The R911381291 (MSK050B-0300-NN-S2-UG0-RSNN) is a synchronous servomotor engineered for environments requiring explosion protection. It utilizes natural convection for cooling and features a plain shaft and a 050 motor size and B length. The stator incorporates a KTY84 temperature sensor to monitor housing temperature, issuing warnings if it exceeds 140°C. Motor parameters include a 0300 winding code, 2.0 A continuous current at standstill (100 K), 3.4 Nm continuous torque at standstill (100 K), 7.2 A maximum current, and 9.0 Nm maximum torque, with a winding inductivity of 76,400 mH. The integrated optical encoder uses EnDat2.1 interface with 2048 signal periods resolution, is single-turn, and has a rotatable connector (240°). The motor does not include a holding brake and should be installed, maintained, and repaired only by qualified personnel using suitable protective equipment. Housing cleanliness and correct storage practices are essential for performance and longevity.

Frequently Asked Questions

Why is natural convection cooling suitable for this servomotor?

The cooling method eliminates the need for auxiliary fans, reducing system complexity. This improves reliability in compact machine designs with limited airflow.

How does the rated speed code 0300 affect motor performance?

The 0300 speed code defines the motor’s nominal operating speed class. It balances torque output and thermal performance in demanding automation tasks.

How does explosion protection enhance the MSK050B-0300-NN-S2-UG0-RSNN motor?

The explosion protection of MSK050B-0300-NN-S2-UG0-RSNN motor safeguards operation in hazardous environments. This feature extends the motor’s reliability in chemical or dust-prone industrial settings.

Why is the optical singleturn encoder with 2048 periods important in this model?

The encoder provides fine angular resolution for precise positioning. This helps minimize alignment errors in applications requiring high repeatability.

How does the EnDat2.1 interface benefit the MSK050B-0300-NN-S2-UG0-RSNN motor?

The EnDat2.1 interface of MSK050B-0300-NN-S2-UG0-RSNN motor ensures fast, interference-free data transmission between the encoder and controller. This improves synchronization accuracy, particularly in robotics and semiconductor automation.
