ABSTRACT:
The kinetic energy of an intermittently movable work member is converted, independently of its main drive motor, to potential energy during deceleration of the work member as it approaches each of its dwell positions. During the initial portion of the next index step, the stored potential energy is imparted to the work member, again independently of the drive motor, to assist in the work member's acceleration and to reduce the demands on the drive motor. Since the energy storage and transfer occurs independently of the drive motor, armature current and temperature increase in the drive motor is minimized for any given performance level.
