Magnetic bearing arrangement for a godet roll for guiding at least one yarn

摘要

A godet roll for guiding at least one yarn on the circumference of a hollow-cylindrical godet roll casing. The godet roll casing is rotatably seated on a projecting support by a bearing arrangement which includes a radially acting magnetic bearing having a plurality of bearing pole windings distributed in the circumferential direction on the support. The bearing pole windings are arranged on the support at spacings from one another circumferentially about the support and also at spacings along the support in a plurality of adjacent bearing planes in order to make possible a low-vibration guidance of the godet roll casing.
