Product Description:

The MSK076C-0300-NN-M1-UG1-NNNN servomotor is manufactured by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. Classified as an IndraDyn S synchronous servomotor, it converts three-phase drive power into accurate rotary motion for positioning axes, conveyors, and feed drives used in automated equipment. The C-length housing provides room for the selected 0300 winding while maintaining the mechanical envelope set by the 076 frame size. Integrated feedback electronics and a rotatable 240° connector simplify installation inside compact machine frames and enable direct communication with Rexroth drive controllers.

Cooling by natural convection dissipates winding heat into the surrounding air without fans or liquid circuits, so cabinet designs only need unobstructed airflow paths around the motor. Position data travel over the Hiperface protocol, allowing simultaneous power and digital feedback through a single hybrid cable. The optical scale inside the encoder offers 128 signal periods per revolution, and its optical sensing principle provides high immunity to magnetic interference. Because the encoder stores multi-turn information, the drive receives absolute position over 4,096 revolutions; this memory is delivered by the multi-turn absolute architecture and eliminates homing routines after power cycles.

For load holding during shutdowns, an electrically released brake produces 11 Nm of static torque that locks the shaft until power is restored. The drive end uses a plain shaft, permitting direct coupling with compliant hubs or pulleys where zero-backlash clamping is preferred. Mechanical geometry corresponds to frame code 076, and electromagnetic behavior is set by winding code 0300, giving a fixed relationship between rated voltage, current, and torque. The standard design and housing allow mounting without additional cooling equipment.
