MKD071B-024-GG1-KN

The Bosch Rexroth Indramat MKD071B-024-GG1-KN is a high-performance servomotor in the MKD Synchronous Motors series, designed for precision industrial applications. This surface-cooled digital AC motor delivers a maximum speed of 3500 RPM and a nominal voltage of 300 V DC to meet demanding motion control requirements. With an integrated resolver feedback system, it ensures accurate position detection and reliable communication with Indramat digital intelligent drive controllers. The robust design includes IP65 protection and standardized angular connectors, enabling maintenance-free operation in harsh environments. Continuous torque at standstill is rated at 8.0 Nm, providing stable holding capacity for vertical or suspended loads.

Technical specifications are comprehensively defined for precise system integration. The motor features a plain shaft equipped with a shaft sealing ring and an end-sided centering hole (thread “DS”), complying with the Shaft Design and Shaft Seal requirements. It includes a holding brake with a brake torque of 5 Nm for immediate load retention, and resolver feedback (RSF) as the Encoder Type for relative position detection. The winding code is 024, with a winding resistance of 8.4 Ω and inductance of 34.4 mH, supporting a rated frequency of 100 Hz. Additional dimensions include a flange diameter of 115 mm and a motor length designation of B, resulting in an overall weight of approximately 8.5 kg.

Operational features emphasize reliability and performance under variable conditions. Surface cooling maintains thermal stability, while the protection category of IP65 and relative humidity tolerance up to 95% non-condensing ensure operation in challenging environments. The moment of inertia of 0.0009 kg·m^2 enables rapid acceleration and deceleration cycles, and the peak current capacity of 19.8 A supports short-term overloads. Continuous torque is rated at 9 Nm, with a maximum torque of 24 Nm at standstill for demanding startup scenarios. Transport and storage tolerances range from -20 to 80 °C, safeguarding the unit during handling and seasonal extremes.

System integration is streamlined through a connection box interface that accommodates both power and feedback cables, reducing installation complexity and cable routing. Compatibility with Indramat digital intelligent drive controllers allows for advanced functions such as auto-tuning, overload protection, and diagnostic feedback. The motor’s standardized design and resolver feedback eliminate the need for external sensors, enhancing system reliability. Ideal applications include printing and paper machinery, food processing equipment, and automated assembly lines where precision, robustness, and easy maintenance are critical.
