Abstract
A machine includes a moving part and a direct drive for moving the moving part. The direct drive includes a stator and an armature unit which interacts with the stator. A coupling device couples the armature unit to the moving part to allow a movement of the moving part in relation to the armature unit. The direct drive further includes a spacer device to maintain a distance between an active region of the stator and an active region of the armature unit, thereby defining the air gap between the stator and the armature unit.
