Patent ID: 8796893

Claim:
Apparatus having a directly driven rotating body including a first face side, a second face side opposite the first face side, and a circumference, radially seated on radial bearings in relation to a stationary body and axially seated relative to the stationary body, with aerostatic bearings providing axial support mounting between the first face side and the stationary body, wherein the directly driven rotating body includes an annular magnet arrangement asymmetrically arranged on the first face side with respect to the second face side, which is configured coaxial relative to an axis of rotation of the rotating body, and the stationary body has at least one electric coil arrangement located opposite the annular magnet arrangement in the axial direction and defines with the annular magnet arrangement components of an electrical direct drive for the rotating body such that in use attractive forces are present between the annular magnet arrangement and the at least one electric coil arrangement to forcibly support the aerostatic bearings between the first face side and the stationary body, the stationary body is formed by a rotating gantry of the imaging apparatus, and, the rotating body is formed by a rotating gantry of the imaging apparatus.
