Product Description:

The MSK071D-0300-NN-S1-UP1-NNNN synchronous servomotor is manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for closed-loop axis control, it supplies responsive torque and speed for automated packaging lines, material-handling gantries, and coordinated robotic joints. A standard MSK housing, an integrated optical encoder, and an electrically released holding brake let the motor maintain position accuracy while fitting directly onto IndraDrive power stages without additional adapters.

The active section follows size code 071 and length code D, establishing a compact frame that balances torque density with installation depth. A keyed mechanical interface is provided by the shaft with keyway, so transmitted torque is locked against slip in couplings and pulleys. Load retention during power-off is handled by the internal brake, which can withstand up to 23 Nm of static torque and releases automatically when the drive supplies excitation voltage. Electromagnetic performance is determined by winding code 0300; this code fixes the phase resistance and inductance values used by the matching drive controller for current regulation, thermal modeling, and overload supervision.

Thermal management relies on passive natural convection, allowing the motor to dissipate heat without external air movers in clean cabinet installations. Motion feedback is produced by an optical encoder that communicates through the Hiperface serial interface. The sensor delivers absolute position data over 128 signal periods per mechanical revolution and supports single-cycle homing because it is a single-turn device. A rotatable 240° connector permits the feedback plug to be oriented toward the cable track, easing routing in tight enclosures while keeping strain relief within specification.
