Title:
簡易配線を有する磁気軸受装置
Document Type and Number:
Japanese Patent JP4767954
Kind Code:
B2
Abstract:
A magnetic bearing device and a method of operation for such a device are provided. The device comprises a group (410) of electromagnetic actuators (411, 412, 413, 414). Each actuator is electrically connected to an amplifier unit (701). The actuators of a first subgroup are connected to a first common node (608), while the actuators of a second subgroup are connected to a second common node (609). The common nodes (608, 609) are connected either directly or through means like an additional actuator. Either the common nodes (608, 609) have no additional electrical connection to the amplifier unit, or additional electrical connections may be present. In the latter case, however, the amplifier unit ensures that currents through the additional connections are lower than the sum of the absolute values of the currents through all actuators. The invention enables simplified wiring without increased load requirements for the wires.
