Product Description:
The D101A-23-1210 is a direct-drive rotary motor produced by Kollmorgen for the DDR Direct Drive Motors series. This frameless torque unit eliminates belts and gearheads by coupling its rotor directly to the load through a straight through-bore with a face coupling. In high-precision positioning tables, indexers, and semiconductor tools, it provides smooth, low-cogging motion, while the flange mount simplifies machine integration. The unsealed housing and single internal bearing are intended for clean, protected enclosures where the host machine provides external sealing.
For continuous duty, the motor delivers 40.7 N·m of torque and can reach a short-term peak of 129 N·m during rapid acceleration. Its maximum speed is 300 rpm, allowing direct coupling to moderate-speed rotary stages without reduction. Position data are captured by a feedback device with a resolution of 134,217,728 counts per revolution. This resolution is paired with a feedback accuracy of ±135 arc-sec, allowing the drive to command small incremental movements with minimal following error. The windings support 115/230 VAC excitation through a compatible servo amplifier. A power and signal connector can rotate 90 degrees to assist cable routing in confined cabinets, and the short rotor stack reduces the required space behind the load.
The motor supports an axial compression load of 5,300 kg, making it suitable for vertically loaded index plates or hollow-shaft presses. Dynamic response is influenced by a rotor inertia of 0.0693 kg·m², which balances rapid acceleration with drive current demand. The frame has an outside diameter of 11.19 in, providing a large bolt circle for rigid mounting while fitting within standard semiconductor cluster-tooling envelopes. Feedback repeatability is ±2.4 arc-sec, supporting consistent bidirectional homing during repeated positioning cycles. The rotatable connector maintains cable strain relief across different installation orientations without increasing the motor’s axial footprint.
