The R911321457 (MSK101C-0300-NN-M2-BG2-RNNN) is an IndraDyn S synchronous servomotor designed for integration with Bosch Rexroth drive controllers. It features a size 101, length C motor with a plain shaft and employs natural convection cooling with a cooling requirement of FN. The motor includes a B-side power connector and is equipped with an EnDat2.1 multiturn absolute optical encoder with a resolution of 2048 signal periods. Continuous current at standstill (100 K) is rated at 21.3 A, delivering a continuous torque of 36.5 Nm, with peak values of 84.2 A and 110.0 Nm, respectively. The winding inductivity is specified at 6,000 mH. It incorporates an electrically-released holding brake with a torque of 70 Nm and features increased concentricity. Bearings are designed for a service life of 30,000 operating hours. Regular routine checks of the motor housing, protective conductor connections, and connection cables are required. The motor should only be installed, operated, and maintained by qualified personnel and must be disconnected and fully de-energized prior to maintenance.

Frequently Asked Questions

How does the EnDat 2.1 multiturn absolute encoder on MSK101C-0300-NN-M2-BG2-RNNN improve commissioning and control-loop stability?

It delivers absolute position over multiple turns with bidirectional diagnostics for minimizing homing cycles and start-up overhead. Its deterministic digital interface reduces interpolation error and enhances low-speed smoothness for tight velocity and position loops.

Why specify a plain shaft on MSK101C-0300-NN-M2-BG2-RNNN instead of a keyed or serrated variant?

The plain (cylindrical) shaft allows precision friction-fit or shrink-fit couplings that minimize backlash and runout to match the motor’s increased concentricity design. It eases alignment in high-accuracy machine axes and gearhead integrations.

How does the electrically-released holding brake (70 Nm) interact with safety and power-loss events on MSK101C-0300-NN-M2-BG2-RNNN?

The spring-applied, power-to-release brake clamps on power loss for holding vertical loads or tooling at rest. It disengages cleanly when energized for motion to support safe stops in packaging, handling and press feeders.

How does 6,000 mH phase inductivity influence inverter selection and current ripple on MSK101C-0300-NN-M2-BG2-RNNN?

Its higher inductivity attenuates current ripple and improves current-loop stability for easing EMI filtering. It is important to choose IndraDrive-class inverters with suitable DC-link voltage and switching frequency to maintain dynamic response without exceeding voltage limits.

How does “increased concentricity” in this IndraDyn S design affect application accuracy for MSK101C-0300-NN-M2-BG2-RNNN?

Its enhanced rotor/shaft concentricity reduces mechanical runout for lowering cogging-related torque ripple and improving interpolation quality. Its result is smoother surface finish in milling and steadier registration in web handling.

Internal Product Review

The Rexroth Indramat’s MSK101C-0300-NN-M2-BG2-RNNN servomotor pairs a plain shaft with an electrically-released 70 Nm brake for easy integration and safe operations. It uses an optical EnDat 2.1 multiturn feedback system and gets cool through natural-convection process. This motor comes with a B-side power point for simplifying layouts. It offers 36.5 Nm of continuous and 110 Nm peak torque to suit installation with packaging, printing, robotics and metal-forming drives.
