Product Description:

The Bosch Rexroth Indramat MSK071D-0300-NN-M1-UG1-NSNN is a servomotor in the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts precise electrical commands from a drive into controlled mechanical rotation for positioning or speed-regulated axes in automated machines. It is suitable for packaging, printing, and general handling equipment that requires accurate closed-loop motion. The motor works within the IndraDrive architecture to support responsive speed and position control during changing load conditions.

The unit relies on natural convection cooling, so heat is carried away through its surface without forced airflow. Feedback is handled through a Hiperface digital interface, and this bidirectional channel lets the drive read encoder data and identification information over the same cable. The optical encoder delivers 128 signal periods per revolution, giving high interpolation potential for fine position control. An electrically released holding brake supplies 23 Nm of static torque, allowing the axis to remain locked when power is removed. The housing is rated to IP65, which helps protect internal parts from dust and low-pressure water jets commonly found in industrial settings.

The permitted ambient temperature range is 0 to 40 °C, allowing full-rated operation in typical factory conditions. Insulation class 155 supports sustained winding temperatures associated with demanding duty cycles. Winding code 0300 identifies the stator version used for the motor’s electrical characteristics, and size code 071 indicates the related flange pattern and rotor diameter. A rotatable 240° connector helps with cable routing, while the multi-turn absolute optical encoder tracks position beyond one revolution. The motor also uses a plain shaft for backlash-free couplings, and the D-length housing provides the required installation length for this configuration.
