Document Type and Number:
Japanese Patent JP2002504978
Kind Code:
A
Abstract:
A flux position sensor for magnetic bearings applications is provided by creating a secondary, or shunt, flux path in parallel with a main flux path of a magnetic bearing. The secondary flux path is formed such that a small amount of bearing magnetic flux is shunted from the main path into the secondary path. The amount of shunted flux varies in a known relationship with the flux density and/or the position of the element being supported by the bearing. By quantifying the amount of shunted flux, using any number of conventional methods, the position of the supported element can be determined. Therefore, the flux position sensor forms an integral part of a closed loop control system for an active magnetic bearing. The same sensor can be used simply for measuring flux density in a magnetic bearing or other device.
