The R911318431 (MSK101D-0300-NN-S2-AP0-RNNN) is a Bosch Rexroth IndraDyn S synchronous servomotor featuring a maximum speed of 3000 RPM and a maximum torque of 160.0 Nm. The motor employs natural convection cooling, is equipped with a KTY84 temperature sensor, and utilizes an independent temperature model system. It features an IP65 rating for dust and water resistance. The unit has four pole pairs, a thermal time constant of 100.0 minutes, and a plain output shaft with a sealing ring. The optical singleturn encoder operates at 2048 signal periods resolution with EnDat2.1 interface, offering ±20 arcseconds system accuracy. The shaft has a keyway, and the design ensures increased concentricity as per DIN 42955. Electrical specifications include a continuous current at standstill (100 K) of 34.9 A, a continuous torque at standstill of 57.0 Nm, a maximum current of 137.7 A, and a winding inductivity of 3,200 mH. The power connector is positioned on the A side and the model does not include a holding brake.

Frequently Asked Questions

Why is a keyway shaft chosen in MSK101D-0300-NN-S2-AP0-RNNN servomotor instead of a smooth shaft?

The keyway of MSK101D-0300-NN-S2-AP0-RNNN servomotor ensures positive torque transmission without slippage in reversing cycles. It simplifies coupling in high-torque duty cycles compared to clamping only.

In what way does the EnDat 2.1 singleturn encoder with 2048 periods aid precision?

It delivers high-resolution absolute position feedback per revolution. That allows sub-µm closed-loop interpolation and precise trajectory tracking.

How long is the bearing lifetime when load limits are respected?

The answer: When radial/axial loads and temperature limits are respected, the bearing life L₁₀h is about 30,000 operating hours.

How does the 3,200 mH winding inductivity improve control stabilityof MSK101D-0300-NN-S2-AP0-RNNN servomotor?

The high inductance of MSK101D-0300-NN-S2-AP0-RNNN servomotor smooths current ripple and filters high-frequency switching noise. It enhances servo loop stability under fast dynamic loads.

What is the advantage of using an A-side power connector in MSK101D-0300-NN-S2-AP0-RNNN servomotor?

It standardizes wiring and ensures plug-and-play compatibility with IndraDrive systems. It reduces field wiring errors and improves commissioning speed.
