The R911317625 (MSK076C-0450-NN-M1-UP1-NNNN) is a synchronous servomotor from the IndraDyn S MSK series, featuring a motor size 076 and length C. It is equipped with a 0450 winding code, a standard shaft with keyway (DIN 6885-1), and a shaft-sealing ring. The motor supports natural convection cooling and incorporates a multiturn absolute optical encoder with Hiperface interface and 128 signal period resolution. The continuous torque at standstill (100 K) is rated at 13.5 Nm with a continuous current of 8.1 A, while the maximum torque reaches 43.5 Nm and the maximum current is 54.9 A. The holding brake provides 11 Nm of braking torque and is electrically released. The housing is constructed from lightweight metal alloy, and the power connection can rotate up to 240° for installation flexibility. The winding inductivity is specified at 4,700 mH.

Frequently Asked Questions

What role does natural-convection cooling play in the MSK076C-0450-NN-M1-UP1-NNNN thermal envelope and enclosure planning?

Its passive heat rejection simplifies cabinet airflow design that reduces contamination pathways and minimizes auxiliary power needs. Its thermal behavior should be modeled with mounting orientation and ambient limits to preserve torque at standstill ratings and encoder stability.

Why is the 240° rotatable power/feedback connector advantageous on this motor in dense multi-axis frames?

The swivel orientation eases cable routing, reduces bend-radius stress and improves EMI compliance by enabling cleaner segregation of power and feedback harnesses. It also expedites maintenance by allowing tool-access without disturbing adjacent axes.

How does the 4,700 mH winding inductivity influence current ripple and drive tuning on MSK076C-0450-NN-M1-UP1-NNNN?

The higher inductivity attenuates PWM ripple and smooths current loops for easing meeting velocity ripple specs. Its controller gains should consider electrical time constants to maintain bandwidth without excessive phase lag in the torque loop.

What are integration considerations for the optical encoder (128 signal periods) regarding noise immunity and cable selection?

The use of low-capacitance, shielded feedback cables with proper 360° terminations suppress common-mode noise. It is important to maintain separation from motor power leads.

For MSK076C-0450-NN-M1-UP1-NNNN, how do 13.5 Nm continuous stall and 43.5 Nm peak torque map to motion profiles?

Its continuous segment remains below thermal limits and its reserve peak torque is for brief acceleration, contouring or disturbance rejection. It is important to validate with RMS torque calculations and thermal time constant assumptions from the drive sizing tool.
