DRIVE SYSTEM ABSTRACT OF THE DISCLOSURE A journal of a drying cylinder or the like, in a paper, cardboard or coating machine, is mounted in a bearing housing which is supported in fixed position on a frame. A hollow, cylindrically widened housing for an electric drive motor is formed as an extension of the bearing housing toward the drying cylinder. This motor housing, together with the bearing housing, forms a continuous outer surface for the drive system. The motor is a permanent-magnet motor whose stator has electromagnet poles which are arranged in the hollow cylindrical housing. Its rotor has permanent-magnet poles, which form a hollow cylindrical ring mounted on the circumference of the journal. The drive system consists of only a few parts, requires only a small amount of space for installation, and is easily and inexpensively serviceable.
