Product Description:

The MSK071D-0200-NN-M2-UG0-RNNN is an IndraDyn S synchronous servomotor from Bosch Rexroth Indramat in the MSK IndraDyn S Synchronous Motors series. As a servomotor, it converts drive current into precise rotary motion for positioning and velocity control on automated machinery and handling axes. The model designation links motor size 071 and length D to a mechanical envelope that fits compact servo axes, and the product type confirms its role in closed-loop industrial drive systems.

Thermal management relies on natural convection, meaning heat leaves the housing without forced airflow, so the installation must allow free surrounding air. The stator uses winding code 0200, which identifies the electrical design used with compatible drive controllers. Rotor position is reported through an optical encoder that uses the EnDat2.1 serial interface with 2048 signal periods of resolution, supporting tight control loops at the drive. The encoder provides multiturn absolute feedback, preserving position across power cycles and eliminating the need for homing. Mechanical output is provided through a plain shaft, so torque transmission depends on friction or external couplings, and the internal build uses increased concentricity to keep radial runout low. The motor is supplied without a holding brake, so static load retention must be provided by external devices or drive torque.

The housing carries an IP65 rating, protecting the motor against dust intrusion and low-pressure water jets during washdown operations. Reliable operation is permitted in ambient conditions from 0 to 40 °C, so additional cooling or derating is required outside that range. The windings use insulation class 155, which supports elevated internal temperatures before insulation aging accelerates. Installation flexibility is improved by a rotatable 240° encoder connector, and the combination of size 071 with motor length D helps the unit fit into tight multi-axis assemblies without changes to standard machine frames.
