Product Description:
The CH092A-11-1105S is a frameless direct-drive rotary motor produced by Kollmorgen within the Cartridge DDR Motors series. Designed to mount directly to a machine hub without bearings or couplings, the unit delivers high torque density for indexing tables, coil winders, and servo-controlled packaging axes. By integrating stator windings and feedback into a single cartridge that bolts to the load, the device eliminates belts and gearboxes, reducing compliance and maintenance in industrial automation.
Under steady load, the device develops a continuous stall torque of 101 N-m while drawing 15.3 Arms; this torque-to-current ratio results from the winding’s torque constant of 6.8 N-m/Arms. When driven from a three-phase supply at 400/480 VAC, the stator inductance of 11 mH limits ripple current and helps the servo drive regulate phase excitation. Electrical back-electromotive force reaches 441 Vrms/kRPM, so the selected drive must accommodate the generated voltage during rapid deceleration. The copper resistance measured at 25 °C is 0.921 Ω, and a heating factor of 1.4 indicates the relationship between temperature rise and power losses. A 406 × 406 × 19 mm heat sink can be attached to keep the windings within their thermal class limits. Adequate airflow around the heat sink is necessary to prevent trapped heat from reducing continuous performance.
For brief dynamic events, the motor can deliver up to 227 N-m of torque at standstill when the drive supplies a momentary current of 40 Arms; this headroom assists with breakaway loads and short acceleration bursts. The laminated rotor has an inertia of 0.047 kg-m², permitting quick speed changes without excessive overshoot when combined with the 38-pole magnetic structure. Mechanical losses are low, with static friction rated at 2.7 N-m and viscous damping rated at 0.45 N-m/kRPM, allowing precise velocity regulation. The motor weighs 41.3 kg, so the gantry, bracket, hub, and shaft components must support its mass safely. Direct attachment to the load also requires accurate alignment between the rotor, stator, and machine hub to prevent uneven air gaps during rotation.
