Product Description:

The MSK071E-0300-NN-M1-UG0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. The unit converts drive inverter commands into controlled torque and speed for positioning axes on assembly stations, pick-and-place gantries, and packaging lines. By combining a compact 071 frame with an E-length stator, the motor offers a balance between continuous power density and installation depth for machines that require rotary motion in confined spaces. This arrangement supports repeatable motion on axes that cycle rapidly between acceleration, dwell, and deceleration. Its mechanical interface follows the standard flange dimensions used throughout the series, which supports straightforward integration into compatible machine designs.

The stator windings release heat through natural convection, so the motor can be mounted close to other components without dedicated airflow hardware. For simplified cabling, the feedback plug is rotatable through 240°, which allows flexible connector positioning around the housing. Position data and electronic nameplate information are transmitted via the Hiperface interface, giving the drive immediate access to calibration values. Inside the feedback assembly, the code disk delivers 128 signal periods per mechanical turn, which the controller interpolates for high-resolution velocity loops. The motor is supplied without a holding brake, so external holding force is required when the axis must remain fixed at rest. The connector range also helps route feedback wiring in crowded machine layouts.

The sensor uses an optical pickup, which avoids magnetic drift and supports stable accuracy over the service life. Its multi-turn absolute design stores the number of revolutions mechanically, allowing the controller to recover exact position after power loss and resume closed-loop operation immediately. Drive torque is transferred through a plain shaft, which mates directly with zero-backlash couplings or gear inputs to preserve encoder fidelity. Winding code 0300 matches the motor to compatible drive outputs sized for mid-range current, so demanding acceleration profiles can be supported without exceeding thermal limits.
