The R911338404 (MSK071C-0450-NN-M2-UG0-RNNN) is an IndraDyn S synchronous servomotor engineered for industrial applications requiring precise control and energy conversion. It features a size 071, length C design with a plain shaft and increased concentricity. The motor utilizes natural convection for cooling and operates with an optical multiturn absolute encoder (EnDat2.1 interface, 2048 signal periods, 240° rotatable connector). Electrical specifications include a continuous standstill current of 10.4 A (100 K), continuous standstill torque of 14.0 Nm (100 K), maximum current of 40.1 A, and maximum torque of 44.0 Nm. Winding inductivity is 6,700 mH. The housing is protected with a black coating resistant to acids, alkalis, lyes, and hydraulic oils. The design supports high-frequency start-stop operation up to 44 °C.

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.
