The R911339484 (MSK040B-0450-NN-M1-UG0-NSNN) is an IndraDyn S synchronous servomotor designed for demanding industrial applications. It operates at AC 3 × 400–480 V, with a continuous current at standstill of 1.7 A (100 K) and continuous torque at 1.9 Nm (100 K). The unit supports a maximum current of 6.0 A and delivers up to 5.1 Nm peak torque, achieving speeds up to 6000 rpm. The motor features natural convection cooling, a plain shaft, B05 (IMB5/IMV1/IMV3) configuration, and an IP65 rated enclosure. It employs a multiturn absolute optical Hiperface encoder with 128 signal periods and a rotatable 240° connector, without a holding brake. Winding inductivity is specified at 64,700 mH. Operating temperature range is 0 to +40 °C. ATEX compliance for explosion protection is included.

Frequently Asked Questions

How does the Bosch Rexroth Indramat MSK040B-0450-NN-M1-UG0-NSNN achieve precision without relying on a holding brake?

Its optical multiturn encoder with 128 signal periods continuously tracks shaft position, maintaining micro-level accuracy even during free-motion deceleration.

What makes its 64,700 mH winding inductivity beneficial in high-acceleration conveyor or packaging systems?

The high inductance smooths current spikes and ensures torque linearity, reducing overshoot when accelerating or stopping under fluctuating loads.

In which type of environments does the explosion-protection variant of this motor provide added reliability?

It safeguards motion systems in hazardous areas where airborne particles or vapors demand certified spark-resistant construction.

Why is the Bosch Rexroth Indramat MSK040B-0450-NN-M1-UG0-NSNN ideal for fanless enclosures or sealed control cabinets?

Natural convection cooling eliminates fan dependency, maintaining stable thermal profiles in compact or contamination-sensitive systems.

Which maintenance practices ensure long-term encoder accuracy and stable mechanical performance?

Periodic connector inspections and cleaning of the optical encoder’s housing protect against dust buildup, preserving resolution integrity and signal reliability.
