Product Description:

The MSK075C-0454-NN-S1-UG1-NNNN is a synchronous servomotor built by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This product type converts controlled current from an IndraDrive amplifier into regulated torque and speed for automated axes, supplying repeatable rotary motion in material-handling, packaging, and printing equipment. It is supplied in a standard mechanical design that fits directly into machine frames, and its feature set centers on heat removal, encoder feedback, and braking support for continuous-duty operation. The motor is intended for applications that require stable motion response, accurate positioning, and dependable behavior during repeated production cycles.

Thermal dissipation relies on natural convection, meaning heat leaves the housing through ambient airflow without auxiliary fans or liquid circuits. Feedback is exchanged through a Hiperface interface that carries power and bidirectional data, allowing automatic parameter transfer when the drive starts. The optical disk delivers position information at 128 signal periods, which supports smooth velocity regulation and consistent position tracking. The sensing element uses optical scanning, so feedback quality is not affected by winding temperature. To simplify cable routing, the encoder plug is rotatable through 240°, which allows the connector to be positioned for the available installation space while maintaining proper cable alignment.

The encoder is a single-turn variant, so it reports absolute rotor angle within one mechanical revolution. Motion is secured during power loss by an electrically released brake rated at 23 Nm, which helps hold the axis when supply power is removed. The motor belongs to size code 075, and its length classification C balances torque density with installation depth for moderate-power applications. A plain shaft without a keyway permits backlash-free coupling through clamp hubs or shrink-disc bushings, creating a smooth mechanical interface for precision assemblies. This shaft style is well suited to drive trains that rely on friction-locked connections instead of keyed torque transmission.
