Document Type and Number:
WIPO Patent Application WO/2016/188461
Kind Code:
A1
Abstract:
A magnetic bearing control method, comprising the following: acquiring a suspension termination instruction for a magnetic bearing; and respectively applying a control current to one or more control coils of the magnetic bearing to subject a rotor to a vertically or slantedly upward electromagnetic force having a vertical component smaller than the gravity force on the rotor. The present invention also discloses a magnetic bearing control device comprising an acquisition unit of a suspension termination instruction and an application unit of a control current. The magnetic bearing control method and control device can decrease a dropping speed of a rotor compared to the condition of the rotor being subjected only to the gravity force, and have high control efficiency.
