Product Description:

The MKD112D-027-KG0-BN is a servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. As a rotary actuator, it translates drive current into controlled mechanical motion for CNC axes, packaging machines, and automated handling stations. The unit’s resolver-based feedback and integrated electronics let the corresponding drive regulate position and velocity in closed-loop mode, while its brushless construction reduces routine maintenance in continuous industrial duty. This makes the motor suitable for applications that need repeatable positioning, stable speed control, and responsive torque output under changing load conditions.

The motor supplies up to 48.0 Nm of continuous standstill torque, giving machines steady holding force during low-speed tasks such as indexing, tension control, and controlled axis holding. Mechanical centering on a 130 mm pilot diameter aligns the motor accurately with load-side components and helps limit radial runout at the coupling. Power and feedback lines exit on Side B, and an output connector simplifies cable connection without rewiring terminal strips during service. Motion feedback is delivered through resolver feedback, which withstands vibration and high temperatures better than many optical devices. The design omits a holding brake, so static torque or external clamping is required to secure the axis when power is removed.

A square 192 mm mounting flange matches DIN dimensions for gearboxes and machine frames, while the D length code increases stack height for higher power density without changing the bolt circle. Absolute position detection of more than 4096 revolutions eliminates homing routines after startup and supports multi-turn monitoring in gantry systems and other long-travel axes. Output torque is transferred through a plain shaft that reduces backlash when coupled with friction hubs, and a shaft seal helps keep lubricants inside the machine housing. The shaft seal also helps protect the bearing area from contamination in enclosed machine installations. Thermal and electrical behavior correspond to winding code 027, so the drive controller can apply the correct current limits and temperature models.
