The Bosch Rexroth R911381837 (MSK050C-0300-NN-S1-UP0-NSNN) is a synchronous servo motor from the MSK series, featuring a 050 frame size with C motor length. It delivers a continuous standstill current of 3.4 A and torque of 5.5 Nm at 100 K, with maximum ratings of 12.4 A current and 15.0 Nm torque. The motor uses a single-turn optical encoder with Hiperface interface, providing 128 signal periods/rotation and system accuracy of ±80 arcseconds. This model cools via natural convection and is designed without a holding brake. It includes a keyway shaft, standard/explosion-protected construction, rotatable 240° encoder connector, and an IP65 protection rating. The 2K epoxy resin (RAL9005) coating enhances chemical resistance. Winding inductivity is 45.1 mH.

Frequently Asked Questions

How does the MSK050C-0300-NN-S1-UP0-NSNN simplify encoder cable routing in constrained builds?

It includes a 240° rotatable encoder connector. This enhances cable orientation flexibility and reduces strain during tight-space installations.

Can this motor be deployed in hazardous or classified zones without design modifications?

It supports both standard and explosion protection. That enables integration into regulated environments without external enclosures or containment upgrades.

How does the MSK050C-0300-NN-S1-UP0-NSNN maintain position in dwell-based motion profiles?

It delivers 5.5 Nm continuous torque at standstill with 3.4 A. This ensures stable holding under long-duration static loads.

What encoder features support precise absolute tracking in high-speed singleturn applications?

It uses an optical encoder with Hiperface interface and 128 signal periods. This allows accurate angular resolution in real-time position feedback loops.

How does the shaft configuration improve torque transfer in precision mechanical assemblies?

The MSK050C servo motor uses a keyed shaft for positive engagement. It ensures slip-free operation under repeated acceleration and deceleration cycles.
