Product Description:
The MKD025A-144-KG0-KN is a servo motor built by Bosch Rexroth Indramat for the MKD Synchronous Motors series. Designed for small-scale automation, it provides closed-loop rotary motion for indexing tables, feed drives, and compact handling modules. Typical duties include short indexing moves, feeder motions, and other repetitive positioning tasks that benefit from a small synchronous motor. The motor includes integrated position feedback and ships without a holding brake, so load retention during power loss must be provided by the drive or by external mechanics. Its compact mechanical layout suits timing belts, miniature gearboxes, or direct coupling to light load elements.
At standstill, the rotor can maintain 0.4 Nm of continuous torque, which indicates the thermal limit when the shaft is energized but motionless. The square mounting flange spans 54 mm, and the locating pilot measures 40 mm in diameter for accurate concentric alignment during assembly. Power, encoder, and protective earth leads exit on side B, keeping the application face clear for mounting hardware and couplings. All conductors terminate inside a sealed connection box, which protects screw terminals from dust and vibration while providing cable strain relief. This cable routing also separates the exit point from the mounting face, which can simplify access in dense assemblies.
The electromagnetic package follows winding code 144, which matches the motor to low-power inverters and keeps current demand appropriate for light mechanical loads. The compact length code A helps reduce mass, which supports quick start-stop cycles in small automation systems. Motion controllers receive rotor angle through absolute multi-turn feedback with more than 4096 revolutions, so position data remains available after power loss and multi-turn counts are restored at startup. The size code places the motor in a very small stator family intended for compact installations. A plain shaft with an integral shaft seal supports backlash-free clamping couplings and helps keep contaminants away from the bearings.
