Abstract
Direct drive motor, particularly for disk storage drives, spindle drives and the like, with a rotor shaft rotatably mounted in a bearing support by two axially spaced bearings, whose outer rings are fixed with respect to the bearing support. The inner ring of one bearing is fixed to the rotor shaft and the inner ring of the other bearing is connected to the rotor shaft in friction fit manner, which prevents radial movements and permits a relative axial movement between the inner ring and rotor shaft.
