Printing & Packaging — Direct Drive Applications

Printing and packaging machinery pursue high-speed, precise synchronized motion and long-term stable continuous operation. Torque motors directly drive rotary axes with zero backlash and excellent synchronization, ensuring print registration and packaging cadence; segmented motors suit large-diameter rollers, and linear motors drive high-speed reciprocating axes — all maintenance-free.

Requirements

Drive Challenges in Printing & PackagingDrive challenges in printing & packaging

Rotary rollers and reciprocating axes impose strict requirements on synchronization, dynamics, large diameter and reliability.

High Dynamics & SynchronizationHigh Dynamics & Synchronization

RIB / RKI excellent synchronization

Print registration and packaging cadence require precise multi-axis synchronization. RIB offers high dynamics with low torque ripple, and RKI combines high power output with excellent synchronization and low power loss, directly driving rotary axes to ensure registration accuracy and consistent cadence.

Large-Diameter Rotary AxesLarge-Diameter Rotary Axes

Segmented: large diameter economically viable

Large printing rollers and packaging turntables have large diameters. Segmented motors design the primary / secondary parts as segments, scaling torque via the number of segments to make very large diameters economically viable, with redundant design and reduced maintenance needs.

High-Speed Reciprocating AxesHigh-Speed Reciprocating Axes

Linear motors high acceleration/deceleration

The conveying, cutting and labeling of packaging require high-speed reciprocating motion. L1 iron-core linear motors are explicitly listed for packaging and food processing, with high acceleration/deceleration capability and excellent constant velocity, driving high-cadence linear reciprocating axes.

Maintenance-Free Continuous OperationMaintenance-Free Continuous Operation

Zero backlash · maintenance-free

Printing and packaging lines run continuously for long periods. Direct-drive motors have no intermediate transmission elements, zero backlash, contactless wear-free operation and are maintenance-free, ensuring long-term stability and reliability under high-speed continuous production.

Printing

Printing Machinery Drive Axes

The core challenge of printing is balancing speed and quality simultaneously. The drive axes of printing machinery must maintain extremely low tracking error (below 1 µm) and low cogging at high speed, in order to maintain stable print quality without sacrificing speed. Direct drive eliminates intermediate transmission, achieving smooth, precise motion at high speed.

Speed & Quality Tracking Error < 1 µm Low Cogging

Packaging

Packaging Machinery & Turntables

The rotary turntables and indexing axes of packaging machinery require sufficient torque to drive and position the load, while maintaining stable synchronization and indexing accuracy at high cadence; large-diameter turntables further require high torque at large scale. Direct drive eliminates intermediate transmission, achieving smooth, precise rotation and indexing.
