The Bosch Rexroth Indramat MSK101D-0200-NN-S2-AP0-RNNN from the MSK IndraDyn S Synchronous Motors series is a high-performance IndraDyn S Synchronous Servomotor designed for precision motion control. This Product Type features a compact Motor Size 101 frame and a Motor Length D housing with increased concentricity for optimal mechanical balance. It delivers up to Maximum Torque of 160.0 Nm and supports a Rated Speed Code 0200 for dynamic speed applications. Built without a holding brake, the servomotor relies on its robust shaft with keyway and natural thermal management for reliable operation.

Featuring state-of-the-art Encoder Technology Optical and a singleturn Encoder Turn Type with an Encoder Resolution of 2048 signal periods, the MSK101D ensures ultra-precise feedback via the high-speed EnDat2.1 interface. Electrical integration is simplified through the front-mounted Power Connector A-Side, while the winding's inductivity of 6000 mH provides smooth current transitions. Standstill performance is exceptional, with a continuous current at standstill (100 K) of 26.8 A delivering a holding torque of 57.0 Nm. The servomotor can handle peak demands up to Maximum Current 99.9 A without derating.

Natural convection Cooling eliminates the need for external cooling infrastructure and reduces maintenance overhead. The rugged design and concentric rotor-stator alignment minimize vibration and acoustic noise, enhancing system longevity. With a standardized mechanical footprint and industry-leading encoder interface, the MSK101D-0200-NN-S2-AP0-RNNN is ready for fast commissioning and seamless integration into advanced automation systems.

Frequently Asked Questions

With a continuous current of 26.8 A at standstill, how much thermal margin is available for short bursts?

The motor’s thermal design must absorb peak currents (up to 99.9 A) without overheating; the safe duty cycle depends on the thermal time constant and ambient cooling capability. You should ensure that repetitive torque peaks do not overheat the windings over your duty cycle.

How does EnDat 2.1 with 2048 signal periods singleturn resolution impact closed-loop performance?

It enables highly accurate absolute position feedback at fine resolution (≈0.18° per period), reducing drift and improving servo stability. The EnDat 2.1 protocol also supports integrity checks and diagnostics, which helps in predictive maintenance.

Why is “increased concentricity” in the D-length version beneficial for precision?

Better concentricity means reduced rotor–stator runout and lower vibration torque ripple, improving smooth motion and reducing bearing loads. It helps in high-precision applications like machine tools or robotics where minimal eccentric error is critical.

How does natural convection cooling limit continuous output power?

Without forced cooling, the motor dissipates by ambient air, so its thermal rating is constrained by ambient temperature and mounting orientation. In high-duty applications, you must check whether additional cooling (vent or fan) or derating is needed.

What are practical constraints when integrating the front-mounted A-side power connector?

Cable routing must allow clearance in front of the motor and avoid obstructing maintenance access. Also, the connector insertion force and sealing must be considered for vibration environments to prevent signal or power dropouts.
