Abstract
An axial compact direct drive for a storage disk comprises a stator, a rotor carrying a hub for receiving storage disks and a bearing arrangement. The bearing arrangement is disposed at a radially external edge of the hub to rotatably support the hub against axial and radial movement. The rotor is electrically driven at locations in the center of the stator or at locations surrounding the stator.
