The Bosch Rexroth R911322619 (MSK100B-0450-NN-S1-AP1-NNNN) is an MSK series synchronous servomotor designed for precise speed coordination with the input frequency. It incorporates an optical single-turn encoder with Hiperface interface and 128 signal periods, and accommodates both single-turn and multi-turn encoders. The motor supports natural convection and surface cooling, delivering an output torque of 28 Nm (natural convection) and up to 42 Nm (surface cooling), with a maximum speed of 4500 RPM. Technical specifications include a moment of inertia of 0.01920 kg·m², a maximum torque of 102.0 Nm, a maximum current of 110.7 A, continuous current at standstill 33.6 A, continuous torque at standstill 33.0 Nm, winding inductivity of 2,200 mH, and an optional electrically released holding brake rated at 32 Nm. It has an IP65 protection rating, standard housing, a size 100B frame, a keyway shaft, and A-side power connector.

Frequently Asked Questions

What standstill torque characterizes retention on the MSK100B-0450-NN-S1-AP1-NNNN?

Sustained 33.0 Nm counters back-drive, enabling accurate gauging, bonding or assembly dwell steps that demand negligible positional deviation over time.

How much peak current supports acceleration on the MSK100B-0450-NN-S1-AP1-NNNN?

Allowing 110.7 A momentarily provides energetic starts, cutting approach duration before high-precision control completes the move at tight tolerance.

How does inductivity condition current on the MSK100B-0450-NN-S1-AP1-NNNN?

At 2,200 mH, current ramps stay smooth, improving torque linearity and minimizing ripple visible to high-gain position loops.

How does encoder scaling assist commissioning on the MSK100B-0450-NN-S1-AP1-NNNN?

Singleturn Hiperface publishes 128 signal periods per revolution, providing absolute angle data for immediate loop closure after resets, eliminating re-homing overhead and tightening startup repeatability.

Which continuous current value frames thermal planning for the MSK100B-0450-NN-S1-AP1-NNNN?

Operating at 33.6 A continuously maintains temperature discipline and consistent torque authority during prolonged hold conditions and slow-speed positioning routines.

Internal Product Review

Indramat's MSK100B-0450-NN-S1-AP1-NNNN is a must-have model as it simply favors shafts with keyway engagement to ensure positive torque transfer under reversals. That interface maintains angular registration, simplifies coupling selection and supports predictable timing in A-side routed, fanless cabinets.
