The R911333157 (MSK071D-0300-NN-M2-UG2-RNNN) is a Rexroth IndraDyn S synchronous servomotor belonging to the MSK series. It features natural convection cooling, a plain shaft, and a D-length 071-size design. The integrated EnDat 2.1 optical encoder provides multiturn absolute feedback with 2048 signal periods and system accuracy of ±20 angular seconds, supporting up to 4096 mechanical rotations. The motor delivers up to 20.0 Nm continuous torque and 66.0 Nm maximum torque, with a standstill current of 10.7 A (100 K) and a maximum current of 40.5 A. The winding inductivity is 10,700 mH. It incorporates a 30 Nm electrically-released holding brake with a connection time of 35 ms, increased concentricity, and rotatable encoder connection (240°). The housing is finished in black RAL9005 2K epoxy resin and rated IP65 for dust and water spray protection, suitable for use in environments with exposure to mineral oils, dilute acids, alkalis, and sewage.

Frequently Asked Questions

How does natural convection cooling impact the motor performance in continuous operation?

The cooling method allows heat to dissipate without forced airflow. The motor can therefore operate in quieter environments but may need additional cooling in high duty cycles.

What advantage does an electrically released holding brake provide in industrial use?

The brake ensures the shaft remains locked when power is off. The feature increases safety in vertical axis applications and prevents load drops during power loss.

How does the multiturn absolute encoder enhance positioning accuracy?

The encoder tracks shaft position over multiple revolutions without resetting. The system ensures precise feedback for automation processes that require high accuracy.

How does motor weight influence installation and system design?

The mass adds stability in mounting but may require strong support frames. The weight must be factored into axis load calculations for system reliability.

What benefit does a plain shaft design bring to integration?

The design simplifies coupling with external gearboxes and couplings. The motor offers flexibility in different mechanical setups without complex adapters.
