Product Description:

The MSK103D-0300-NN-S1-UG0-NNNN is a synchronous servo motor manufactured by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It is intended for position and speed control tasks in industrial automation, where precise torque production is paired with high-resolution feedback in packaging systems, handling equipment, and other automated machinery. The motor uses closed-loop feedback for accurate regulation, helping the connected drive correct speed and position deviations during changing load conditions. Its mechanical output can be coupled directly to machine elements such as gear stages, pulleys, or indexing mechanisms.

Thermal management relies on natural convection, a passive cooling method that transfers heat to the surrounding air without external fans. The stator platform identified as motor size 103 provides a housing diameter that balances torque density with installation space, while motor length D adds active stack length for higher continuous power. Electrical behavior is set by winding code 0300, so the drive controller must supply the matching rated voltage and current for proper operation. Torque is transmitted through a plain shaft, allowing backlash-free clamping hubs or couplings to be mounted directly and keeping the drive train mechanically straightforward.

Position feedback is generated by a Hiperface interface, which combines digital absolute data with incremental tracks for drive alignment. The sensor head uses optical scanning to produce clean signal edges, and it delivers one revolution of absolute position through 128 signal periods in a single-turn format. Cabling is simplified by a rotatable connector that can be turned through 240°, letting the harness exit in a suitable direction inside restricted enclosures. The motor is supplied without a holding brake, so holding torque must be provided by the drive or by an external mechanical lock during power-off states.
