Product Description:
The MKD041B-144-KP0-KS servo motor is manufactured by Bosch Rexroth Indramat and belongs to the MKD Synchronous Motors series. Intended for industrial automation, it converts drive commands into controlled rotary motion for positioning, feed, and auxiliary axes in machining centers, packaging lines, and material-handling cells. Its compact 041 frame size and electronically commutated design allow installation close to the load while maintaining stable speed regulation during continuous duty. This arrangement helps reduce transmission compliance in direct or short-coupled drive layouts, which supports accurate motion in repetitive machine cycles.
The motor supplies 2.7 Nm of continuous torque at standstill, giving the axis steady output during slow indexing or dwell periods. A square flange of 82 mm and a centering diameter of 50 mm align the housing accurately to gearheads or adapter plates, which helps limit radial misalignment at the shaft. Winding code 144 matches the electrical and thermal characteristics of this B-length housing to the intended drive combination. Rotor position is measured by resolver feedback with an integrated encoder, so the control loop receives robust analog sine-cosine signals that tolerate electrical noise and support closed-loop operation.
Power and feedback leads terminate in a connection box on side B, keeping cabling clear of moving machine elements and improving routing flexibility in compact installations. The unit is supplied without a holding brake, so external holding force is required when an axis must remain fixed after power is removed. An absolute (>4096 revs) position channel allows startup without a reference run, and the shaft with keyway provides positive torque transfer to pulleys or couplings. A fitted shaft seal protects the internal bearings and resolver from coolant splash and fine dust, which helps preserve running accuracy over time.
