MSK071C-0450-NN-M2-UG0-RNNN
MSK IndraDyn S Synchronous Motors
MSK071C-0450-NN-M2-UG0-RNNN, Bosch Rexroth Indramat, MSK IndraDyn S Synchronous Motors deliver precision motion control in a compact servomotor package. Featuring a Motor Size of 071 and a Motor Length code of C, this Product Type is engineered for high-dynamic applications. The design emphasizes Increased concentricity to minimize runout and vibration, while the Shaft Type of plain shaft ensures straightforward coupling. With a rated speed code of 0450, the motor seamlessly integrates into multi-axis systems requiring consistent performance.
In-depth technical specifications include a continuous torque at standstill (100 K) of 14.0 Nm and a continuous current at standstill (100 K) of 10.4 A, supporting sustained holding applications. Peak capabilities rise to a Maximum Torque of 44.0 Nm at a Maximum Current of 40.1 A, driven by a winding inductivity of 6,700 mH for smooth current shaping. The motor operates without a brake (Holding Brake: Without holding brake), relying on precise electronic control. Cooling is managed by Natural convection, eliminating the need for forced-air systems. Motion feedback is provided by an Optical Encoder Technology using a Multiturn Absolute Encoder Turn Type, with 2048 signal periods resolution via an EnDat2.1 Encoder Interface and a rotatable Encoder Connector offering 240° orientation flexibility.
Integration is streamlined through the EnDat2.1 interface, facilitating high-speed, bidirectional communication with Rexroth IndraDrive controllers. The motor’s robust Increased concentricity design and Natural convection cooling deliver reliable operation in varied industrial environments. Its compact 071 frame and plain shaft simplify mounting, making the MSK071C-0450-NN-M2-UG0-RNNN ideal for robotics, packaging machines, and CNC applications where precision, repeatability, and low maintenance are paramount.

Frequently Asked Questions
What does the “increased concentricity” design contribute in multi-axis contouring or gantry applications?
The elevated shaft/hub concentricity reduces radial runout, cutting interpolation error and torque ripple at low speed. It results in smoother motion for helping tight contour tolerances and better surface finish in coordinated axes.
How does the 6,700 mH winding inductivity of MSK071C-0450-NN-M2-UG0-RNNN influence current quality and loop tuning?
The higher inductivity filters current ripple from the drive PWM for yielding smoother torque production. It also widens stability margins for current/velocity loops that often allows slightly higher controller gains without audible chatter.
Is the plain shaft on MSK071C-0450-NN-M2-UG0-RNNN suitable for direct couplings or belt transmissions, and what should be considered?
Yes, use precision bellows or elastomer couplings for low-runout connections or correctly sized pulleys if using belts. It is also important to validate radial/axial load limits and apply proper keying/clamping per Rexroth recommendations.
Can the EnDat 2.1 feedback on MSK071C-0450-NN-M2-UG0-RNNN integrate natively with Rexroth IndraDrive controllers?
The IndraDyn S MSK motors are designed for the IndraDrive ecosystem. Its EnDat feedback is a commonly supported interface for Rexroth digital drives for enabling fast, bidirectional setup and diagnostics via motor databank.
What protection and option breadth characterize the MSK series relevant to specifying MSK071C-0450-NN-M2-UG0-RNNN?
The IP65-class housings, multiple cooling concepts and diverse encoder systems enables adaptation to varied environments and controls. Its traits eases drop-in standardization across machine families.
