Product Description:

The MSK100A-0300-NN-S1-BP0-NNNN is a synchronous servomotor produced by Bosch Rexroth Indramat and included in the MSK IndraDyn S Synchronous Motors series. It is intended for position-controlled axes in assembly machines, packaging lines, and other automation cells that require precise torque and speed regulation. As an IndraDyn S class device, it combines permanent-magnet excitation with electronic commutation to deliver repeatable motion profiles in servo loops. This operating principle supports smooth acceleration and stable low-speed control during indexing, feeding, and synchronized transfer tasks. Integration with IndraDrive controllers allows parameter storage inside the encoder memory.

Heat is removed purely by natural convection, so the machine frame must allow unobstructed airflow around the stator housing. Position feedback is delivered through a Hiperface interface that carries both commutation and absolute angle information. The built-in optical scanner resolves the code disc into 128 signal periods, producing fine angular resolution suitable for high-bandwidth velocity loops. Because the sensing principle is optical, it avoids the signal variation associated with magnetic tracks. The encoder is of the single-turn type, supplying exact rotor position within one revolution without the extra complexity of multi-turn counting.

The mechanical format follows length A in motor size 100, providing a compact envelope while still accepting the 0300 winding for moderate continuous current demands. Output torque is coupled through a shaft with keyway, which allows common keyed hubs and couplings to transmit drive force without special machining. Power is cabled on the B-side, helping keep the motor power connection oriented consistently in compact machine layouts. The winding code 0300 balances speed and torque for general-purpose motion. The unit is delivered without a holding brake, so static load retention must be handled by the drive or by external mechanical means when the axis is stopped.
