Product Description:

The MSK076C-0300-NN-S3-UP0-NNNN synchronous servo motor is produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. Intended for closed-loop positioning and speed control, it converts electrical power into precise rotary motion for conveyors, gantries, and CNC tooling stations on automated production lines. The motor mates with Rexroth drive controllers through a single hybrid cable, which reduces cable routing complexity between the cabinet and the axis. Its compact housing also supports direct mounting near the work axis, helping reduce mechanical compliance and maintain responsive motion.

This model dissipates heat by natural convection, so the aluminum housing sheds warmth without fans or liquid circuits. It uses frame size 076 with length C, and winding code 0300 matches the electrical characteristics expected by the paired drive. Motion feedback travels over the Hiperface interface, where the sensor divides one revolution into 16 signal periods for position tracking. A keyed shaft transfers torque to the driven mechanism. Sealing rated at IP65 blocks dust and low-pressure water jets, and continuous service is permitted from 0 °C to 40 °C. The motor has no holding brake, so static load retention must be provided externally.

Cable orientation is flexible because the encoder plug can be rotated through 240°, allowing strain-relief hardware to clear adjacent components in tight machine layouts. The sensing system uses capacitive scanning, which resists oil mist and magnetic fields commonly found on factory floors. With single-turn functionality, the encoder reports absolute position within one mechanical revolution, which suits axes that reference at startup. An insulation class of 155 supports elevated winding temperatures and intermittent overload during changing duty cycles.
