The R911336741 (MSK100A-0450-NN-S1-BG0-NNNN) is an IndraDyn S synchronous servomotor designed for integration within motion control systems. It features a 100 size, length A housing with an IP65 rating and 2K epoxy resin coating for resistance to dust, water jets, diluted acids, alkalis, mineral oils, sewage, and water exposure. The unit includes a plain output shaft and sealing ring to prevent fluid ingress and is equipped with a single-turn optical encoder using the Hiperface interface, providing 128 signal periods for precise speed and position feedback. The motor operates via natural convection cooling, features a B-side power connector, and supports dual temperature monitoring. Its electrical specifications include a winding code 0450, a continuous current at standstill of 13.6 A (100 K), continuous torque at standstill of 17.0 Nm (100 K), maximum current of 54.0 A, maximum torque output of 54.0 Nm, and winding inductivity of 7,800 mH. No holding brake is included in this model.

Frequently Asked Questions

How does natural-convection cooling on MSK100A-0450-NN-S1-BG0-NNNN affect duty cycle and enclosure planning?

The natural convection removes fans from the BOM for lowering maintenance while relying on surface area and airflow. Its continuous torque is 17 Nm @100 K against thermal time constants during cyclic motion.

How does the 7,800 mH winding inductivity in MSK100A-0450-NN-S1-BG0-NNNN influence current ripple and servo stability?

The higher inductivity filters PWM ripple, reducing torque ripple and audible artifacts during dynamic profiles. It also relaxes current-loop bandwidth demands for improving phase margin, while tune carefully to preserve step response.

Why specify a plain-shaft interface on MSK100A-0450-NN-S1-BG0-NNNN for precision motion?

The plain shaft mates cleanly with zero-backlash clamping couplings for minimizing torsional windup and alignment stack-up. It simplifies hub selection while supporting accurate cyclic positioning and smooth load transitions.

How should the “17.0 Nm at standstill, 100 K” rating on MSK100A-0450-NN-S1-BG0-NNNN be interpreted for vertical-axis or tension duties?

It’s the continuous holding torque at the specified winding temperature with adequate cooling. It incorporates field-oriented control and current limiting for transient spikes.

What acceleration headroom does 54.0 A / 54.0 Nm give MSK100A-0450-NN-S1-BG0-NNNN in indexing or pick-and-place tasks?

The peak current and torque enable rapid speed changes and disturbance rejection during short moves. It is important to validate peak-time limits in the drive and ensure mechanical couplings tolerate the commanded jerk and torsional oscillations.
