Like all gear units, servo gear units serve as converters of torque and speed and are therefore the central component of every servo gearmotor. The special feature of a servo gear unit: Thanks to its high torsional stiffness while maintaining a very low to constant rotational clearance, it enables extremely high acceleration and high torques. Servo gear units are therefore indispensable for plant operators whose applications require high positioning accuracy, short cycle times, exact speeds, high processing speeds, and maximum dynamics.
