MSK071D-0300-NN-M1-UG1-NN04

The MSK071D-0300-NN-M1-UG1-NN04 from Bosch Rexroth Indramat is an advanced IndraDyn S Synchronous Servomotor in the MSK IndraDyn S Synchronous Motors series, offering a precise and reliable solution for demanding automation tasks. This Product Type features a compact Motor Size of 071 and a standardized Motor Length designation of D, ensuring compatibility with existing drive systems. Equipped with a robust Winding Code of 0300, this motor delivers consistent performance across a broad speed range. An integrated Holding Brake that is electrically released provides a Holding Brake Torque of 23 Nm, securing the load in stationary conditions. With a mass of 19.6 kg and a plain Shaft Type, the unit balances structural integrity with ease of installation.

The MSK071D's electrical and mechanical characteristics are engineered for high dynamic response and efficiency. At a reference temperature of 100 K, the motor sustains a Continuous Current at Standstill 100 K of 8.6 A and a Continuous Torque at Standstill 100 K of 20.0 Nm. It supports a Maximum Current rating of 40.5 A and achieves a peak Maximum Torque of 66.0 Nm, catering to short-term overload requirements. The Winding Inductivity of 10,700 mH and optimized magnetic circuit minimize electrical losses, while the motor’s Cooling method of natural convection eliminates the need for auxiliary cooling devices. Feedback and position accuracy are ensured by an Encoder Technology based on optical sensors, offering Encoder Resolution of 128 signal periods, a Multiturn Absolute Encoder Turn Type, and a Hiperface Encoder Interface. Its Rotatable, 240° Encoder Connector simplifies routing and reduces cabling constraints.

Operational reliability is reinforced by the motor’s plain shaft configuration and balanced rotor design, which reduce vibration and extend bearing life under continuous operation. The inherent thermal stability of the Natural convection cooling strategy and robust construction support long service intervals and low maintenance costs. Its electrically released Holding Brake allows for secure load retention during power interruptions, facilitating safe shutdowns and restart procedures. Precision-engineered winding and encoder systems ensure repeatable start-stop cycles and high positional accuracy for multi-axis coordination. The assembly’s brushless topology and high inductivity windings contribute to smooth acceleration profiles and minimal torque ripple.

Integration into motion control architectures is straightforward, as the MSK071D series seamlessly interfaces with Bosch Rexroth’s IndraDrive controllers and standard fieldbus networks. The motor’s standard mounting dimensions and plain shaft interface allow direct replacement in legacy installations or incorporation into new designs. Its comprehensive feedback suite and standardized electrical characteristics facilitate plug-and-play configuration through Rexroth’s software tools, reducing commissioning time. Ideal for applications in robotics, packaging machinery, CNC systems, and automated assembly lines, the MSK071D-0300-NN-M1-UG1-NN04 combines high torque density, reliable braking, and precise encoder feedback for optimized performance in demanding industrial environments.
