The R911329202 (MSK071D-0300-NN-S3-UG0-NPNN) is a Bosch Rexroth IndraDyn S synchronous servomotor engineered for precise industrial motion applications. This model features a plain output shaft with sealing ring, operates with natural convection cooling, and has a flange assembly (B5) design. It provides a continuous torque of 20.0 Nm and a continuous current of 10.7 A (100 K). Maximum torque reaches 66.0 Nm, and maximum current is 40.5 A. The motor supports speeds up to 3,800 RPM and uses a singleturn optical encoder (Hiperface, capacitive, 16 signal periods, 240° rotatable connector) for accurate feedback. It is designed without a holding brake, has a D-length and size 071 frame, and incorporates a low-inertia rotor for rapid acceleration and deceleration. The unit weighs 18 kg, is rated IP65 for ingress protection, is built to insulation class 155°C, and features winding inductivity of 10,700 mH.

Frequently Asked Questions

How does winding inductivity influence current stability?

The higher inductance smooths the current profile under load changes. The motor then produces steadier torque output with less ripple.

Why is a flange mount preferred in compact layouts?

The flange style provides rigid alignment in standardized housings. The assembly reduces installation errors and improves repeatability.

How does encoder resolution impact motion control?

The finer signal periods allow better interpolation by the drive. The result is higher positional accuracy at varying speeds.

What is the benefit of not including a holding brake?

The absence of a brake lowers rotor inertia and improves dynamic response. The motor can accelerate and decelerate faster in cycle operations.

How does the rated speed code influence application selection?

The defined speed rating ensures optimal matching with load demands. The motor then avoids oversizing and maintains efficiency.
