Product Description:

The D082M-13-1310 is a direct-drive rotary motor produced by Kollmorgen as part of the DDR Direct Drive Motors series. It serves as a frameless servo element that mounts directly to machinery frames, eliminating belts or gearboxes in indexing tables, wafer handlers, and similar precision axes. By integrating the rotor to the load through a straight-through bore and face coupling, the unit delivers zero-backlash torque that supports high-accuracy motion in industrial automation.

The motor delivers a continuous torque of 25.9 N·m at 40 °C, which is the steady load it can support without overheating. For short bursts, the peak capability rises to 92.2 N·m, allowing fast acceleration of inertial loads. A maximum operating speed of 300 rpm sets the top shaft velocity when driven from the 115/230 VAC winding. Dynamic response is influenced by the rotor inertia of 0.0194 kg-m², and lower inertia helps shorten settling times. Position feedback is supplied by a sine encoder that resolves 134,217,728 counts/rev, while its inherent accuracy is held within ±26 arc-sec. These electrical and mechanical characteristics combine with the single-bearing stack, the 8.60-inch outside diameter, and the 90° rotatable power and feedback connector to simplify integration on face-mount interfaces.

Repeatable positioning is ensured because the encoder returns the same angle within <1 arc-sec on successive moves, supporting tight registration tasks. Thrust loads up to 3,360 kg can be transmitted through the axial bearing without degrading life, so vertical tables or press drives can be handled directly. Despite this load capacity, the assembly weighs only 21.5 kg, reducing inertia on supporting structures. A non-sealed housing completes the mechanical envelope and allows services to be routed through the hollow core while maintaining a compact footprint.
