The Rexroth synchronous servo motor, MPN R911323740 (MSK050C-0450-NN-S1-UP1-NNNN), is engineered for industrial automation tasks requiring precise position and speed control. It features a shaft with keyway, standard design, and utilizes natural convection cooling. The motor offers a maximum torque of 15.0 Nm and maximum current of 18.8 A, with continuous torque at standstill (100 K) rated at 5.5 Nm and a continuous current at 5.2 A. The integrated optical singleturn encoder (Hiperface, 128 signal periods) supports accurate feedback. Motor size is 050 with length C, and the rotatable encoder connector allows 240° adjustment. The unit lacks holding brakes but includes an electrically-released holding brake providing 6 Nm torque. Winding inductivity is 20,200 mH. The enclosure is rated IP65, thermal class 155 (EN 60034), and specified for operation from 0 to 40°C.

Frequently Asked Questions

How does the encoder interface support installation in tight industrial layouts?

It features a 240° rotatable connector. This allows flexible cable positioning and reduces stress during confined cabinet routing.

What feedback configuration is used for high-speed singleturn positioning tasks?

It uses an optical singleturn encoder with Hiperface interface. This enables reliable position tracking with integrated digital communication.

How does the MSK050C-0450-NN-S1-UP1-NNNN manage torque stability under static load at elevated temperature?

It delivers 5.5 Nm continuous torque at standstill. This supports thermal consistency in dwell-heavy applications.

What inductive property stabilizes current delivery under rapid motion transitions?

It features a 20,200 mH winding inductivity. This smooths current response and reduces torque ripple in dynamic load profiles.

How does the MSK050C-0450-NN-S1-UP1-NNNN ensure safe shaft retention during uncontrolled power-down scenarios?

It includes a 6 Nm electrically released holding brake. This secures the shaft mechanically in powered-off or emergency stop conditions.
