Product Description:
The D081M-12-1310 is a direct-drive rotary motor manufactured by Kollmorgen within the DDR Direct Drive Motors series. The unit integrates the stator and rotor into a compact ring frame so loads can be coupled directly to the bore, eliminating the need for mechanical transmission components. By providing high torque at low speed, it supports indexing tables, semiconductor handlers, and other automation stations that benefit from smooth, precise positioning. Direct coupling also reduces backlash and removes transmission components that could otherwise introduce compliance into the motion system.
Under continuous duty at 40 °C, the motor delivers 15.9 Nm of steady torque and can reach a peak output of 45.0 Nm for short acceleration bursts. A single bearing stack supports these torque levels and is rated for an axial compression load of 3,360 kg, allowing vertical loads to be mounted directly to the flange. The rotating mass has an inertia of 0.0144 kg-m², so servo loops can achieve fast settling without aggressive gain settings. The rotor can spin at up to 500 rpm before reaching its voltage and back-EMF limits. Position feedback comes from a sine encoder that supplies 134,217,728 counts per revolution, enabling sub-arc-second interpolation and smooth sinusoidal commutation through high-resolution drives.
The motor has a 218.4 mm outer diameter and a flange-mount interface. Its straight through-bore shaft uses face coupling, allowing pallets or rotary platens to attach without additional hubs. The system accepts 115/230 VAC and accommodates common servo amplifiers, while the motor’s total mass is 17.9 kg. Position measurement has an absolute accuracy of ±26 arc-seconds and repeatability of less than 1 arc-second, giving the controller predictable bidirectional positioning. Because the motor has a nonsealed housing, it must be protected from coolant and debris ingress. The open housing configuration also reduces drag losses and limits thermal rise during operation.
