Product Description:

The MSK075C-0450-NN-S1-UG1-NNNN is manufactured by Bosch Rexroth Indramat and belongs to the MSK IndraDyn S Synchronous Motors series. It is an IndraDyn S synchronous servomotor intended for closed-loop positioning and velocity control on automated production lines, packaging stations, and material-handling axes. When paired with a compatible drive, it converts electrical command values into controlled rotary motion for synchronized machine axes. Integrated motor feedback allows the control loop to correct speed and position deviations during changing loads. Typical uses include packaging equipment, transfer units, and positioning assemblies that need repeatable servo response. The C-length housing provides more active material than shorter versions in the same frame, which helps raise continuous torque for demanding motion tasks.

The motor relies on natural convection for heat dissipation, so airflow around the housing must remain unobstructed during operation. Its rotatable 240° encoder connector simplifies cable routing while preserving seal integrity, and it helps when cable exits must be redirected in tight machine spaces. Feedback is transferred over the Hiperface protocol, and the optical sensor delivers 128 signal periods per mechanical revolution for precise incremental motion. Motor category code 075 identifies the frame size and indicates the shaft height and flange pattern used with compatible drive packages. Winding code 0450 identifies the electrical resistance and inductance values expected by the drive controller, which influence acceleration capability and continuous current demand. The standard housing design avoids liquid-cooling or forced-air accessories.

An electrically released holding brake is integrated, delivering a static torque of 23 Nm so vertical axes remain secure during power loss. Output is transferred through a plain shaft, which supports backlash-free coupling with clamped hubs or shrink discs. Position data are captured by an optical scanning method. The absolute track uses a single-turn layout, so the motor reports a unique position within each 360° rotation without referencing. This arrangement does not include multi-turn memory hardware and suits axes that only need absolute position within one revolution.
