Internal Product Review
The DH102A-22-1210 is a Kollmorgen DDR direct drive motor configured for flange mounting and a straight thru bore with face coupling. Continuous torque of 74.6 N-m and peak torque of 227 N-m give the motor excellent authority in demanding rotary applications. Resolver feedback and 300 RPM maximum operating speed make the package a strong choice for accurate, low-speed direct-drive motion.

Product Description:
The DH102A-22-1210 is a Kollmorgen rotary direct-drive motor that belongs to the DDR Direct Drive Motors series. This frameless, permanent-magnet unit mounts by flange to the machine structure and couples directly to the load through its straight through-bore shaft, eliminating belts or gearboxes in high-precision automation. Powered from a 3-phase 400/480 VAC winding, the design combines a single bearing stack with resolver feedback so the motor can send precise position data to a servo drive while keeping the overall envelope compact. This arrangement helps reduce backlash and mechanical compliance that can appear in transmission-based drive systems.
At 40 °C, the stator can produce a continuous torque of 74.6 N-m, and for rapid indexing it reaches a peak output of 227 N-m without exceeding thermal limits. Motion response is influenced by a rotor inertia of 0.0992 kg-m², which supports stable acceleration profiles when paired with a compatible drive. The electromagnetic stack supports a maximum operating speed of 300 RPM, which suits large-diameter tables where linear velocity comes from radius rather than shaft speed. Positioning capability is supported by a system repeatability of ±2.4 arc-sec, and resolver interpolation provides a digital resolution of 134,217,728 counts/rev for very fine command tracking. The motor uses the A resolver type and comes in a short-stack configuration to reduce axial length.
Mechanical integration benefits from an axial compression capacity of 5,300 kg, permitting the table or platen to carry substantial vertical loads without external thrust bearings. The housing diameter measures 11.19″ O.D., matching common rotary stages, and the unit mass is 43.8 kg, which should be considered when sizing the support structure. A straight, face-coupled bore simplifies fixture attachment, and the single-bearing layout reduces maintenance points compared with more complex bearing arrangements. Because the motor is unsealed, the installation area should remain free of coolant spray and airborne contaminants.
