Product Description:

The MSK071E-0300-NN-S1-UG0-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As a compact rotary actuator, it supplies controlled torque and speed to positioning tables, pick-and-place units, and other closed-loop automation axes where dynamic response and feedback accuracy are mandatory. When paired with a compatible servo drive, the motor supports precise acceleration, repeatable positioning, and stable speed control during rapid load changes. This type of motor is commonly used where short cycle times and accurate response to command changes are needed, such as indexing stations, handling modules, and compact transfer systems.

This motor relies on natural convection for heat dissipation, so surrounding airflow must be adequate to carry heat away from the housing during continuous operation. Its frame size is 071, which corresponds to the flange pattern, shaft height, and gearbox compatibility used in this motor platform. The rotor uses a plain shaft, allowing direct coupling through compression hubs or keyless clamping elements that help reduce backlash in the drive train. The motor is supplied without a holding brake, so any static load retention must be provided by external mechanical locking devices or controlled drive torque. Because cooling is passive, the installation does not require a separate fan assembly on the motor body, which helps preserve a compact outer shape and reduces moving wear components.

Feedback connectivity is simplified by a rotatable 240° hybrid connector that lets the cable exit be oriented after installation to suit limited machine space and cleaner cable routing. Signal transmission uses the Hiperface protocol, permitting high-resolution position data and electronic nameplate exchange with compatible Rexroth drives. Inside the encoder, an optical scanning system produces incremental and absolute tracks at 128 signal periods per revolution, providing finely interpolated feedback once processed by the controller and supporting accurate commutation during motion. The adjustable connector position can also help reduce cable bend stress near the motor housing when routing is restricted by nearby guards or machine frames. The feedback system is single-turn, so revolution counting beyond one turn must be handled by the control system if an application requires absolute position tracking over multiple turns. Winding code 0300 indicates the motor’s voltage constant and current range, allowing the matched drive to deliver torque within the motor’s thermal limits.
