Product Description:
The MKD112B-048-KP0-RN is a servo motor produced by Bosch Rexroth Indramat as part of the MKD Synchronous Motors series. It is engineered to interface with drive controllers in automated assembly cells, conveyor modules, and metal-cutting equipment where consistent torque delivery and repeatable positioning are essential. By pairing permanent-magnet excitation with internal resolver feedback, the unit supplies continuous commutation data so the control system can regulate shaft speed and angular position without open-loop drift.
The motor delivers a continuous standstill torque of 28.0 Nm, allowing it to maintain load holding without overheating when the axis is clamped or slowly indexing. A protection category of IP65 seals the stator housing against dust ingress and low-pressure water jets, so the motor can be mounted directly on machine frames without an additional cabinet. The stator flange measures 192 mm, and the centering pilot is 130 mm, enabling direct mounting to gearboxes or torque arms that share IEC sizing conventions. The aluminum frame corresponds to motor size 112 with length code B, which keeps inertia moderate for medium-duty cycles. Power and feedback leads exit on the right side through a single power connector, which simplifies cable routing alongside the machine bed. A keyed steel shaft transmits torque to couplings or pulleys.
The motor can run at ambient temperatures from 0–40 °C without derating, and its windings use Class F insulation to withstand the heat produced by repeated acceleration. Position data are retained by absolute tracking for more than 4096 revolutions, giving the drive immediate reference values after power-up. Closed-loop accuracy across the speed range is held within ±8 angular minutes, which meets common servo indexing tolerances on packaging and transfer equipment. A factory-installed shaft seal blocks coolant splash along the keyed output shaft, and the lack of a holding brake allows external clamping devices to be used when static locking is required. The rotor-stator assembly uses winding code 048, matching the electrical characteristics expected by MKD drives.
