Product Description:

The MSK076C-0300-NN-M2-UG1-RNNK is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MSK IndraDyn S Synchronous Motors series. Designed for precision positioning and velocity regulation, the unit converts drive-controller commands into controlled mechanical motion for packaging machines, printing lines, and general factory automation equipment. Its electromechanical design combines an optical feedback system with a compact stator winding, allowing the motor to deliver repeatable torque output while fitting into machinery frames where axial space is limited and enclosure sealing is important.

Thermal management for the motor relies on natural convection, so heat is carried away through the housing without external fans or liquid circuits. The feedback cable exits through a connector that can be rotated 240°, simplifying cable routing in tight cabinets and machine frames. Position data is exchanged with the drive over the EnDat2.1 interface, and the optical encoder disc provides 2048 signal periods per revolution for fine incremental interpolation. An electrically released holding brake supplies 11 Nm of static torque to secure vertical axes during power loss. The motor uses size 076 and length code C, while winding code 0300 matches standard MSK drive currents. For enclosure integrity, the stator body and connector assembly achieve a protection rating of IP65 against dust ingress and water jets.

The encoder stores absolute position across multiple turns through its multi-turn absolute capability, which eliminates the need for homing after shutdown. Torque is transmitted through a balanced plain shaft, which simplifies coupling to gearboxes or direct-drive loads. Continuous operation is allowed within an ambient range of 0 to 40 °C. The stator insulation system is rated class 155 to tolerate winding temperatures typically associated with modern servo cycles.
