The motor’s design offers a balanced combination of compact size and power output, making it ideal for equipment setups that require a medium frame motor delivering robust functionality without sacrificing installation flexibility. Its capabilities make it applicable in control systems where accurate positioning and speed synchronization are critical for maintaining productivity and quality during complex operational cycles.

The REXROTH MKD071B-061-KG1-KN belongs to the Bosch Rexroth MKD series of digital AC synchronous servo motors, engineered for precision motion control applications. It serves as a crucial actuator in automated systems, converting electrical energy into precisely controlled mechanical motion. This model’s stack size 071 reflects its medium-sized magnetic core, delivering a torque peak of up to 18 Nm. Feedback is a key feature, utilizing resolver technology combined with an integrated multiturn absolute encoder, ensuring excellent positional accuracy and reliable tracking even after power interruptions. The plain shaft design allows for straightforward mechanical integration with couplings and gearboxes, essential in industrial automation setups. This motor is typically paired with Rexroth servo drives for seamless communication and efficient performance, making it valuable for engineers designing multi-axis servo systems or precision machinery.

The REXROTH MKD071B-061-KG1-KN offers several important technical benefits. Its peak torque of 18 Nm supports high dynamic load handling, while a rated speed of 6,000 rpm offers balanced performance for medium-speed applications. The resolver feedback system enables robust motor position sensing even in electrically noisy industrial environments, contributing to reliable closed-loop control. The integrated multiturn absolute encoder preserves position data across power cycles, minimizing downtime caused by rehoming. Built with a plain shaft and flange mounting, the motor’s hardware is designed for ease of mechanical installation and secure torque transmission. The motor’s natural convection cooling supports long service life by maintaining thermal stability without requiring additional cooling components. The combination of these attributes makes the motor reliable in challenging applications such as robotic arms, printing presses, and packaging machines that require accurate and repeatable movements.

Complementary products for the MKD071B-061-KG1-KN include the DKC10.3-018-3-MGP-01VRS servo drive, specifically designed to manage this motor’s performance in sophisticated motion control setups. The IndraMotion MLC motion controller offers advanced programmable logic coordination for multi-axis systems. Rexroth’s resolver feedback modules enhance positional accuracy when paired with the motor. The holding brake unit option provides mechanical braking capacity for increased safety. Additionally, the IndraDrive Safety Modules integrate functional safety features compatible with the MKD motor line.

Installing the REXROTH MKD071B-061-KG1-KN requires attention to cabinet ventilation to leverage its natural convection cooling effectively and avoid overheating. Adequate grounding is necessary to minimize electrical noise and ensure stable feedback signals. The motor’s flange mount should be secured firmly, providing stability and limiting vibration that could impact performance or longevity. During operation, routine inspection of connectors and motor temperature is recommended, alongside utilizing diagnostic feedback from the servo drive for predictive maintenance. Firmware and parameter updates should be performed following Bosch Rexroth’s guidelines to maintain optimal motor control and reliability.
