Kollmorgen CH041A-13-3305
Product Introduction:
The Cartridge DDR is a frameless-style direct-drive rotary motor pre-assembled into a stainless-steel cartridge housing with bearings, rotor, stator, and high-resolution encoder—combining the compactness of frameless technology with the ease of installation of a housed motor. CH041A-13-3305 indicates a size-041 cartridge with specific winding (A), shaft seal, stack length, and EnDat or similar feedback.
Detailed content

-
Peak Torque: up to ~12.3 Nm
-
Continuous Current: ~2.7 A RMS
-
Max Speed: approx. 1700 rpm (winding dependent)
-
Feedback: Single-turn EnDat 27-bit or similar high-res encoder (model-specific)
-
Bore: hollow-shaft design for cable pass-through
-
Degree of Protection: IP65 (with shaft seal)
-
Connectors: 2× angled rotatable M23 connectors
-
Rotor/Material: Rare-earth Neodymium-Iron-Boron (NdFeB) magnets; aluminum alloy housing
Features:
-
Zero-backlash direct drive—no coupling, gearbox, or belt
-
Hollow-shaft for cable management through the center
-
Pre-aligned bearing system—no separate bearing design needed
-
High-resolution absolute feedback for precise positioning
-
Low cogging torque
Applications: Rotary indexing tables, semiconductor wafer handlers, laser marking heads, pick-and-place theta axes, metrology rotary stages.
Installation Notes: Bolt directly to machine frame using pilot diameter and mounting bolt pattern; align load to hollow bore with tight concentricity tolerance; do not exceed max axial/thrust load on bearings; use flexible coupling or bonding for hollow-shaft cabling.
