MKD025B-144-GP0-KN

The Bosch Rexroth Indramat MKD025B-144-GP0-KN servo motor is a high-performance member of the MKD Synchronous Motors series designed for precision motion control in industrial automation applications. This standard housing motor delivers reliable operation under varied conditions while maintaining robust ingress protection with an IP65 protection rating. Featuring permanent-magnet construction and electronic commutation, the MKD025B-144-GP0-KN excels in providing stable dynamic response and high overload capability with minimal maintenance requirements. Resolver-based encoder feedback further enhances positional accuracy, making this motor suitable for demanding machine tool, packaging, and handling systems.

Technical specifications are engineered to exacting standards for performance and integration. The motor’s motor size of 025 corresponds to a compact footprint with a center diameter of 40 mm and a flange size of 54 mm. It incorporates a shaft with keyway design and an effective shaft seal for enhanced ingress protection. The housing design is classified as standard and painted black, featuring a connection box for secure power and feedback cable attachment in the side B connection direction. The winding code 144 supports convection cooling and thermal management, with a thermal time constant of 15 minutes and an operating ambient range of 0 to 45°C. Insulation class F is specified to ensure electrical durability under elevated temperature conditions.

Operational performance is characterized by a continuous torque at standstill of 0.9 Nm and a continuous current draw of 5.1 A. The motor sustains a rated speed of 5000 RPM and can reach up to maximum speed of 9000 RPM for high-speed duties. Theoretical peak torque stands at 4 Nm, enabling rapid acceleration and precise load handling. The relative position detection via resolver feedback (RSF) provides closed-loop control with minimal drift, while the absence of a holding brake simplifies mechanical interfaces where external braking options are preferred. With a mass of 2 kg and low-inertia design, the MKD025B-144-GP0-KN delivers excellent power-to-weight ratio for agile motion sequences.

System integration is streamlined through compatibility with standard servo drives and control platforms from Bosch Rexroth Indramat. The resolver encoder interface supports direct connection to multi-axis controllers, eliminating the need for separate homing procedures. Targeted applications include CNC machining centers, automated packaging lines, pick-and-place systems, and robotics where high reliability, precise feedback, and robust environmental protection are critical to achieving continuous production throughput.
