The R911321260 (MSK101D-0300-NN-S2-BG2-RNNN) is a synchronous servomotor from the MSK series with self-cooling via natural convection. It features a nominal speed of 3,000 RPM and a maximum speed of 4,600 RPM. The rotor has a moment of inertia of 0.00932 kg·m², and the motor generates up to 160.0 Nm maximum torque with 57.0 Nm continuous torque at standstill (100 K), requiring a continuous current of 34.9 A and permitting a maximum current of 137.7 A. Equipped with a single-turn optical encoder (EnDat2.1, 2048 signal periods), the unit possesses four pole pairs and a plain shaft. A KTY84 sensor enables independent temperature monitoring. The holding brake supplies 70 Nm torque, and the shaft design follows DIN 3760 - Design A to minimize backlash and noise and prevent liquid intrusion. The power connector is located on the B-side, and the overall design provides increased concentricity.

Why is the electrically released holding brake of 70 Nm useful in MSK101D-0300-NN-S2-BG2-RNNN servomotor?

The brake of MSK101D-0300-NN-S2-BG2-RNNN servomotor secures the load during power interruptions or standstill, preventing drift. It also enables safe maintenance stops without requiring external mechanical locks.

How does natural convection cooling benefit this motor over fan cooling?

It eliminates moving parts, reducing maintenance and failure points. It also ensures quieter operation and simpler integration in tight enclosures.

How does the MSK101D-0300-NN-S2-BG2-RNNN servomotor manage thermal limits during extended standstill with load?

The MSK101D-0300-NN-S2-BG2-RNNN servomotor natural convection cooling and thermal design allow a 57 Nm continuous torque at 100 K standstill without excessive heating. Appropriate duty cycles and ambient temperature management are still required.

How does increased concentricity design enhance dynamic response in this motor?

The better rotor-concentricity reduces imbalance and vibration, enabling faster accelerations and decelerations. It also contributes to smoother performance at high speeds.

How does MSK101D-0300-NN-S2-BG2-RNNN servomotor perform in robotics applications?

The high torque of 160 Nm, precise encoder feedback, and low vibration from increased concentricity make it excellent for robotic arms and axes. Its holding brake ensures safety during pauses or power failures in motion sequences.
