The R911321785 (MSK100A-0200-NN-S1-BP0-NNNN) is an IndraDyn S synchronous servomotor from the Rexroth MSK series featuring natural convection cooling, a B-side power connector, and an optical Hiperface encoder providing 128 signal periods in singleturn mode. This unit supports a continuous current at standstill of 10.4 A, delivers 17.0 Nm continuous torque at standstill, and achieves up to 41.4 A maximum current and 54.0 Nm maximum torque, with a winding inductivity of 13,900 mH. It operates at a maximum speed of 4,400 RPM and includes a DIN 6885-1 compliant shaft with keyway and sealing ring. The housing, thermal class 155 and IP65 rated, has a sound pressure level of 61.1 dB[A] and a total mass of 23 kg. No holding brake is present.

Frequently Asked Questions

What does the IP65 construction of MSK100A-0200-NN-S1-BP0-NNNN practically enable on the factory floor?

The IP65 protects against dust ingress and water jets when connectors are correctly mated. It facilitates deployment near coolant spray, paper dust or packaging washdown zones without auxiliary enclosures.

Why is natural-convection cooling selected on MSK100A-0200-NN-S1-BP0-NNNN, and how does it impact duty planning?

The heat is rejected through the motor surface into ambient and the mounting structure for eliminating fan maintenance and airflow contamination.

How does a DIN 6885-1 keyed shaft on MSK100A-0200-NN-S1-BP0-NNNN affect torque transmission and hub selection?

The standardized key/keyway geometry provides repeatable shear capacity and prevents hub slippage under cyclic loads. It also simplifies coupling selection because hubs dimensioned to DIN 6885-1/ISO R773 align with common key widths and tolerances.

How should the 1.89 Nm/A torque constant for MSK100A-0200-NN-S1-BP0-NNNN guide current-loop tuning and inverter sizing?

It maps commanded phase current to electromagnetic torque at 20 °C to inform proportional gains and current limit thresholds. Its pairing with a drive whose continuous and peak currents comfortably exceed 10.4 A/41.4 A ensures thermal headroom and transient torque capability.

What does the ~75 dB(A) sound-pressure figure imply when MSK100A-0200-NN-S1-BP0-NNNN is mounted near operators?

This level helps maintain conversational audibility and supports acoustic compliance in packaging and assembly cells. It results from electromagnetic and mechanical balancing choices in the MSK family’s design envelope documented in series data.
