Product Description:

The MSK071E-0300-NN-S2-UG1-RNNN is an IndraDyn S synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It provides closed-loop rotary motion by converting controlled electrical input from a compatible inverter into shaft torque at the machine axis. Because the motor is intended for servo operation, the drive can regulate speed, position, and torque in response to changing load conditions. Its synchronous design supports precise electronic commutation when paired with the appropriate servo controller. This role suits automated cells, gantry systems, and material-handling stations where repeatable acceleration, deceleration, and positioning are required throughout continuous machine cycles.

Thermal management relies on natural convection, so heat leaves the housing through surface radiation and ambient airflow without active fans or external blowers. An electrically released holding brake rated at 23 Nm holds the shaft when power is removed, which is useful on vertical axes and suspended loads. Feedback travels through the EnDat2.1 interface, and the encoder disk provides 2048 signal periods per revolution so the drive can resolve fine incremental movement. The encoder uses an optical sensing principle, supporting high resolution and stable signal quality in closed-loop servo operation. This combination of brake and feedback functions allows the axis to stop securely and restart with an accurate position reference.

The motor uses frame size 071 with winding code 0300, matching the electrical characteristics commonly used with standard IndraDrive power stages. Torque is transmitted through a plain shaft, and the signal connector can be rotated through 240° to simplify cable routing when surrounding equipment limits entry angles. A single-turn encoder layout avoids multi-turn gearing at the feedback head, which helps keep rotating inertia low. The E-length housing provides additional active material for continuous torque, while the increased concentricity build helps keep rotor runout low during rapid forward-and-reverse motion. The shaft arrangement suits direct coupling to gearboxes or belt drives, and low runout helps maintain stable motion on reversing axes.
