Product Description:

The MSK071E-0450-FN-S1-UP0-NNNN is an IndraDyn S synchronous servo motor produced by Bosch Rexroth Indramat and part of the MSK IndraDyn S Synchronous Motors series. As a compact torque source, it is installed in automated machinery to translate electrical drive commands into precise rotary motion for positioning, feed, or spindle functions. The encoder connector can be rotated through 240° to align the cable exit with machine wiring ducts.

This unit is built on motor size 071 with the elongated housing length code E, a combination that increases active stack height for higher continuous torque while keeping the mounting footprint narrow. The motor has an IP65 protection rating, so dust ingress is prevented and low-pressure water jets can be tolerated during washdown. Thermal energy from the stator windings is carried away by liquid cooling, allowing the motor to sustain output without relying on airflow inside crowded cabinets. Winding code 0450 identifies the resistance and inductance values expected by the drive controller for correct current regulation. A standard mechanical design is used, and the keyed shaft provides positive torque transfer to couplings or pulleys without relying on friction alone.

The permitted ambient temperature range is 0–40 °C, which matches typical shop-floor conditions without requiring derating under normal HVAC operation. Position feedback is delivered through a Hiperface interface, and the optical sensor generates 128 signal periods per revolution in single-turn format so the controller can determine absolute position within one turn. Insulation class 155 allows the windings to endure elevated operating temperatures without electrical breakdown. The motor is supplied without a holding brake, so any static load must be secured by external clamping or maintained drive torque.
