Product Description:

The MSK071D-0300-NN-S3-UG0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat for motion tasks in automated machinery. It belongs to the MSK IndraDyn S Synchronous Motors series, a family that delivers direct, feedback-driven torque for positioning axes, gantries, and packaging equipment. Within this lineup, the model integrates a rotary position encoder and a sealed housing, so it can be mounted directly on the machine frame without extra guarding. Its purpose is to convert electrical power from an IndraDrive inverter into precisely regulated rotational movement.

This unit uses natural convection to remove heat, so airflow around the stator housing must be maintained instead of relying on fans or liquid circuits. The enclosure carries an ingress rating of IP65, which means it is dust-tight and can tolerate low-pressure water jets during operation. A plain shaft transmits torque without keyways, allowing clamp couplings to center freely on the ground surface. Rotor position is reported by a capacitive sensor, and this technology resists magnetic interference while providing an incremental pattern of 16 signal periods per electrical revolution for fine servo interpolation. The encoder connector can be rotated through 240° to orient cabling in tight cabinets, and the stator uses winding code 0300 for matching drive parameters.

The motor is rated for continuous service from 0–40 °C, and internal insulation rated to class 155 helps protect the windings when surface temperatures rise during peak duty cycles. Feedback communication follows the Hiperface protocol, allowing serial encoder data to reach the drive controller from the single-turn encoder. The absence of a holding brake lowers inertia for high-speed reversals and helps keep the rotor responsive during cyclic motion. If the axis must remain fixed at standstill, holding force must be supplied by the drive or by external mechanics, while motor length D and frame size 071 keep the package compact.
