Product Description:

The MSK071D-0450-FN-M1-UG2-NNNN is a synchronous servomotor manufactured by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. As a closed-loop drive element, it converts inverter output into precise mechanical motion for axes that require accurate speed, torque, and position regulation in packaging, printing, and general assembly equipment. The D length, 071 frame, and plain shaft geometry allow direct coupling to gearboxes or load spindles, while the standard mechanical design supports straightforward integration into cabinet-cooled or stand-alone machines.

For thermal management, the motor uses the FN cooling type and employs liquid cooling, permitting higher continuous current without external airflow. The winding code 0450 identifies the copper fill and resistance profile used with compatible IndraDrive power modules. Feedback is supplied through an optical encoder whose connector is rotatable 240°, aiding cable routing in tight panels. Position data are transmitted over the Hiperface protocol, and the sensor delivers 128 signal periods per electrical revolution. The feedback device is multiturn absolute, so the drive retains axis position through power cycles without requiring a homing move. Standard construction and housing sealing help isolate the stator from dust and cutting fluids, while the plain shaft simplifies installation when no key is required.

Mechanical holding is provided by an electrically released brake that produces 30 Nm of torque, securing vertical loads during shutdown. The enclosure meets IP65, so only shaft-end seals need additional guarding against high-pressure washdown. Continuous service is permitted between 0–40 °C, and the winding insulation system is rated for 155 °C thermal endurance. Operation outside this ambient range or with insufficient coolant will reduce service life.
