Product Description:

The D083M-22-1310 is a rotary direct drive motor manufactured by Kollmorgen within the DDR Direct Drive Motors series. The unit mounts to machinery through a flange interface, and its straight through-bore shaft allows the driven component to couple directly to the rotor. By removing belts or gearboxes from the drive train, the motor can improve positional accuracy and reduce maintenance in semiconductor placement systems, indexing tables, and high-precision winding equipment. This layout also helps keep the mechanical path short, which supports responsive motion in automated lines.

At a winding temperature of 40 °C, the motor can deliver a continuous torque of 50.4 N·m, providing stable output for constant-duty cycles such as slow, heavily loaded table rotation. When faster acceleration is needed, it can reach a peak torque of 160 N·m, so the connected drive must accommodate that temporary demand. The maximum mechanical speed is 250 rpm, which suits applications that prioritize torque and positioning over high rotational speed. Application matching is aided by a rotor inertia of 0.0301 kg·m², helping the system respond to reversals without excessive lag. Power is supplied from a 230 VAC class bus, allowing use with standard industrial converter platforms.

The mechanical interface supports a dynamic axial compression rating of 3360 kg, so vertical turntables or pressing fixtures can be supported on the motor without added bearing hardware in suitable installations. Off-axis loading is tolerated up to an overturning moment of 53.3 N·m, which helps protect the frame under radial pull or cantilevered load conditions. Position feedback is provided by a single-turn absolute sine encoder, giving unique angular data for each revolution and allowing closed-loop operation without a homing cycle after startup. Internal rolling elements use a single-bearing arrangement, and the housing is non-sealed, so the installation must block fluid ingress or use external sealing measures. The straight connector orientation keeps cable routing low in height, which is useful where enclosure space is limited.
