Product Description:

The MSK076C-0450-NN-M1-UG1-NSNN is a synchronous servo motor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. It converts electrical energy into controlled torque and speed, enabling coordinated positioning and velocity control in automation cells such as material-handling gantries and high-speed packaging stations. Its size 076 frame and length C stator provide a compact footprint for moderate-power axes.

Heat generated by the windings is carried away by natural convection, removing the need for forced airflow and simplifying system layout. The integrated electrically released holding brake supplies 11 Nm of static torque to secure vertical loads when power is removed. A housing certified to IP65 keeps dust and low-pressure water jets from reaching internal components, which is useful in washdown areas. The optical feedback system produces 128 signal periods per mechanical revolution, allowing the drive to interpolate fine position data for smooth velocity loops. Reliable operation is maintained between 0–40 °C, so the motor can be installed in standard machine enclosures without dedicated cooling circuits. A standard version with explosion protection is available for hazardous zones, and the encoder connector can be rotated 240° for streamlined cable routing.

The feedback chain uses the Hiperface interface and employs optical scanning in a Multiturn Absolute format, letting the controller read absolute position across 4,096 turns without a homing cycle. The motor uses winding code 0450 and an insulation class of 155, matching compatible drive modules. A cylindrical plain shaft eliminates keyseat stress and supports backlash-free clamping couplings on precision gearboxes. Because the encoder housing can swivel and the frame follows the 076 family geometry, cable routing and mounting space remain consistent across similar machines.
