The R911332295 (MSK071C-0450-NN-M2-UP0-RNNN) is an IndraDyn S Synchronous Servomotor designed by Rexroth Indramat. This motor features a brushless construction with a compact housing, generating a continuous torque of 14.0 Nm at a standstill (100 K) with a current of 10.4 A. Maximum torque output is 44.0 Nm at a maximum current of 40.1 A, with peak rotational speed reaching 5800 RPM. The shaft employs a keyway and motor length is specified as size C with motor size 071. Position feedback is facilitated by a multiturn absolute optical encoder (EnDat2.1 interface), supporting 2048 signal periods, and the encoder connector is rotatable by 240°. The design excludes a holding brake and prioritizes increased concentricity. The system uses natural convection for cooling, features a winding inductivity of 6.7 mH, a torque constant of 1.49 Nm/A, voltage constant of 91.3 V/min at 20°C, and a discharge capacity of 4.2 nF. The unit weighs 13.9 kg with a thermal time constant of approximately 15 minutes.

Frequently Asked Questions

What commissioning advantages come from the 240° rotatable power and encoder connectors?

The angled, rotatable interfaces simplify cable routing in cramped cabinets and gantries for reducing bending stress and EMI coupling. Its faster dress-pack integration shortens installation time and eases service access during retrofits.

Why specify the shaft-with-keyway variant for MSK071C-0450-NN-M2-UP0-RNNN?

The keyed shaft resists slip under frequent reversals and high start/stop torsion for improving coupling reliability. It’s a practical pick for belt, pulley and low-backlash gearbox interfaces in high-throughput lines.

How do the electrical ratings of MSK071C-0450-NN-M2-UP0-RNNN affect servo sizing?

The 10.4 A continuous at standstill and 40.1 A peak, the drive must supply adequate current headroom for acceleration and jerk limits. It is important to check DC bus voltage and cable sizing to avoid voltage sag.

What encoder protocol details matter when pairing this motor with third-party controllers?

Its EnDat 2.1 serial interface provides bidirectional data and diagnostics. Its proper termination and cable shielding preserve 2048-period signal integrity at speed.

How do mechanical loads impact bearing life in the MSK071 size class?

The axial/radial load curves and L10h duty-cycle mean speeds is important to consider. Its bearings are rated around 30,000 hours when within limits and its proper alignment/lubrication of couplings protects the front seal and bearings

Internal Product Review

The IndraDyn S series servomotor MSK071C-0450-NN-M2-UP0-RNNN from Indramat possess nearly 6.7 mH of winding inductance and delivers 14 Nm stall torque along with 44 Nm of peak torque. It depends on natural-convection and includes an EnDat 2.1 multiturn encoder through a rotatable 240° connectors for speed commissioning. This unit is accompanied by a balance shaft of keyway design for easy coupling with system in machine tools and pick-and-place robotics.
