The Bosch Rexroth R911327295 (MSK100A-0300-NN-S1-AP0-NNNN) is a synchronous servomotor featuring an internal temperature sensor and absolute single-turn Hiperface optical encoder with 128 signal periods. It is rated for optimal operation between -20°C and +80°C and provides a thermal time constant of 39 minutes. With natural convection cooling and an inertia moment of 0.01100 kgm², the 23 kg unit delivers 22.5 Nm torque at 15.3 A during surface cooling and achieves a rated continuous torque of 17 Nm at 100K and 15 Nm at 60K, with continuous current at standstill of 11.6 A and maximum current of 45.9 A. Maximum torque output is 54.0 Nm. The motor has a 100-size standard length 'A' design, keyway shaft, no holding brake, and 11,200 mH winding inductivity. The output shaft incorporates a sealing ring, and the system carries an IP65 rating for ingress protection.

Frequently Asked Questions

What motion-control role does MSK100A-0300-NN-S1-AP0-NNNN serve in automated equipment?

This IndraDyn S servomotor delivers continuous 17.0 Nm at standstill and peak 54 Nm, enabling accurate axis control for indexing, feed drives and synchronized webs. Its typical deployments include industrial automation cells, printing presses and metal-forming systems.

How does the optical singleturn encoder with Hiperface improve feedback on MSK100A-0300-NN-S1-AP0-NNNN?

The optical sensing with 128 sine/cos periods yields fine interpolated position and smooth velocity control, while the Hiperface interface carries both analog sin/cos and digital parameter data. Its combination reduces noise susceptibility and simplifies commissioning with electronic typeplate data.

Why specify natural-convection cooling instead of forced-air for MSK100A-0300-NN-S1-AP0-NNNN?

The natural convection eliminates fan maintenance and ingress paths while sustaining the stated continuous current/torque ratings at thermal equilibrium. It’s advantageous in hygienic lines, compact enclosures or applications where airflow management is constrained.

What does “A-side power connector” change in cabinet and cable routing for code MSK100A-0300-NN-S1-AP0-NNNN?

The A-side orientation standardizes motor-end routing for easing strain-relief layout and parallel runs with feedback cables. Its predictable connector geometry reduces bending-radius issues in multi-axis assemblies and accelerates field replacement.

How do the torque/current limits of MSK100A-0300-NN-S1-AP0-NNNN influence servo sizing?

The 11.6 A continuous at standstill and 45.9 A maximum can match drive amplifiers and supply sizing to transient load profiles while keeping thermal headroom. Its 17.0 Nm continuous/54 Nm peak supports aggressive acceleration without saturation.
