Product Description:

The C043A-13-3105 is a direct-drive rotary motor produced by Kollmorgen for the Cartridge DDR Motors series. This cartridge-style unit integrates a stator, rotor, and preloaded bearings so that it can be inserted into a machine frame and secured with a simple compression ring. In industrial automation, it provides high torque at low speed, allowing indexers, rotary tables, and wrapping stations to move loads without gearboxes, thereby increasing positioning accuracy and reducing maintenance.

During continuous operation, the motor can deliver 11.1 N·m of stall torque while drawing 4.73 A rms of current; these values represent the thermal rating of the winding at an ambient temperature of 25 °C. Electrical reactance is governed by an inductance of 20.6 mH, which influences current rise time and the sizing of the amplifier’s current loop. The housing has an axial length of 232.7 mm, making it compatible with medium-format index platforms. The complete assembly weighs 7.26 kg, allowing direct mounting on lightweight aluminum frames. Copper resistance is 3.97 Ω at 25 °C, so steady-state power loss is predictable when the application demands near-stall operation.

The motor has a rated speed of 1250 rpm and a rated power output of 1343 W, resulting in a continuous rated torque of 10.3 N·m. For rapid acceleration, the electromagnetic stack produces a peak stall torque of 30 N·m, and transient current can reach 14.2 A rms without exceeding insulation limits. The steel rotor has an inertia of 0.00119 kg·m², supporting fast indexing while keeping servo gains moderate. A torque constant of 2.37 N·m/A rms corresponds to a back-EMF constant of 143 V rms/kRPM, supporting straightforward drive matching, while the 32 mm through-bore allows pneumatic or vacuum lines to pass directly through the motor. When the winding temperature rises by 70 °C, the available stall torque remains 9.63 N·m, providing predictable output over long operating cycles.
