MKD025B-144-GG0-KN

The Bosch Rexroth Indramat MKD025B-144-GG0-KN is a high-performance MKD Synchronous Motors series servo motor designed for demanding automation systems. Weighing 2.9 kg with a plain shaft and integrated shaft seal, this compact unit delivers robust dynamics in a small footprint. Its protection to IP65 rating and natural convection cooling ensure reliable operation in dusty or mildly wet environments without the need for forced ventilation. This motor is optimized for integration with Bosch Rexroth drive controllers, forming part of proven Ecodrive or Diax04 solutions for precision motion control. The absence of a holding brake reduces complexity, while the single-turn resolver feedback supports relative position detection for streamlined homing routines.

Technical specifications for the MKD025B-144-GG0-KN are comprehensive and precise. It operates at a rated voltage of 326 V and draws a rated current of 9.3 A, achieving a maximum speed of 8000 RPM and delivering a continuous torque at standstill of 0.9 Nm. The motor’s rotor inertia is 0.0006 kg·m², supporting rapid acceleration and deceleration. Feedback is provided by a resolver feedback (RSF) encoder with position detection set to relative mode. The device carries a winding code of 144, a flange diameter corresponding to a motor size of 025, and a motor length designated B. Power and signal connections exit via Connection Direction on Side B, simplifying cable routing in confined installations.

Operational features emphasize durability and stable performance. The unit’s Protection Class of IP65 shields internal components from dust and light spray, while a shaft sealing ring prevents ingress into the bearing area. Without a holding brake, the motor relies on controlled deceleration routines within accompanying drives. Its storage temperature range from –20 °C to +80 °C and natural convection cooling allow flexible placement without additional heat exchangers. Continuous operation at full load remains within specified thermal limits, and the resolver feedback ensures consistent position tracking over long service intervals.

System integration is straightforward when paired with Bosch Rexroth DKC drives, enabling advanced motion control functions such as electronic gearing, cam profiling, and error compensation. The MKD025B-144-GG0-KN’s compatibility with Ecodrive and Diax04 platforms makes it suitable for precision packaging, assembly robotics, and CNC applications. Its compact form factor and robust IP65 protection render it ideal for food and beverage machinery with washdown requirements. Overall, this motor provides a balanced combination of performance, reliability, and ease of integration for modern automated production lines.
