Product Description:
The CH043A-13-3105 is a frameless cartridge direct-drive rotary motor produced by Kollmorgen for the Cartridge DDR Motors series. Its stator slides into a precisely machined bore while the rotor clamps to the load shaft, removing belts and gearboxes from the drivetrain. This arrangement supplies direct, high-precision rotation for indexing tables, robotic joints, and other industrial automation axes that require tight positioning and repeatable torque.
With a 480 V AC bus, the motor sustains a continuous stall torque of 11.1 N·m while drawing 4.73 A rms, establishing the thermal limit that servo drives must respect. The winding can deliver a rated mechanical output of 2402 W at 2500 rpm, so moderate-power loads can be coupled without speed reduction. The motor reaches an IP65 protection rating after the mounting face and gaskets are installed, protecting the internal laminations from dust and sprayed fluids. Phase resistance is 3.97 Ω at 25 °C, and the 90-degree rotatable connector allows the power and feedback leads to be oriented for the machine layout. The 201.7 mm stator fits a 32 mm machine bore, and position data travels over an EnDat serial interface for high-resolution commutation. This feedback connection provides the drive with the position information needed to regulate motion accurately during indexing and continuous rotation.
For short bursts, the motor can generate a peak stall torque of 30 N·m, enabling rapid index moves before thermal limiting intervenes. Electromagnetic conversion efficiency is indicated by a torque constant of 2.37 N·m/A rms, while a back EMF constant of 143 V rms/krpm helps determine the drive voltage margin. Current-loop dynamics are influenced by an inductance of 20.6 mH, supporting stable regulation without external reactors. A rotor inertia of 0.00119 kg·m² supports fast acceleration and responsive changes in rotational speed. Motion is transferred through a split-ring coupling that grips the driven shaft directly, reducing compliance between the motor and load. The direct coupling also eliminates drivetrain components that could otherwise introduce backlash during repeated positioning cycles.
