The Rexroth Indramat synchronous motor R911317817 (MSK071D-0300-NN-S2-UP2-RNNN) features a four-pole design and natural convection cooling. It supports a maximum speed of 3800 rpm with a continuous torque at standstill of 20.0 Nm (100 K) and a peak torque of 66.0 Nm. The motor operates within a 0–40°C ambient temperature and has a thermal time constant of 54 minutes. Key electrical parameters include a winding resistance of 1.26 Ω, winding inductance of 10,700 mH, and a torque constant of 2.12 Nm/A. It delivers a maximum current of 40.5 A and continuous current at standstill of 10.7 A (100 K). The output shaft is equipped with a keyway and sealing ring. The unit is fitted with an EnDat2.1 singleturn optical encoder offering 2048 signal periods and a rotatable electrical plug (240°). An electrically released holding brake (1.6 kg) provides 30 Nm holding torque at 0.94 A current draw.

Frequently Asked Questions

What advantage does an optical EnDat2.1 encoder provide in automation tasks?

The encoder ensures high resolution feedback for precise positioning and speed regulation. The system benefits from reduced drift and higher repeatability in closed loop control.

How does the rotatable connector improve cable management in compact machines?

The connector allows flexible orientation to route cables efficiently in tight spaces. The reduced cable strain increases reliability and lowers the risk of connection faults.

Why is increased concentricity valuable in synchronous servomotors?

The improved concentricity minimizes vibration and enhances shaft balance during high speed motion. The reduced mechanical runout increases lifespan of couplings and driven components.

What are the implications of drawing 40.5 A at peak operation?

The high peak current requires careful selection of drive and cabling. The system must be sized to manage thermal and electrical stresses during short bursts.

How does continuous torque at standstill benefit precision machinery?

The ability to hold torque without motion is essential in indexing tables and robotics. The machine can apply stable force while maintaining positional accuracy.
