Product Description:

The MSK076C-0300-NN-M2-UG0-RNNN is manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it drives automated axes that demand precise torque and position control. The unit is delivered in motor length C and is supplied without a holding brake, so machines relying on drive torque or external clamps can hold position during power-off states. Its operating role is focused on closed-loop motion where repeatable speed regulation and accurate positioning are required.

Thermal management is handled by natural convection, allowing the housing fins to dissipate heat without forced airflow or liquid circuits. Position data travels through the EnDat2.1 serial interface, which supports bidirectional communication for online diagnostics and parameter storage. The optical encoder generates 2048 signal periods per mechanical revolution, and internal interpolation by the drive provides fine position resolution for smooth velocity loops. Because the measuring system is multiturn absolute, the shaft angle and complete revolution count are retained after shutdown, which can eliminate homing cycles at startup. Mechanical coupling is simplified by a plain shaft, allowing the use of custom hub couplings or pulleys without a keyway. The encoder uses optical scanning technology to maintain high signal linearity, and the code disk data remains accurate after many thermal cycles.

The rotor-to-stator build follows an increased concentricity design, giving low runout for applications where radial force variation must remain within tight limits. For flexible cabinet wiring, the feedback connector is rotatable through 240°, so the cable exit can be aligned with the least obstructed path. The motor frame conforms to size 076, which fits mounting flanges in that standardized diameter class. Its electromagnetic package uses winding code 0300, which sets the voltage constant and rated torque for this motor version.
