The R911312443 (MSK076C-0300-NN-S2-UP0-RNNN) is a Rexroth IndraDyn S synchronous servomotor designed for applications requiring high torque density, precise control, and consistent performance in demanding conditions. It utilizes an optical singleturn encoder (EnDat2.1) with 2048 signal periods and a rotatable 240° connector. The servomotor achieves a maximum speed of 4700 min⁻¹, maximum torque of 43.5 Nm, and a continuous torque at standstill of 13.5 Nm at 100 K, with a continuous current of 8.1 A and maximum current of 32.4 A. The device has a shaft with keyway, increased concentricity, winding inductivity of 12,600 mH, and a moment of inertia of 0.00430 kg·m². Cooling is accomplished by natural convection and conduction to the machine. This model is provided without a holding brake. Adherence to all relevant safety protocols is required during installation and operation.

Frequently Asked Questions

How does the optical singleturn (2048 periods) encoder with EnDat 2.1 enhance positioning accuracy on MSK076C-0300-NN-S2-UP0-RNNN?

It delivers fine interpolated position data and stable digital transmission for reducing analog noise paths. Its EnDat enables parameter readout and diagnostics for tighter servo loops and rapid commissioning in digital drive systems.

Why does the “increased concentricity” design matter for this motor’s mechanics?

Its improved concentricity reduces shaft runout and unbalance for lowering vibration, bearing loads and velocity ripple. It translates into better contour accuracy and smoother current/torque utilization in high-bandwidth motion loops.

How does natural-convection cooling on MSK076C-0300-NN-S2-UP0-RNNN affect duty and scaling?

It’s ideal when continuous losses are moderate and airflow is available around the frame. The MSK family also supports retrofit blower or liquid cooling options when higher continuous power density is required.

What advantage does the shaft with keyway offer for MSK076C-0300-NN-S2-UP0-RNNN couplings?

The keyed interface provides positive drive and repeatable torque transmission for minimizing micro-slip under dynamic reversals. It simplifies hub selection for timing pulleys, gearheads or bellows couplings in cyclic axes.

What role does the 12,600 mH winding inductivity play in control stability?

The higher phase inductivity attenuates current ripple and shapes the electrical time constant for easing current-loop tuning. It supports smoother torque transitions during step loads and reduces amplification of bus ripple into mechanical motion.
