Product Description:

The MSK076C-0450-NN-S1-UG1-NNNN belongs to the MSK IndraDyn S Synchronous Motors series manufactured by Bosch Rexroth Indramat. It is an AC synchronous servomotor intended for closed-loop positioning and velocity tasks in automated assembly lines, packaging machinery, and material-handling axes. By combining a permanent-magnet rotor with high-resolution feedback, the unit allows precise torque production directly from the drive controller and supports accurate motion without requiring oversized transmission components. This operating concept is well suited to axes that need repeatable starts, stops, and speed changes during normal production cycles.

This motor relies on natural convection for heat dissipation, so the housing surface serves as the primary thermal path without auxiliary fans. The motor has a frame size of 076, which provides a mid-range stator diameter suited for moderate continuous torque demands, and the overall length code is C, which indicates an extended active lamination stack for higher power density. Winding code 0450 identifies the electrical resistance and inductance values that the matching IndraDrive inverter must accommodate. A plain shaft is provided for direct coupling to backlash-free clamping hubs or low-inertia pulleys. During power loss, an electrically released holding brake can restrain stationary loads with 11 Nm of torque.

Motion feedback is generated by a Hiperface interface that transmits absolute position data from the single-turn optical encoder. Each mechanical revolution is subdivided into 128 signal periods, allowing fine interpolation for smooth speed control and stable low-speed operation. The encoder connector uses a rotatable 240° plug, so the cable exit can be aligned to reduce bending stress in compact installations. This arrangement helps simplify cable routing where space is limited around the motor and adjacent machine structure.
