The R911319974 (MSK100B-0200-NN-M2-BG0-RNNN) is an IndraDyn S Synchronous Servomotor engineered by Bosch Rexroth. It features natural convection cooling, a shaft type configured as plain shaft, and a B-side power connector. The encoder uses EnDat2.1 optical technology, providing multiturn absolute feedback with 2048 signal periods of resolution. The motor length is designated as B with a size of 100, and incorporates increased concentricity in its design. Electrical specifications include a continuous current at standstill (100 K) of 17.3 A, continuous torque at standstill (100 K) of 33.0 Nm, maximum current of 66.2 A, maximum torque of 102.0 Nm, and a winding inductivity of 7,600 mH. The winding code is 0200. It has four pole pairs and class 155 insulation, intended for use within 0 to 40°C ambient temperature. This model is supplied without a holding brake and is built to deliver precise speed and torque control for various industrial automation applications.

Frequently Asked Questions

What practical advantages does the BG0 B-side power connector give MSK100B-0200-NN-M2-BG0-RNNN in tight machine frames?

The B-side orientation simplifies cable routing away from guarding and reduces bend-radius conflicts on gantries or vertical axes. It defines “B” as the power connector on side B for consistent panelization.

What does the “increased concentricity” design mean for the plain-shaft MSK100B-0200-NN-M2-BG0-RNNN?

The tighter rotor and shaft run-out tolerances reduce radial displacement at the coupling for improving balance and minimizing torsional ripple. Its result is smoother low-speed contouring and lower vibration transmission into precision gearboxes or belt stages.

How does the specified 7,600 mH winding inductivity affect current-loop design on MSK100B-0200-NN-M2-BG0-RNNN?

Its inductance filters PWM ripple and eases EMC but constrains current-loop bandwidth. Its IndraDrive tuning typically uses lower proportional gains and appropriate current controller sampling to maintain phase margin under fast trajectories.

Can MSK100B-0200-NN-M2-BG0-RNNN participate in functional-safety schemes (e.g., STO) when paired with IndraDrive?

Yes, safety is implemented in the drive. IndraDrive options such as L3/L4 provide Safe Torque Off and related functions per Rexroth documentation. It couples mechanically while the drive enforces torque-free states.

What bearing and shaft-load guidance applies to the MSK100 size when selecting couplings or belt tensions?

It is recommended to use Rexroth’s shaft-load charts for permissible radial and axial forces, then back-calculate belt preloads and overhung loads. Its axial limits and align couplings are important to keep combined forces within diagrams across the speed range.
