The R911330828 (MSK101C-0300-NN-S1-BP2-NNNN) is a synchronous servomotor from the IndraDyn S series, designed for integration in industrial automation systems. It features a 101 mm motor size with a C length, winding code 0300, and a keyed steel output shaft. The unit is equipped with a single-turn optical encoder (Hiperface interface, 128 signal periods) for precise position feedback to the drive controller. The holding brake is electrically released and provides 70 Nm torque. The servomotor operates with natural convection cooling, requires Cooling FN, and the power connector is located on the B-side. Continuous current at standstill (100K) is 21.3 A with 36.5 Nm torque, while maximum values are 84.2 A and 110.0 Nm torque. Winding inductivity is specified at 6,000 mH. The motor is suitable for operation up to 1000 meters altitude, and its construction does not include asbestos, PCB, or chlorinated hydrocarbons.

How does the Hiperface singleturn encoder (128 signal periods) in MSK101C-0300-NN-S1-BP2-NNNN improve servo control?

The sin/cos Hiperface signals enable fine interpolation in the drive for yielding high effective position granularity within one revolution and smooth commutation. It reduces low-speed ripple and enhances stiffness for precise indexing and contouring on this motor.

What are the implications of natural-convection cooling and the “Requires Cooling FN” constraint?

The motor’s thermal model assumes heat dissipation through mounting surface and ambient airflow, while cabinet layouts must avoid stagnant air and insulate from external heat sources. Its limits preserves continuous torque ratings, especially near enclosure walls or elevated ambient temperatures up to specification.

Why include an electrically-released 70-Nm holding brake on MSK101C-0300-NN-S1-BP2-NNNN?

It secures vertical or load-bearing axes during emergency stops and power loss for preventing drift when torque production ceases. Its brake is not a dynamic stopping device, while it’s for static holding, sized to resist back-driving torques within safety margins.

What advantages does a keyed shaft provide compared to a plain or shrink-fit coupling?

The keyway provides positive torque transmission and mitigates slippage under high peak torque events while simplifying hub alignment.

What does a ~75 dB(A) sound pressure level indicate for MSK101C-0300-NN-S1-BP2-NNNN in production areas?

It aligns with common workplace acoustic thresholds when mounted properly and driven within nominal switching strategies. Its mechanical transmission, fanless cooling and drive PWM settings still influence perceived noise, so system-level validation remains essential.
