Product Description:
The MSK076C-0300-NN-S2-UP1-RNNN is an IndraDyn S synchronous servomotor produced by Bosch Rexroth Indramat within the MSK IndraDyn S Synchronous Motors series. It supplies precise rotary motion and position feedback for industrial automation axes such as packaging sealers, pick-and-place heads, or gantry stages. Factory integration is simplified because the motor includes an electrically released holding brake that secures the load when power is removed.
Cooling for the unit relies on natural convection, so heat is dissipated through the housing without external fans, a factor that affects cabinet airflow planning. Position data travels through the EnDat2.1 serial interface, enabling absolute position reporting and electronic nameplate exchange with the drive controller. The integrated optical encoder provides 2048 signal periods, giving fine subdivision of each mechanical revolution for high-resolution velocity loops. Cabling is simplified because the feedback plug is rotatable through 240°, allowing the cable to exit in several directions to match the machine layout. The electrically released brake supplies 11 Nm of static holding torque, permitting vertical axis retention without external clamping. A machined rotor and stator geometry with increased concentricity further reduces radial runout during high-speed operation.
The encoder’s optical sensing principle delivers low-jitter signals, and its single-turn configuration stores the absolute angle within one revolution, which is sufficient for many indexing tasks that re-home at startup. Mechanical coupling is handled by a shaft with a keyway, providing positive torque transmission to pulleys or gear sets. Winding code 0300 indicates the coil impedance and current rating expected by MSK drives, while motor length C and size 076 set the stack height and flange footprint for the housing.
