Product Description:

The D102M-22-1310 is a rotary direct drive motor produced by Kollmorgen within the DDR Direct Drive Motors series. It employs a single bearing arrangement to keep axial and radial runout low while simplifying maintenance. A flange mount interface allows the housing to bolt directly to machine frames, and the straight-through bore shaft style permits cable routing or pneumatic lines through the motor center. Mid-stack lamination geometry balances torque density with thermal mass, and a straight connector simplifies in-cabinet wiring.

The drive section delivers a continuous torque of 63.4 N-m for steady motion and can reach a peak of 210 N-m during acceleration events without exceeding thermal limits. Closed-loop speed is capped at 200 rpm, a value aligned with large-diameter rotary tables that favor precision over high velocity. Position feedback is generated by a high-resolution encoder that yields 2,097,152 counts/rev, enabling sub-micron linear interpolation when paired with fine lead gearing. Repeatable bidirectional positioning error remains within ±0.62 arc-sec, and the rotor’s reflected inertia of 0.0992 kg-m² contributes to smooth servo response while still withstanding up to 5,300 kg of axial compression. An 11.19-inch frame outside diameter offers a generous mounting footprint without encroaching on workspace.

Overall system accuracy is specified at ±26 arc-sec, supporting contouring applications where accumulated error must stay below one encoder count across multiple indices. The assembly weighs 43.8 kg, so machine structures must account for this static mass as well as the dynamic loads created by peak torque events. Dual-rated windings accept a supply of 115/230 VAC, allowing the same motor to integrate into low- or high-voltage plants without rewinding. The motor is suitable for precision rotary stages, indexing heads, and semiconductor handling axes.
