Product Name: Cartridge DDR (Direct Drive Rotary) Motor, high-dissipation version
-
Introduction: Modular permanent-magnet synchronous torque motor for direct-drive rotary axes; eliminates gearbox, coupling and bearing stack. CH prefix denotes enhanced heat dissipation variant.
Detailed content
-
Technical Specifications: Frame size CH04; stack length 3; continuous torque 11.1 N·m (8.2 lb-ft); peak torque 30.0 N·m (22.1 lb-ft); max speed 2500 rpm (400/480 V system); rated voltage class 400/480 VAC; insulation class H; housing aluminum with stator lamination stack.
-
Functional Features: Zero-backlash direct drive; high torque density; low cogging; integrated rotor hub with mounting pilot; compatible with AKD/S700 servo drives.
-
Application Scenarios: Index tables, rotary actuators, optical inspection platforms, small CNC rotary axes, packaging machinery.
-
Structural Characteristics: Cartridge-style stator with through-bore rotor; single-bolt front-expansion hub mounting; hollow shaft option.
-
Installation Requirements: Mount on machined stator seat with controlled flatness; align pilot diameter; torque hub bolt to spec; avoid axial preload on bearings of driven load.
-
Usage Notes: Must be driven by Kollmorgen DDR-rated servo drive with correct motor file; do not operate above 2500 rpm; verify thermal derating in enclosed cabinets.
