The R911328773 (MSK040B-0450-NN-M2-UG0-NNNN) is a Bosch Rexroth IndraDyn S synchronous servomotor featuring a standard plain shaft with a sealing ring and a winding code of 0450. It utilizes natural convection for cooling and should be cooled prior to servicing. The motor includes a 240° rotatable electrical connector and a backlash-free force-fit shaft hub. It supports axial forces up to 30N, has a black RAL 9005 housing, and incorporates an R-type concentricity and alignment tolerant optical encoder, EnDat2.1 interface, multiturn absolute type, and 2048 signal periods resolution. The unit operates with a maximum current of 6.0 A, continuous current at standstill of 1.7 A, and delivers a maximum torque of 5.1 Nm with 1.9 Nm continuous torque at standstill (100 K). The winding inductivity is 64,700 mH. Suitable for installations up to 1,000 m elevation and 5–95% relative humidity, it meets RoHS, CE, EAC, and cUL standards.

Frequently Asked Questions

How does the Bosch Rexroth Indramat MSK040B-0450-NN-M2-UG0-NNNN leverage its 2048-period EnDat2.1 encoder for ultra-fine positioning?

The high-resolution multiturn feedback captures exact shaft position over multiple revolutions, enabling sub-arcminute accuracy in coordinated motion systems.

Which benefit does the absence of a holding brake provide for applications with frequent acceleration and deceleration?

It reduces inertia on the shaft and eliminates brake wear, allowing faster start/stop cycles and smoother torque transitions under dynamic loads.

Where can the 64,700 mH winding inductivity improve performance most noticeably?

It dampens current ripple during high-speed moves, ensuring stable torque delivery from 1.9 Nm continuous to 5.1 Nm peak output.

Why is the Bosch Rexroth Indramat MSK040B-0450-NN-M2-UG0-NNNN especially suitable for sealed or low-noise installations?

Its natural convection cooling removes the need for fans, lowering noise and contamination risk while maintaining rated thermal conditions.

Under what maintenance practices can the EnDat2.1 encoder and connector maintain long-term signal integrity?

Routine inspection of the 240° rotatable connector and periodic cleaning around the encoder housing help preserve its 2048-period accuracy and feedback stability.
