Industrial Applications

1. High-Speed Automated Packaging Lines

This servo motor serves as the prime mover for synchronized multi-axis operations in packaging machines, handling tasks like rotary cutting, cross-sealing, and index feeding that require precise continuous acceleration.

Problem Solved

Conventional absolute encoders rely on batteries, introducing a point of failure and maintenance downtime. The R88M-1L3K030C-S2 utilizes a battery-free 23-bit encoder that inherently solves this maintenance bottleneck, while its 28.7 Nm peak torque effortlessly handles dynamic load shifts during rapid start-stop cycles without stalling.

2. Heavy Payload Cartesian Gantry Systems

Integrated into XYZ cartesian robots or high-payload gantries used for end-of-line material handling, stacking, or automotive parts palletizing.

Problem Solved

Moving heavy, cantilevered loads quickly requires significant mechanical rigidity and torque control. This motor guarantees smooth load transition via its reliable 9.55 Nm rated torque, while the 130 mm square flange and robust 22 mm keyed shaft resist extreme torsional strains.

3. Precision CNC Machine Positioning

Provides rotational drive to the primary X and Y ball screws of precision CNC routing or metal-cutting centers, facilitating smooth, continuous motion at fluctuating feed rates.

Problem Solved

CNC machinery demands micro-level accuracy to prevent machining errors. The 23-bit absolute encoder feeds back millions of counts per revolution, preventing position drift. The robust 400 V three-phase power and 3000 RPM operation maximize rapid traverse speeds, drastically cutting non-cutting cycle times.
