Product Description:

The D061M-12-1310 is a frameless rotary motor manufactured by Kollmorgen within the DDR Direct Drive Motors series. By eliminating gearbox stages, this direct-drive unit couples directly to the load and delivers precise position and speed control for indexing tables, semiconductor tools, and other automation axes. The motor uses a torque-dense stator and rotor set to drive machinery without mechanical backlash, supporting high-fidelity motion profiles in continuous-duty industrial environments.

At rated current, the motor supplies a continuous torque of 5.3 Nm, maintaining this output during constant-duty operation. Short bursts can reach 16.9 Nm, allowing acceleration of inertial loads without oversizing the drive. The rotor can spin up to 500 rpm when powered from its dual-rated 115/230 VAC winding, so one design can support either supply level. Motion feedback is provided by a sine encoder with an absolute resolution of 134,217,728 counts/rev; position error remains within ±26 arcsec, and repeatability is better than <1 arcsec. These values support highly accurate indexing in precision assembly, metrology, and optical positioning systems.

The single-row bearing set accepts dynamic axial forces up to 2040 kg, so the flange-mounted housing can support turntables or Z-axis loads without external thrust assemblies. With an outside diameter of 6.93 in and a rotor inertia of only 0.0061 kg-m², the unit balances a compact form with rapid acceleration for short cycle times on pick-and-place heads. A straight through-bore shaft with face coupling simplifies direct attachment to driven platters, while the straight power-feedback connector keeps cabling inline with the motor axis. Because the unit is not sealed, it should be installed in a clean enclosure or used with external sealing where fluids are present.
