The Bosch Rexroth synchronous motor R911326973 (MSK100B-0200-NN-S1-BG2-NNNN) from the IndraDyn S MSK series is engineered for precision drive control in industrial automation applications such as metalworking, packaging, and machine tools. It is built with Class 155 insulation and operates at temperatures of 60K and 100K. Main features include a natural convection cooling method, B-side power connector, singleturn Hiperface optical encoder with 128 signal periods, and an electrically-released holding brake rated at 70 Nm. The unit achieves a continuous torque of 33.0 Nm and continuous current of 17.3 A at 100K standstill, with peak values up to 102.0 Nm torque and 66.2 A current. The plain shaft, standard design, and low rotor inertia support rapid acceleration, while real-time position and speed feedback further optimize system responsiveness. Winding inductivity is specified at 7,600 mH.

Frequently Asked Questions

Why specify natural-convection cooling on MSK100B-0200-NN-S1-BG2-NNNN, and when consider add-on airflow or liquid options?

The natural convection simplifies cabling and maintenance for avoiding blower wiring in moderate duty cycles. It supports retrofit axial/radial fans or optional liquid cooling to extend continuous torque without exceeding winding temperature limits.

How does the 70 Nm electrically released holding brake benefit vertical or intermittent-motion axes?

It mechanically secures the load during e-stop or servo disable for reducing drift on Z-axes and indexers. Its brake enables safe maintenance positioning and faster restarts by holding tooling or web tension without drive current.

What are the key continuous/peak capabilities of MSK100B-0200-NN-S1-BG2-NNNN, and how do they translate to duty sizing?

It delivers 33 Nm of continuous torque and 102 Nm of peak torque while consuming 17.3 A and 66.2 A of rated current.

How does the B-side power connector orientation on MSK100B-0200-NN-S1-BG2-NNNN help machine layout?

Its B-side routing eases cable trays along machine frames and separates power from signal harnesses for improving EMC and service access. It also supports compact panel design around IndraDrive power stages.

What integration considerations apply when pairing MSK100B-0200-NN-S1-BG2-NNNN with Rexroth IndraDrive controllers?

The IndraDrive provides native Hiperface support, autotuning and safety options via IndraWorks engineering tools. Its parameter sets manage torque limits, thermal models and encoder diagnostics for rapid commissioning and lifecycle maintenance.
