ABSTRACT:
The present invention is an improved coating roll drive that used frameless, inside out motor and a set of magnetic bearings, axial and radial, mounted inside a coating roll to provide adaptive positioning of the coating roll relative to a given reference, such as a hopper lip. The present invention minimizes the variation of distance between the coating roll and the given reference during operation.
