Product Description:

Bosch Rexroth Indramat manufactured the MSK071D-0450-NN-M1-UG1-NNNN as part of the MSK IndraDyn S Synchronous Motors series. This IndraDyn S servo motor supplies closed-loop rotary motion for automated axes that require repeatable speed and position control during continuous operation. Its standard configuration fits mid-frame machinery, delivering a reliable interface between a Rexroth drive and mechanical load in packaging lines, gantries, indexing tables, and similar automated handling equipment.

Cooling is managed by natural convection, so heat is transferred from the housing surface without auxiliary fans. The feedback connector is rotatable 240°, allowing the cable to exit in multiple directions to match cabinet layouts and machine clearances. Position data is transmitted through the Hiperface digital interface, which also carries motor data to the drive for electronic identification. The encoder produces 128 signal periods per revolution, providing fine resolution once interpolated by the controller. A spring-applied, electrically released brake supplies 23 Nm of static holding torque, securing vertical or load-suspended axes during shutdown. Winding code 0450 sets the electrical constants for torque production, while the D length class balances power density with installation depth.

The encoder uses optical scanning, which helps maintain accuracy across temperature shifts and supports stable signal quality during continuous axis movement. It also uses multi-turn absolute feedback, so the axis reports its exact position after power cycles without requiring a homing move. Mechanical integration is simplified by the motor size 071 frame, which gives a shaft center height that aligns with common gearboxes in mid-size servo assemblies. The motor has a plain shaft that mates with clamp couplings or shrink discs without key backlash, which is useful where reversing motion and precise indexing are required.
