Product Description:

The MSK071E-0302-NN-S1-UG0-NNNN is an AC servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts drive current into precisely controlled torque and speed for positioning axes in automated assembly lines, packaging cells, and similar motion tasks. The manufacturer supplies this model as a standard design unit intended for integration with Rexroth IndraDrive controllers and other compatible drive platforms used in industrial automation.

Thermal management relies on natural convection, so heat leaves the housing without fans or coolant circuits and the motor should be mounted where airflow is not blocked. An IP65 enclosure protects internal components against dust ingress and low-pressure water jets, allowing installation on open machine frames. Position feedback is provided through a Hiperface optical encoder that outputs 128 signal periods, supporting high-resolution speed and position loops in the drive. Because the unit is supplied without a holding brake, any static load must be secured by the drive or by external mechanics during power loss. The plain shaft couples directly to gearboxes or belt pulleys, and the 071 frame size balances torque density with a compact footprint.

The feedback connector is rotatable through 240°, so the cable exit can be aligned with cabinet routing constraints without twisting the housing. The encoder is a single-turn unit, which means it reports absolute rotor position within one revolution and is suitable for axes that home after each power cycle. Continuous operation is permitted at ambient temperatures from 0 to 40 °C, and the windings use insulation class 155 to support the motor's thermal capability. The E-length stator supports consistent torque output while keeping overall mass suitable for gantry or delta robot installations.
