Product Description:
The MKD025B-144-KP1-KS is a servo motor manufactured by Bosch Rexroth Indramat within the MKD Synchronous Motors series. In automated cells, it supplies closed-loop rotary motion to indexing tables, small pick-and-place arms, and auxiliary axes where compact dimensions and stable holding are required. An integrated holding brake and resolver-based feedback let the connected drive controller keep vertical or suspended loads in position when main power is removed.
At standstill, the motor delivers 0.9 Nm of continuous torque, which is suitable for light loads that prioritize accuracy. Dimensional references include a centering diameter of 40 mm and a 54 mm square flange that aligns with gearheads and machine frames. The housing has an IP65 rating, so dust is kept out and water jets do not interfere with operation. Position feedback is provided by resolver feedback integrated behind the shaft, giving analog sine-cosine signals that resist electrical noise; absolute interpolation beyond 4096 revolutions is handled by the drive electronics. Power and feedback conductors terminate in a sealed connection box on side B of the stator, keeping cables inside the machine envelope.
Beyond its base torque rating, the integrated brake provides 1 Nm of holding torque, preventing drift when the axis is idle. Motion accuracy is supported by a cumulative system tolerance of ±8 angular minutes, and the keyed shaft helps secure couplings during operation. The motor is intended for ambient temperatures from 0–40 °C and uses Class F insulation on the windings. In size 025 with length B, the rotor has low inertia, and winding code 144 identifies the electrical characteristics used with matching Rexroth drives. A positive shaft seal protects the front bearing from coolant spray, and the side-B connection box keeps cable access concentrated at one end.
