Abstract
A viscometer for inline determination of the viscosity of a fluid includes a drive device and a measuring device including a housing and a chamber. The drive device includes a housing in which a stator is arranged. The stator has and having a plurality of coil cores delimited by an end face, and carrying a concentrated winding, and being a bearing and drive stator with which the rotor is magnetically driven without contact and magnetically levitated without contact with respect to the stator. A control device actuates the stator and determines the viscosity based on an operating parameter of the electromagnetic rotary drive.
