Product Description:
The C041A-13-3305 is a frameless direct-drive rotary motor produced by Kollmorgen within the Cartridge DDR Motors series. Designed to embed directly into machine structures, this cartridge-style unit eliminates belts and gearboxes and delivers precise torque for indexing tables, electronic assembly heads, and similar automation axes. Its cartridge mounting simplifies installation by integrating the stator into a pre-machined housing while the rotor clamps to the load shaft, reducing alignment effort and total system inertia. Because the motor is frameless, it becomes part of the machine structure rather than a separate housed assembly, which helps support compact rotary axis layouts.
The motor delivers a continuous stall torque of 4.57 N-m while drawing a continuous stall current of 2.73 Arms. These values show the steady load the axis can hold without excessive heating. The phase inductance is 34.4 mH, and with a DC resistance of 8.47 ohms it affects current rise time and copper loss. A rated line voltage of 240 VAC energizes the windings and produces a back-EMF constant of 102 Vrms/kRPM, which helps keep regenerative voltage within bus limits when the drive is selected. Position and velocity are reported through a digital BiSS interface for closed-loop control, while the split ring coupling shaft style centers the rotor and the 90° rotatable power connector eases cable routing. Total motor mass is 4.08 kg, helping keep moving-axis load low, and a torque constant of 1.68 N-m/Arms links commanded current to developed torque.
The transient capability is markedly higher than the continuous ratings, with peak stall torque reaching 12.3 N-m while the drive may supply 8.19 Arms for short bursts. With a rated speed of 1750 RPM, the motor develops a mechanical output of 775 W, allowing medium-power axes to accelerate and settle quickly. System responsiveness is helped by the rotor inertia of only 0.000586 kg-m², which helps limit overshoot during direction reversals.
