Product Description:

The MSK076C-0300-NN-M1-UP0-NNNN-SA001 is a synchronous servomotor produced by Bosch Rexroth Indramat for the MSK IndraDyn S Synchronous Motors series. This motor belongs to the IndraDyn S synchronous servomotor product type and is intended for precise position and speed control in industrial automation systems where rapid response and high accuracy are required.

The unit relies on natural convection for cooling, so cabinet airflow must allow unobstructed heat dissipation without forced fans. Its encoder connector can be positioned through a rotatable, 240° range, simplifying cable routing in tight machine layouts. Position feedback is exchanged via the Hiperface interface, which carries both absolute position data and parameter storage on a single hybrid channel. The optical scanning head tracks 128 signal periods per mechanical revolution, giving fine angular resolution for smooth servo loops. Underlying this performance is an optical measurement principle, which minimizes drift and delivers stable accuracy over the motor’s service life.

The feedback system provides a multiturn absolute position reference, allowing the controller to read the rotor angle and the number of complete revolutions after power-up without homing. Mechanical coupling is handled by a shaft with keyway, ensuring positive torque transfer to pulleys or couplings. The electromagnetic package follows winding code 0300, establishing the current, voltage, and torque constants that must match the drive. Compact mechanical dimensions stem from motor size 076 and length class C, while the standard design housing is sealed against dust ingress yet omits an internal brake; the motor is supplied without a holding brake, so external means must secure loads when power is removed.
