Product Description:

The MSK076C-0450-NN-M2-UG1-RNNN is a frame-076 unit in the MSK IndraDyn S Synchronous Motors series from Bosch Rexroth Indramat. This C-length servo motor is installed in automation cells to deliver precise rotary motion under closed-loop control, acting as the mechanical workhorse for coordinated axes in packaging, printing, and handling machines. By pairing its optical multi-turn encoder with compatible drive controllers, the motor feeds absolute position data back to the motion system and supports deterministic positioning without external sensors.

Heat generated in the stator is removed through natural convection, so the housing only needs free airflow and no external fan. The enclosure carries an IP65 rating, blocking dust ingress and low-pressure water jets, which permits mounting outside a cabinet. Position feedback travels over the EnDat2.1 serial interface, and this protocol allows digital parameter storage inside the encoder while simplifying wiring to Rexroth drives. The optical scanning head resolves 2048 signal periods, and after internal interpolation the controller receives high-resolution angle data. Power-off holding is supplied by an electrically released brake that can hold up to 11 Nm, maintaining axis position on vertical loads when the drive is disabled. The increased concentricity design reduces shaft runout and improves accuracy.

A rotatable, 240° connector allows the plug to be oriented without twisting leads inside cable chains. The integrated measuring system is of the multi-turn absolute type, so the motor reports its mechanical angle across multiple revolutions even after power loss. A plain shaft output simplifies coupling to gearheads or pulleys, and the thermal system uses insulation class 155, which aligns with a continuous ambient range of 0 to 40 °C. Core electrical characteristics are set by winding code 0450, and the motor's C length balances torque with overall package size for compact dynamics.
