The R911326051 (MSK101C-0300-NN-M2-AG0-RNNN) is a synchronous servomotor engineered for operation in hazardous environments, with certification for use in Zone 2 and Zone 22 explosive atmospheres in accordance with ATEX 94/9/EC directives. The motor features natural convection cooling, a plain shaft, and is supplied without a holding brake. It supports an EnDat2.1 multiturn absolute optical encoder with 2048 signal periods and is designed for an A-side power connector. The unit provides a continuous current of 21.3 A and continuous torque of 36.5 Nm at standstill (100 K), with maximum ratings of 84.2 A and 110.0 Nm respectively. The winding inductivity is specified at 6,000 mH, with increased concentricity quality and a C-length 101-size frame. Specific handling and orientation requirements apply due to the potential for high surface temperatures.

Frequently Asked Questions

What distinguishes the MSK101C-0300-NN-M2-AG0-RNNN encoder system in closed-loop motion?

It uses an optical multiturn absolute encoder with EnDat 2.1 for providing digital position values with incremental tracks (2048 signal periods) for high-resolution commutation and feedback. Its hybrid digital/analog signaling of EnDat 2.1 improves noise immunity during acquisition and supports reliable position referencing at startup.

How does natural-convection cooling influence mounting of MSK101C-0300-NN-M2-AG0-RNNN?

Its design without forced air or liquid circuits uses heat dissipated through the frame, so clear airflow paths and thermally conductive mounting surfaces are beneficial. It simplifies cabling and maintenance while preserving ingress integrity in packaging, printing and machine-tool environments.

Why is “increased concentricity” valuable for this IndraDyn S motor in precision stages?

The tighter mechanical runout reduces cogging-related torque ripple coupling to the load for improving contour accuracy and surface finish. It directly enhances path fidelity and overlay alignment in CNC spindles, pick-and-place gantries and print registration axes.

How does the A-side power connector of MSK101C-0300-NN-M2-AG0-RNNN affect cabinet/loom design?

The standardized IndraDyn S power/feedback plug connectors simplify prefabricated harnesses and strain-relief routing on the motor’s A-side. It reduces installation variance and supports consistent shielding and thermal sensor integration per Rexroth connection practices.

Why is EnDat 2.1 still widely paired with IndraDrive and third-party drives?

It’s a proven bidirectional interface providing parameter readout, diagnostics and absolute position transfer at boot. Its drive support EnDat 2.1 natively for ensuring straightforward commissioning and reliable referencing across heterogeneous lines.
