Product Description:

The MSK071D-0300-NN-S1-UG0-NPNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It is intended for precise closed-loop positioning or velocity control on packaging lines, pick-and-place axes, and other motion tasks. High-resolution feedback and compact mechanical dimensions help the motor fit machines that require accurate motion without using excessive installation space.

This motor relies on natural convection to remove heat, so no external fan or liquid circuit is required when it operates within its rated load profile. Its mechanical interface is a B5 flange assembly, allowing direct bolting to gearboxes or machine frames without additional brackets. The feedback connector is rotatable through 240°, which gives wiring flexibility in tight cabinets. Position data are transmitted over the Hiperface protocol, and the optical encoder delivers 128 signal periods per revolution. Because the encoder is single-turn and optical, it reports absolute position for one mechanical turn without gear reduction. The 0300 winding code identifies the electrical characteristics of the stator, while size 071 and length D indicate the active stack dimensions that affect continuous torque. The stator layout helps keep thermal gradients low during sustained duty.

An enclosure rating of IP65 protects internal components from dust and low-pressure water jets, supporting direct machine mounting without secondary covers. The motor can run in ambient temperatures from 0 to 40 °C without derating, provided free airflow is available around the housing. A plain shaft simplifies coupling to timing belts or zero-backlash clamping hubs, and the unit is supplied without a holding brake for applications that rely on drive torque or external locks to maintain position. Its insulation system is rated Class 155, enabling the windings to tolerate elevated temperatures over long service intervals while maintaining dielectric integrity.
