Product Description:

The MKD025A-144-KP0-UN is a compact servo motor produced by Bosch Rexroth Indramat for the MKD Synchronous Motors series. As a brushless AC unit, it drives light-duty axes, pick-and-place heads, or small rotary tables where precise closed-loop motion is required. In a typical automation cell, it couples with a digital drive controller, translating commanded current into rotational displacement so that tooling or sensors can be positioned quickly and repeatably within their programmed envelope.

Mechanically, the motor mounts to a machine plate through a 54 mm flange size, and its shaft is referenced to tooling by a 40 mm centering diameter that ensures consistent concentricity. Electrical and feedback plugs may be oriented anywhere within a 270° connection direction window, simplifying cable routing inside crowded enclosures. Under stall conditions, the rotor delivers 0.4 Nm of continuous torque at standstill, enough to drive small loads without overheating when paired with the 144 winding code. A sealed housing rated IP65 blocks dust and low-pressure water jets, so the unit can be installed near coolant spray or material fines. Power and encoder connectors share a common side exit, reducing panel depth and matching standard MKD harnesses.

Thermally, F-class windings tolerate up to 155 °C, and this reserve is reflected by the F insulation class, helping the stator withstand duty cycles that swing from idle to peak current. Resolver electronics supply multi-turn position data with absolute (>4096 revs) position detection, and the control loop can hold accuracy within ±8 angular minutes, meeting the demands of indexing tables or vision-guided actuators. Operation is permitted over a 0–40 °C ambient temperature range, and a factory-installed shaft seal prevents lubricant egress along the keyed shaft. The KP0 variant is built without a holding brake, uses motor length A and size 025, and provides separate power and encoder connectors for straightforward setup.
