The R911328221 (MSK050B-0450-NN-S1-UP0-NNNN) is a Rexroth Indramat synchronous servomotor, part of the IndraDyn S series, with motor size 050 and length B. It features a standard shaft with keyway, no holding brake, and a rotatable encoder connector (240°). The motor uses singleturn optical encoder technology (Hiperface interface, 128 signal periods). Cooling is by natural convection. Key specifications include a continuous current at standstill (100 K) of 3.2 A, continuous torque at standstill (100 K) of 3.4 Nm, maximum current of 11.2 A, maximum torque of 9.0 Nm, and winding inductivity of 33,600 mH. The unit can reach up to 6000 RPM, operates at noise levels below 75 dB, and has a thermal time constant of approximately 8 minutes. Proper grounding is required due to leakage current.

What advantage does the keyed shaft design of the MSK050B-0450-NN-S1-UP0-NNNN motor provide?

The keyed shaft of MSK050B-0450-NN-S1-UP0-NNNN motor ensures reliable torque transfer between the motor and connected load, minimizing slippage under high load conditions. This improves mechanical stability in long-duration operations.

How does the 33,600 mH winding inductivity benefit motor operation?

The high winding inductivity ensures smoother current flow during acceleration and deceleration phases. This minimizes torque ripple and improves overall performance in dynamic motion profiles.

In which industries is the MSK050B-0450-NN-S1-UP0-NNNN motor commonly used?

The MSK050B-0450-NN-S1-UP0-NNNN motor is widely applied in packaging, robotics, and electronic assembly industries. Its precise feedback and smooth performance support high-speed, high-accuracy automation requirements.

How does the continuous current at standstill support system stability?

The 3.2 A standstill current enables the motor to maintain stable torque without overheating. This helps in load retention during pauses in automated cycles.

Why is the singleturn encoder significant in the MSK050B-0450-NN-S1-UP0-NNNN motor?

The singleturn encoder of MSK050B-0450-NN-S1-UP0-NNNN motor provides precise feedback within one revolution, ideal for short-stroke applications. This increases positioning accuracy without requiring multiturn tracking.
