The R911321645 (MSK100A-0200-NN-S2-BP0-RNNN) is an IndraDyn S synchronous servomotor engineered for precise position and speed control in industrial automation environments. It features four pole pairs, a shaft with keyway, and utilizes natural convection for cooling. The motor is constructed with class 155 thermal materials and supports an ambient temperature range from 0 °C to 45 °C. Key electrical specifications include a continuous current at standstill of 10.4 A, maximum current of 41.4 A, continuous torque at standstill of 17.0 Nm, and maximum torque of 54.0 Nm. It reaches a maximum speed of 4400 rpm with a winding inductivity of 13,900 mH. The integrated optical encoder (EnDat2.1, singleturn, 2048 signal periods) provides high-precision feedback. The unit weighs 23 kg and does not include a holding brake. Design features include increased concentricity, protection against fluid ingress, and suitability for high speed start-stop applications due to its low rotor inertia.

Frequently Asked Questions

How does the EnDat 2.1 single-turn encoder in MSK100A-0200-NN-S2-BP0-RNNN improve servo precision and signal integrity?

The optical encoder provides absolute position per revolution with 2048 signal periods and 1 Vpp incrementals for enabling fine interpolation and stable loop tuning. Its EnDat 2.1’s mixed analog/digital scheme mitigates interference and supports controller diagnostics.

How does increased concentricity of the rotor/shaft benefit MSK100A-0200-NN-S2-BP0-RNNN installations?

Its tighter runout reduces cogging-related ripple and mechanical imbalance for improving velocity smoothness and surface finish on machining or web-handling processes. It also eases coupling alignment tolerances in precision kinematic chains.

What are the integration implications of the B-side power connector on MSK100A-0200-NN-S2-BP0-RNNN?

The B-side orientation simplifies cable routing on certain gantry or vertical axes for reducing bend stress and electrical noise coupling to feedback lines. It assists compact machine layouts frequently seen in automation and forming cells.

How does the shaft-with-keyway design impact coupling choices for MSK100A-0200-NN-S2-BP0-RNNN?

Its keyed shaft supports backlash-free clamp hubs and standardized taper-lock pulleys for easing torque transmission up to the motor’s 54.0 Nm limit. It’s a familiar interface for retrofit machine tools and conveyors.

Why is a single-turn encoder acceptable on MSK100A-0200-NN-S2-BP0-RNNN for multi-axis lines?

Its homing restore absolute machine position after power cycles for making single-turn feedback sufficient. Its EnDat 2.1 maintains high resolution within one revolution for accurate contouring.
