Industrial Applications

1. High-Speed Pick-and-Place Gantry System

Utilizing the R88M-1M40030T-S2 on the X and Y axes of a gantry robot for assembling small electronic components. The motor's high speed and precise positioning are critical for rapid and accurate placement.

Problem Solved

The 3000 r/min rated speed allows for fast travel between pickup and placement points, significantly reducing cycle time. The 23-bit absolute encoder ensures that components are placed with extreme accuracy, minimizing assembly errors and waste. The battery-less encoder design reduces maintenance by eliminating the need for battery replacements.

2. Automated Labeling Machine Actuation

Driving the label applicator head and the conveyor feed on a high-throughput packaging line. The servo motor ensures labels are applied precisely and consistently on products moving at high speeds.

Problem Solved

The motor's ability to sync with the conveyor speed while delivering 1.27 Nm of rated torque ensures the applicator has enough force and responsiveness to apply labels without slipping or misaligning, even during rapid acceleration/deceleration. The absolute encoder guarantees repeatable positioning for every product, which is crucial for brand presentation and barcode scannability.

3. CNC Milling Spindle Auxiliary Axis Control

Controlling an auxiliary rotary axis (A-axis) on a small CNC milling machine for creating complex curved surfaces on plastic or aluminum parts. The motor's compact size and torque are ideal for this application.

Problem Solved

The motor's 60mm flange and overall compact size allow for easy integration into a crowded machine head. The 4.5 Nm peak torque provides sufficient power for light milling and drilling operations, while the 23-bit encoder allows for the fine angular adjustments needed for machining smooth, complex geometries with high precision.
