The R911379707 (MSK071D-0300-FN-S2-UG0-RNNN) is a synchronous servomotor from the MSK071D series with liquid cooling and an IP65 protection rating. It operates reliably at altitudes below 1000 meters, with permissible ambient temperatures from 0 to +40°C and transit temperatures between -20 and +80°C. The motor features a plain shaft, no holding brake, and a weight of 18 kg. Key electrical characteristics include a winding resistance of 1.26 ohms at 20°C, winding inductivity of 10,700 mH, maximum current of 40.5 A, continuous current at standstill of 10.7 A (100 K), and maximum torque of 66.0 Nm, with continuous torque reaching 20.0 Nm at 100 K. It is fitted with a single-turn EnDat2.1 optical encoder (2048 signal periods), a rotatable (240°) encoder connector, and a 54-minute thermal time constant. The design emphasizes increased concentricity, emits less than 75 dB, and achieves speeds up to 3800 rpm.

Frequently Asked Questions

How does the MSK071D-0300-FN-S2-UG0-RNNN sustain efficiency under heavy thermal load cycles?

It uses liquid cooling to maintain thermal equilibrium. This ensures stable torque output and protects winding insulation during prolonged duty operation.

How precisely does this model deliver feedback in closed-loop control systems?

It employs an optical encoder with 2048 signal periods and EnDat2.1 interface. This allows high-fidelity position detection and repeatable servo accuracy.

How does the MSK071D-0300-FN-S2-UG0-RNNN achieve smooth electromagnetic behavior under variable currents?

Its winding inductivity of 10,700 mH stabilizes phase current transitions. This minimizes torque ripple and enhances smooth speed regulation.

What benefit does the rotor and shaft configuration provide in alignment-critical systems?

A plain shaft with increased concentricity improves mechanical balance and reduces radial runout. This enhances bearing life and motion precision.

How does the absence of a holding brake affect integration in servo applications?

The motor is built without a holding brake, requiring an external brake where static holding is needed. This design supports flexible motion architectures.
