Abstract

An electromagnetic single-surface clutch/brake combination, especially for textile machinery, in which a rotor assembly is locked to the shaft end encloses the magnetic body carrying the coils so that the latter can be secured to the housing flange when the unit, as delivered, is mounted on the shaft. The rotor assembly and the magnetic body are bridged by a bearing.
