MKD090B-047-KP2-KS

The MKD090B-047-KP2-KS is an AC servo motor produced by Bosch Rexroth Indramat within the MKD Synchronous Motors series. It serves as a closed-loop drive element that converts electrical power from an inverter into regulated rotational motion for automated machinery. By combining permanent-magnet excitation with internal position feedback, the motor allows controllers to execute precise speed, torque, and positioning commands required in material handling equipment, pick-and-place gantries, and packaging stations.

A centering diameter of 110 mm fits the motor accurately to mounting adapters and maintains concentricity between the rotor and the driven load. Power and feedback leads exit through a Side B interface, and the terminations are protected inside a Connection box, simplifying cabinet routing. At a locked shaft, the unit can deliver 12.0 Nm of continuous torque without exceeding thermal limits, giving machines stable holding force during dwell periods. Rotor angle is reported by a resolver feedback device that is integrated with the encoder housing, providing analog sine-cosine signals for drive commutation and velocity estimation even in electrically noisy environments.

The square 140 mm flange follows an IEC pattern so the motor can bolt directly to gearheads or mechanical frames without custom plates. Torque is transferred through a shaft with keyway, and a shaft seal prevents lubricant ingress from the connected machinery. Multi-turn monitoring supports Absolute (>4096 revs) position detection, enabling homing-free startup and reliable recovery after power loss. Winding code 047 defines the conductor gauge and turns per phase, matching the motor to drive modules that supply the correct voltage and current. The size 090 stator and length B stack give a compact form factor while still accommodating the thermal mass and copper necessary for continuous duty cycles.
