Product Description:
The MSK076C-0450-NN-M3-UP1-NNNN is a servo motor manufactured by Bosch Rexroth Indramat and assigned to the MSK IndraDyn S Synchronous Motors series. As an IndraDyn S synchronous servomotor, it converts controlled electrical energy into precise rotary motion for positioning, feed, or spindle axes in automated machinery. It is suited for medium-frame packaging machines, handling modules, and assembly robots.
Heat is removed solely through natural convection, so no forced-air or liquid-cooling hardware is necessary and cabinet airflow must accommodate the motor’s radiant losses. The encoder connector is rotatable through 240°, which simplifies cable routing in cramped assemblies. Feedback is exchanged over the Hiperface digital protocol, which carries position and parameter data on a shared pair of conductors. Internal sensing uses a capacitive track that delivers 16 signal periods per mechanical revolution, allowing fine interpolation inside the drive. Because the measuring principle is capacitive, the signal resists magnetic stray fields and maintains accuracy even when ferrous components are nearby. A standard mechanical design and winding code 0450 match the motor with drives that supply the correct voltage-frequency profile for its electromagnetic circuit.
Position memory across power cycles is handled by a multi-turn absolute encoder, which eliminates homing routines after shutdowns. The electrically released brake supplies 11 Nm of static torque for secure holding on vertical axes, and it engages automatically when control power is removed. An enclosure rating of IP65 seals the stator against dust and water jets, while the output is a shaft with a keyway for positive torque transmission to couplings or gearboxes. Thermal class 155 insulation supports continuous winding temperatures that align with the 0 to 40 °C ambient range. The size 076 motor has a C-length housing that balances torque density with installation space.
