Abstract
An apparatus and a method for determining the viscosity of a fluid includes an electrical rotary drive (2) with a stator (3), which has a stator winding (4), and with a rotational body (5) which can rotate in the fluid (1). The rotational body (5) is designed as a rotor (5) of the rotary drive (2) and is magnetically journalled in a contact-free manner with respect to the stator (3).
