Product Description:

The MSK071D-0450-NN-M1-UP1-NNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. In industrial automation, this motor supplies accurately regulated torque and speed so that gantries, packaging stations, or machining axes can follow programmed motion profiles with precise control. The D-length mechanical frame provides additional stack height for higher continuous torque while maintaining the 071 stator diameter.

The unit is cooled by natural convection, meaning heat is removed through the housing surface without auxiliary fans, which is useful where cabinet airflow is limited. Feedback is supplied through a rotatable 240° connector that uses the Hiperface serial interface, and this single-cable protocol carries position data and power for the encoder to simplify routing. Inside the encoder, position is resolved into 128 signal periods, and each period is further interpolated by the drive to achieve high positional granularity during closed-loop control. An optical scanning method is used, providing low drift and resistance to electromagnetic noise compared with magnetic sensors. Because the sensing system is multi-turn absolute, it retains shaft position over multiple revolutions even after power loss, eliminating the need for homing on startup.

The electrically released holding brake produces 23 Nm of static torque, so vertical loads can remain stationary when the drive is disabled. Power is transmitted through a shaft with keyway, allowing direct coupling to pulleys or gearsets without relying only on friction fit. Winding identification code 0450 indicates the copper fill and electrical constants expected by a compatible IndraDrive amplifier. Motor size 071 corresponds to an 82 mm centering diameter and a consistent mounting interface used within the series.
