Product Description:

The MSK071D-0300-NN-S2-UP0-RNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. In automated machinery, it converts commanded current from a drive controller into precise rotary motion, enabling cyclic positioning and speed regulation of axes such as feeders, gantries, and packaging spindles. Its compact frame and closed housing support installation inside mechanical modules where accurate, feedback-controlled motion is required. This operating principle suits machines that require repeatable starts, stops, and steady-speed running within a compact installation space.

It relies on natural convection for heat dissipation, so enclosure airflow must remain unobstructed to keep the stator within its allowable thermal range. The mechanical layout uses an increased concentricity design that lowers shaft runout and supports precise coupling with gearboxes. A 240° rotatable encoder connector simplifies cable routing during installation, while the digital feedback path uses the EnDat2.1 interface for bidirectional position data. Inside the encoder, a disk with 2048 signal periods supplies the controller with fine incremental tracks. The motor uses winding code 0300, frame size 071, and length class D, which correspond to its electrical behavior and housing depth.

The sensing assembly employs optical scanning to detect lines on the code disk, and its single-turn format reports the absolute shaft angle within one revolution, eliminating homing cycles after startup. Sealing meets IP65, protecting windings and bearings from dust ingress and low-pressure water jets when the gland plate is correctly installed. The drive end uses a shaft with a keyway, allowing direct torque transfer to pulleys or couplings without slip. The unit is supplied without a holding brake, so static load retention must be handled by drive torque or external clamping devices. Continuous service is permitted at ambient temperatures from 0 °C to 40 °C, and the insulation system uses Class 155 materials for sustained thermal resistance.
