The Bosch Rexroth MPN R911373778 (MSK100B-0400-NN-S3-AP1-NNNN) is an IndraDyn S synchronous servomotor featuring natural convection cooling and a power connector on the A-side. It utilizes a singleturn capacitive Hiperface encoder with 16 signal periods. The motor is equipped with a shaft with keyway, complies with DIN 42955 flange standards, and has a motor size of 100 and length B. Operating within 0°C to 40°C, the unit has four pole pairs and supports versatile installation. The holding brake provides 32 Nm of torque, with a brake moment of inertia of 0.0012420 kg·m² and is electrically released. Electrical specifications include a winding code of 0400, continuous current at standstill (100 K) of 30.8 A, continuous torque at standstill of 33.0 Nm, maximum current of 106.7 A, maximum torque of 102.0 Nm, and a winding inductivity of 3,100 mH. The housing may be affected by aggressive substances leading to potential corrosion. Disconnection or connection of connectors under load can result in ignition sparks. The motor incorporates a single-channel temperature monitoring system and is exclusively compatible with Bosch Rexroth drive systems.

Frequently Asked Questions

What continuous current frames thermal limits on the MSK100B-0400-NN-S3-AP1-NNNN?

Operation at 30.8 A continuous maintains 33.0 Nm at standstill under 100 K constraints, allowing extended holds without exceeding insulation or bearing temperature targets.

How much peak torque is available for rapid moves on the MSK100B-0400-NN-S3-AP1-NNNN?

Short bursts reach 102.0 Nm with 106.7 A, enabling quick acceleration phases before the controller transitions to fine correction at low error bands.

Why specify a keyed shaft on the MSK100B-0400-NN-S3-AP1-NNNN?

Positive coupling transfers up to 102.0 Nm without micro-slip, preserving phasing accuracy through frequent reversals in indexing or synchronized conveyor drives.

How does winding inductivity influence servo smoothness on the MSK100B-0400-NN-S3-AP1-NNNN?

With 3,100 mH, current transitions flatten, improving torque linearity and minimizing ripple that would otherwise appear during low-speed contouring or probing cycles.

What does the rated speed code represent for the MSK100B-0400-NN-S3-AP1-NNNN?

A 0400 designation guides frequency mapping so 33.0 Nm hold and 102.0 Nm surge sit within planned thermal envelopes and expected efficiency zones.

Internal Product Review

For resilient signal quality, the MSK100B-0400-NN-S3-AP1-NNNN centers on capacitive singleturn feedback. That sensor choice favors contamination resistance and stable edge detection while retaining straightforward A-side power routing and natural-convection simplicity in standard machine frames, making it top rated.
