Product Description:

The MKD112B-048-KP2-BN is a servo motor manufactured by Bosch Rexroth Indramat and included in the MKD Synchronous Motors series. Built for industrial automation axes, it converts drive-controller power into controlled rotary motion while sending position data back to the control loop. The design supports precise speed regulation, quick indexing, and consistent torque delivery in packaging, material-handling, and general assembly equipment where closed-loop performance is required. Because feedback is returned continuously during operation, the connected drive can correct for changing load conditions and keep motion stable through acceleration and deceleration. That behavior is useful on stations where the axis must follow short move profiles, hold a commanded position for a brief dwell, and then restart without noticeable lag.

Mechanical interfacing starts with a centering diameter of 130 mm that seats the housing concentrically on the mounting surface, while the rectangular flange spans 192 mm to match standardized bolt patterns. Power and feedback leads exit on side B through an output connector, simplifying cable routing in cabinets arranged for right-hand service access. Under continuous duty, the motor supplies 28.0 Nm of standstill torque, which supports direct coupling to medium-inertia loads without external gear reduction. The B length keeps torque capacity in balance with overall motor mass, and a factory-installed shaft seal helps limit the passage of lubricant and contaminants at the motor-to-gear interface. Accurate concentric seating also helps reduce vibration from coupling misalignment, which is important when the shaft is connected directly to a load rather than through a reduction stage.

Signal quality is maintained by resolver feedback integrated into the rear cover, and it reports multi-turn position as an absolute value exceeding 4096 revolutions for homing-free startup. The rotor uses a shaft with keyway, so torque can be transmitted through standard keyed couplings and similar hubs in splash-prone machine areas. Electrical behavior is set by winding code 048, which matches the voltage constant and rated current to compatible digital drives. With frame size 112 and multi-turn position reporting, the motor supports repeatable indexing in feeders, tool changers, and pick-and-place axes, and the keyed shaft allows positive torque transfer during frequent starts, stops, and direction changes. This arrangement suits applications that need reliable position retention after shutdowns and straightforward coupling to driven elements such as pinions, timing pulleys, or compact gear units.
