Product Description:

The MSK071E-0200-NN-M1-UG1-NNNN is an IndraDyn S synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. The motor follows the standard mechanical design and is engineered for closed-loop control of rotary axes in packaging lines, machine tools, or material-handling gantries. It combines the 071 frame size with an E length stator to provide a continuous torque profile suitable for medium-inertia loads while remaining compact for cabinet or on-machine installation.

Cooling relies on passive airflow through natural convection, eliminating the need for external blowers and simplifying enclosure layouts. The motor uses winding code 0200, which sets electrical values matched to IndraDrive controllers. Position and speed feedback are transmitted over the Hiperface interface, allowing combined digital position data and analog sine-cosine tracks for fine interpolation. An optical scanning head resolves the scale into 128 signal periods, delivering high-resolution feedback that supports smooth velocity loops even at low speeds. The motor uses a plain shaft interface that facilitates direct coupling to precision gearboxes or pulleys.

For static holding and emergency stops, an electrically released spring assembly supplies 23 Nm of brake torque, and the brake engages automatically when power is removed. The encoder stores revolution counts through multi-turn absolute functionality, so the axis retains position data without a homing cycle after shutdown. Feedback wiring exits through a connector that is rotatable through 240°, which simplifies cable routing in tight spaces. The sensing hardware relies on an optical principle, providing low hysteresis and temperature-stable signal generation. The motor has motor size 071, which matches the bolt circle and pilot diameter used across the MSK series.
