The R911372257 (MSK100A-0200-NN-M2-BG1-RNNN) is an IndraDyn S synchronous servomotor from Bosch Rexroth's MSK series, engineered for applications requiring increased concentricity in accordance with DIN 42955. This model features a size 100 plain shaft, multiturn absolute optical encoder (EnDat2.1) with 2048 signal periods, and natural convection cooling. It operates efficiently at ambient temperatures up to +40°C and 90% humidity, with IP65 protection. The motor delivers a maximum torque of 54 Nm and maximum current of 41.4 A; continuous torque and current at standstill (100 K) are 17.0 Nm and 10.4 A, respectively. The unit includes a 32 Nm electrically-released holding brake, B-side power connector, winding code 0200, a winding inductivity of 13,900 mH, and insulation per thermal class 155. The bearing is lifetime lubricated and the output shaft seal minimizes oil leakage. The external finish is a black prime coat for enhanced durability.

Frequently Asked Questions

How does the RNNN “increased concentricity” design of MSK100A-0200-NN-M2-BG1-RNNN impact mechanics?

Its runout and alignment tolerances reduce eccentric loading on couplings and bearings for improving repeatability. It minimizes vibration-induced error and helps preserve encoder accuracy in precision axes.

What does the M2 optical multiturn encoder on MSK100A-0200-NN-M2-BG1-RNNN provide versus single-turn options?

It delivers absolute position over multiple revolutions and communicates via EnDat 2.1 for easing homing and power-loss recovery. Its resolution is specified at 2,048 signal periods per revolution for enabling fine interpolation in IndraDrive loops.

What are the cooling and duty-cycle implications of “NN” natural convection on this MSK100A variant?

The natural convection simplifies maintenance and reduces parts count, while output is limited by ambient and mounting. It supports add-on blower kits or liquid jackets on larger frames for higher continuous thermal load.

Why specify the BG1 B-side power connector orientation on MSK100A-0200-NN-M2-BG1-RNNN?

The B-side routing can shorten cable runs to overhead trays and segregate power/feedback paths to mitigate EMI. The Rexroth defines A/B/Left/Right orientations and rotatable options across the MSK family for cabinet-friendly layouts.

Is the electrically-released holding brake on MSK100A-0200-NN-M2-BG1-RNNN appropriate for vertical axes, and what torque should I expect?

Yes, energized-to-release brakes secure Z-axes at standstill or fault. Its size-100 configurations commonly offer ~32 Nm brake options in comparable MSK builds.
