ABSTRACT:
An integrated rotary drive apparatus for driving an element to be rotated in a controlled manner, comprises; a coupling shaft coupled to the element to be rotated, a drive shaft having a hollow portion within which the coupling shaft engages, a shaftless DC motor armature coupled to the coupling shaft for directly driving the coupling shaft, and a flywheel and rotary encoder disk coupled to the drive shaft to rotate therewith. The integrated rotary drive further includes a first enclosure section, for mounting to a non-rotating frame member for supporting the integrated rotary drive, and a second enclosure section mounted to the first enclosure section, for supporting a non-rotating optical encoder reader in proximity to the rotary encoder disk for providing a feedback signal, and for supporting a non-rotating DC motor stator in proximity to the DC motor armature for driving the DC motor armature when a DC current is applied to the stator.
