Kollmorgen Cartridge DDR Direct Drive Rotary Servo Motors
The Kollmorgen Cartridge DDR (C-DDR) Servo Motor Series (featured model: C052A-11-1100 22 Nm 700 RPM) is an innovative motion control solution that combines the extraordinary performance advantages of a frameless direct drive rotary motor with the effortless installation of a standard factory-assembled servo motor. By mounting directly onto the machine load shaft using a patented compression coupling, Cartridge DDR motors completely **eliminate mechanical gearboxes, timing belts, pulleys, and flexible couplings**, achieving true **zero backlash, zero compliance, and maintenance-free operation**. Featuring factory-integrated high-precision bearings and high-resolution optical / sine-cosine feedback encoders (up to 2,097,152 counts/rev), C-DDR motors deliver continuous stall torque output from 4.5 Nm up to 510 Nm across 5 distinct frame sizes (C04, C05, C06, C09, C13). Optimized specifically for seamless autotuning with **Kollmorgen AKD and AKD2G digital servo drive amplifiers**, Cartridge DDR motors serve as the ideal direct-drive replacement for mechanical rotary indexing tables, printing press cylinders, semiconductor wafer handlers, and high-precision packaging machinery.

Mechanical Gearbox & Belt Drive to Cartridge DDR Direct Drive Upgrade Guide
Mechanical rotary indexers, planetary gearbox drives, and timing belt assemblies can be upgraded to Kollmorgen Cartridge DDR motors for zero-backlash direct-drive positioning:
| Legacy Mechanical Drive System | Mechanical Limitations | Current Cartridge DDR Equivalent | Key Performance & Reliability Upgrades |
|---|---|---|---|
| Servo + Planetary Gearbox Assembly | Gear backlash (3-10 arcmin), wear, lubrication maintenance | Kollmorgen C041A / C052A C-DDR Zero Backlash | Direct load coupling, eliminates gear wear, maintenance-free continuous operation. |
| Servo + Timing Belt & Pulley System | Belt stretch, compliance, periodic tensioning required | Kollmorgen C052A / C063A C-DDR High Stiffness | Infinitely stiff coupling, precise positioning, eliminates belt replacement downtime. |
| Mechanical Cam Rotary Indexer | Fixed index angles, mechanical wear, loud operation | Kollmorgen C063A / C092A C-DDR Flexible Indexing | Programmable index angles via AKD drive, ultra-quiet, rapid motion profile changes. |
| Frameless DDR Motor (Bare Stator/Rotor) | Complex factory bearing/encoder mounting required | Kollmorgen C092A / C131A C-DDR Factory Assembled | Pre-aligned factory bearings and encoder, mounts in under 30 minutes via compression hub. |
