Product Description:

The D101M-22-1310 is a direct-drive rotary motor built by Kollmorgen within the DDR Direct Drive Motors series. It delivers closed-loop torque control and arrives as a fully housed assembly for straightforward machine integration. In automation systems, the unit replaces gearboxes by producing high torque at low speed, allowing indexers, printing tables, and semiconductor stages to position loads with minimal mechanical compliance. Flange mounting and a through-bore shaft permit utilities to pass through the axis while keeping the footprint compact.

At 40 °C, the motor can supply a continuous output of 34.6 Nm, a base value used to size the drive amplifier for steady-state duty. During rapid indexing, it withstands a peak torque of 129 Nm, enabling short bursts of high acceleration without thermal overload. Speed is electronically limited to 300 rpm, so the direct coupling maintains accuracy without an intermediate reducer. The low rotor inertia of 0.0693 kg·m² shortens settling time when the axis reverses. Position data come from a sine encoder with a native resolution of 134,217,728 counts/rev; together with ±26 arc-sec feedback accuracy, the drive can execute fine contour moves. A single bearing set supports the rotor, and the straight through-bore shaft with face coupling simplifies fixture attachment. The flange mount aligns the motor to the machine datum, while a straight power-feedback connector expedites cable routing. Because the unit is not sealed, installation inside a clean enclosure is required.

A thrust rating of 5,300 kg in axial compression lets vertical tables or presses rest on the bearing stack without auxiliary supports. The 284.2 mm frame diameter offers a wide bolt circle that resists torsional deflection. Repeatability of <1 arc-sec enables pick-and-place heads to return to the same coordinate. With a mass of 31.5 kg, the assembly stores thermal energy that damps temperature swings during intermittent duty.
