MKD112B-048-KP0-BN
MKD Synchronous Motors
The Bosch Rexroth Indramat MKD112B-048-KP0-BN servomotor from the MKD Synchronous Motors series delivers high-performance motion control in a compact package. With a product type of Servo Motor and a motor size of 112, this unit balances power density and dynamic response. Its integrated resolver feedback with a Position Detection of Absolute (>4096 revs) ensures precise multi-turn positioning without external homing. The robust Shaft Design features a Shaft with keyway and Shaft Seal for enhanced mechanical integrity and reliable torque transmission.
In detailed operation, the MKD112B-048-KP0-BN sustains a Continuous Torque at Standstill of 28.0 Nm and a Maximum Speed of 4500 RPM, supporting rapid acceleration and deceleration profiles. It draws a Rated Current of 4.3 A per phase against a Resistance Per Phase of 0.12 Ω and an Inductance Per Phase of 2.2 mH, optimizing current loop bandwidth. The motor’s Weight of 24 kg and compact Motor Length designation of B facilitate integration into existing machine footprints. Natural Cooling Method by Natural convection eliminates additional auxiliary components, while the Connection Type via Output connector simplifies wiring.
Designed for seamless integration with Bosch Rexroth Indramat drives, the MKD112B-048-KP0-BN requires no additional holding brake, streamlining installation in applications with full electrical braking. Its precise encoder feedback and high torque-to-inertia ratio deliver exceptional responsiveness for indexing, winding, and pick-and-place operations. The absence of complex peripheral cooling systems, combined with robust mechanical design, ensures long-term reliability and reduced maintenance in continuous production environments.

Frequently Asked Questions
How much static holding is available for fixturing on MKD112B-048-KP0-BN?
It provides 28.0 Nm continuous torque at standstill. That capacity stabilizes clamped parts during long dwells or tensioned feeds, keeping position loops calm and minimizing thermal growth that could bias measurements in repeatable processes.
How does MKD112B-048-KP0-BN survive harsh bays with washdowns or airborne grit?
It meets IP65 protection class. Dust and water jets cannot penetrate the housing, preserving insulation resistance and resolver integrity so closed-loop control remains stable even when the surrounding environment demands frequent cleaning.
Which supply level should the inverter and protection coordinate around for MKD112B-048-KP0-BN?
It operates at 115 V nominal voltage. Matching bus hardware and drive modulation to that value maintains current headroom and switching efficiency, preventing saturation when the motion profile requires sharp accelerations or decelerations.
What property shapes acceleration tuning on MKD112B-048-KP0-BN?
It has 0.090 kgm² rotor inertia. That value tempers step responses, allowing assertive gains without overshoot, while still delivering crisp contouring in indexing tasks that combine frequent starts, stops, and reversals.
What ambient conditions should be assumed for enclosure and ventilation planning with MKD112B-048-KP0-BN?
It operates across 0 to 40 °C ambient. Cabinet airflow, cable derating, and load planning can align to this window to preserve winding life, avoid nuisance thermal trips, and maintain resolver accuracy.
