The Bosch Rexroth MPN R911331295 (MSK040B-0450-NN-M2-UG1-NNNN) is an IndraDyn S synchronous servomotor intended for environments protected from direct light, salt mist, ice, and condensation. Featuring natural convection cooling, a plain shaft, and size 040, length B frame, it integrates an EnDat 2.1 multiturn absolute optical encoder with 2,048 signal periods and ±20 angular seconds system accuracy. Encoder connectors are rotatable to 240 degrees. The motor delivers 1.9 Nm continuous torque at standstill (100 K), with a maximum of 5.1 Nm, and continuous current at standstill of 1.7 A (100 K), maximum current 6.0 A. It incorporates an electrically-released holding brake with 4 Nm torque, operates below 75 dBA, is built to thermal class 155 per EN 60034-1, and includes IP67 rated connectors and a chemical and oil-resistant shaft sealing ring. The winding code is 0450, and the winding inductivity is 64,700 mH.

Frequently Asked Questions

Through what mechanism does the EnDat2.1 feedback enhance axis coordination during synchronized motion?

The digital encoder transmits absolute position data in real time, allowing precise phase alignment between multiple drives without signal drift.

Under which duty profiles can the 4 Nm brake provide dependable load retention without overcycling?

In vertical-axis and holding applications, it engages only at standstill, minimizing wear while maintaining secure mechanical locking during shutdowns.

Why is the Bosch Rexroth Indramat MSK040B-0450-NN-M2-UG1-NNNN often selected for robotics requiring low-inertia response?

Its compact rotor design and 64,700 mH inductance deliver rapid current control, allowing precise motion starts and stops with minimal overshoot.

In what ways does natural convection cooling contribute to long-term efficiency in enclosed automation cells?

By eliminating forced airflow, it prevents dust intake and mechanical vibration, supporting quiet, maintenance-free thermal management over continuous duty.

To what extent can maintenance routines extend the Bosch Rexroth Indramat MSK040B-0450-NN-M2-UG1-NNNN’s encoder accuracy and mechanical reliability?

Regular inspection of connector torque, brake clearance, and encoder sealing helps preserve deterministic feedback and sustained torque precision.
