Title:
磁気ベアリングの電気抵抗値の調整と磁気ベアリングに支承された物体のセンサレス位置測定のための方法
Document Type and Number:
Japanese Patent JP5661914
Kind Code:
B2
Abstract:
For an object on a bearing mounting having a magnetic bearing providing a magnetic field generally produced by an electromagnet, the bearing is regulated based on a position of the object relative to the bearing. The position of the object is determined by reference to an estimate of the inductance obtained using a least squares method, in which the electrical resistance of the bearing is taken into account. The resistance is subject to variations, for example due to temperature fluctuations; however, the electrical resistance can be estimated by regulating the inductance error, Δ{circumflex over (L)}={circumflex over (L)}2,sLS−{circumflex over (L)}1,sLS down to zero, where the resistance adjustment facility may be a low-pass filter and an integration controller.
