing system by the middle suspension position as a control object. The method and device solve the problem that a protection bearing of the existing magnetic suspension bearing system is damaged easily, improve magnetic suspension bearing system reliability, prevent damage to the system and reduce a maintenance cost.

Description

technical field [0001] The invention relates to the field of magnetic suspension, in particular to a magnetic suspension bearing system and a control method and device thereof. Background technique [0002] For the pure electromagnetic magnetic suspension bearing system, before the system is powered on, the shaft stops at the bottom of the protective bearing. If the direct floating shaft is used, the shaft will quickly move from the bottom of the protective bearing to the center position, and the floating shaft will instantly move to the center position. There will be a relatively large current, and in serious cases, there may be a problem with the shaft collision protection bearing. It is easier to shatter the protection bearing, resulting in damage to the protection bearing, which has a greater impact on system reliability. [0003] Aiming at the problem that the protective bearing of the magnetic suspension bearing system is easily damaged in the related art, no effective...
