Product Description:

The MSK071E-0200-NN-S1-UG1-NNNN is an IndraDyn S synchronous servo motor built by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a compact drive element, it delivers closed-loop speed and position control for automated handling, packaging, and machining axes that require high accuracy. The motor is intended for applications where fast response and repeatable positioning are needed without using a large frame. Its synchronous design supports stable torque production across changing load conditions during normal machine cycles.

This motor uses natural convection to remove heat from the housing, so no auxiliary fan or liquid circuit is required. Because cooling is passive, surrounding airflow can remain uncomplicated and there is no separate fan assembly to maintain. A protection rating of IP65 shields the internals from dust and low-pressure water jets, allowing cabinet-free mounting in areas with ambient temperatures from 0–40 °C. An electrically released holding brake provides 23 Nm of static torque to keep vertical or suspended loads in place when power is removed. An optical single-turn encoder supplies sinusoidal feedback with 128 signal periods for accurate commutation and position control.

The feedback package communicates through Hiperface, and the service connector is rotatable through 240° to support flexible cable routing in different machine layouts. The rotatable connector helps when the motor must be installed in tight spaces or with different cable exit directions. A plain shaft allows direct coupling to zero-backlash clamping hubs or belt pulleys, which helps keep the mechanical interface simple. The motor uses insulation class 155 and standard construction for typical industrial duty. Optical scanning technology reduces interpolation error, and the encoder supports stable feedback during repeated positioning cycles.
