The R911319178 (MSK071C-0450-NN-M1-UG2-NNNN) is an MSK series IndraDyn S synchronous servomotor from Bosch Rexroth, integrating a plain shaft with sealing ring and a B05 flange assembly for machine mounting. This unit features natural convection cooling, a 30 Nm electrically-released holding brake (24V, 0.94A), 10.4 A continuous current at standstill (100K), maximum current of 40.1 A, and delivers 14.0 Nm continuous and 44.0 Nm maximum torque. The optical Hiperface multiturn encoder provides 128 signal periods with a rotatable connector (240°). The servomotor uses winding code 0450, inductance of 6,700 mH, has frame size 071, and motor length C.

How does the multiturn absolute Hiperface encoder on MSK071C-0450-NN-M1-UG2-NNNN aid precise multi-axis synchronization?

It reports absolute position over multiple turns with 128 signal periods for minimizing homing cycles and drift across coordinated axes. Its Hiperface’s deterministic feedback improves velocity loop stability and phase alignment in packaging and printing lines.

What operating envelope makes MSK071C-0450-NN-M1-UG2-NNNN appropriate for machine tools and metal-forming feeders?

The 14.0 Nm continuous and 44.0 Nm peak torque, plus natural-convection cooling fits mid-torque rotary drives, indexers and feeders that require repeatable torque density without auxiliary fans. Its typical applications include machine tools and metal forming equipment.

Why is the 240° rotatable encoder connector valuable during tight cabinet or gantry layouts?

The swivel connector eases cable routing to reduce bend-radius stress and helps maintain IP sealing while aligning feedback and power paths. Its flexibility simplifies service loops on moving carriages and compact end-effectors.

How does the 30 Nm electrically-released holding brake on MSK071C-0450-NN-M1-UG2-NNNN support vertical axes?

It holds the load at standstill and during E-stop without drive torque for preventing back-driving on Z-axes or unwind spindles. Its electrical release ensures predictable engagement.

How does natural-convection cooling (Cooling FN required) influence continuous torque on MSK071C-0450-NN-M1-UG2-NNNN?

The convection relies on ambient airflow and mounting for heat rejection, while continuous torque ratings assume FN boundary conditions. Its proper spacing and panel ventilation help the motor maintain 14.0 Nm at 100 K thermal rise.
