Product Description:

Bosch Rexroth Indramat’s MSK075C-0450-NN-S1-UG0-NNNN belongs to the MSK IndraDyn S Synchronous Motors series and functions as an AC servomotor for closed-loop motion axes in industrial automation. The unit is intended to deliver precise torque control and reliable position feedback for packaging machinery, pick-and-place gantries, and other multi-axis systems that depend on accurate motion coordination. Its synchronous motor design supports stable rotary output when the drive regulates speed and position under changing load conditions. This makes the motor suitable for applications where repeatable movement and consistent axis response are important during continuous production.

The motor uses natural convection for heat dissipation, so surrounding enclosure airflow is sufficient without auxiliary fans. Signal feedback is carried through a Hiperface interface, enabling bidirectional data exchange between the encoder and the drive. The feedback connector is rotatable through 240°, which helps simplify cable routing in tight cabinets and confined machine layouts. Position measurement uses 128 signal periods, giving fine angular resolution when the drive interpolates the incremental tracks. The encoder uses optical scanning technology, so signal generation is contact-free and avoids the wear associated with mechanical sensing elements. This feedback arrangement supports accurate motor control while keeping the connection layout flexible.

The motor is supplied without a holding brake, so static load retention must be provided by the drive or an external locking device when power is removed. Housing length code C and frame size 075 establish the motor’s overall dimensions and mounting interface. The stator uses winding code 0450, which corresponds to the electrical characteristics expected by a compatible inverter. A plain shaft transmits torque to couplings or gearheads, and the single-turn optical encoder returns absolute position within one revolution for startup without a homing cycle. The plain shaft arrangement also suits direct-coupling installations where added shaft hardware is not required.
