The REXROTH MKD025B-144-KP0-UN is a model in Bosch Rexroth’s Indramat MKD series of digital AC synchronous servo motors. This particular motor features a 025 frame size with a “B” length construction delivering robust continuous torque. Its built-in resolver feedback combined with an integrated multiturn absolute encoder ensures high positional accuracy and reliable feedback even under challenging operating conditions. The motor shaft is a plain type with a key according to DIN 6885-1 standards, designed for secure mounting and mechanical coupling in automation machinery. With a nominal speed of approximately 3,000 revolutions per minute and rated current around 6.0 A, this motor is engineered for precision servo drive applications. The MKD025B-144-KP0-UN fits naturally within Rexroth’s servo drive ecosystem, enabling easy system integration and efficient control for dynamic industrial automation solutions.

Technically, the REXROTH MKD025B-144-KP0-UN offers a continuous torque of roughly 0.9 Nm and supports peak torque values to handle transient load conditions effectively. The motor maintains high efficiency thanks to its synchronous design, ensuring tight speed and torque regulation for applications requiring consistent output performance. The closed motor design gives the unit IP65 protection, which guards against dust and water ingress, extending motor life in demanding manufacturing environments. Thermal management is achieved through natural convection cooling without requiring forced ventilation, simplifying installation and maintenance. The resolver feedback system paired with an absolute multiturn encoder provides robust positioning data, essential for closed-loop servo control systems. With its compact dimensions and flange mounting, the motor is ready for straightforward mechanical installation and coupling, making it a reliable and durable element in multi-axis motion systems and precision automation tasks.

Compatible modules include the DKC10.3-018-3-MGP-01VRS servo drive, which optimally controls this motor within advanced motion systems. The IndraMotion MLC controller coordinates multi-axis control and performs high-level motion logic. Related servo motors like the MKD025B-144-KG0-UN offer variations in feedback and shaft configurations to match application-specific demands. For enhanced safety integration, Rexroth’s IndraDrive safety modules complement the motor’s operation. Feedback upgrades like high-resolution encoders add precision and system responsiveness.

When installing the MKD025B-144-KP0-UN, ensure adequate ventilation in the control cabinet to maximize the motor’s natural convection cooling efficiency. Proper grounding and cable routing prevent electromagnetic interference from compromising feedback signals. The flange mount should be securely fastened to minimize vibration and maintain mechanical stability. Routine inspections focusing on wiring integrity and thermal conditions are advised to preempt operational issues. Regular access to diagnostics and updates through compatible servo drives facilitates predictive maintenance and helps maintain peak performance.
