The R911373166 (MSK100A-0300-NN-S3-BP0-NNNN) is a synchronous servomotor designed for industrial applications, featuring a motor size of 100 and length 'A'. It incorporates a single-turn, capacitive Hiperface encoder with a resolution of 16 signal periods, supports natural convection cooling, and places its power connector on the B-side. The shaft includes a keyway and sealing ring. It meets IP65 protection standards and provides an insulation class of 155. The motor achieves continuous current at standstill (100 K) of 11.6 A and torque of 17.0 Nm, with a maximum current of 45.9 A and peak torque of 54.0 Nm. The unit weighs 23 kg, has a moment of inertia of 0.01100 kgm², uses winding code 0300, and operates from -20 to +80°C up to 1,000 meters altitude. A four pole-pair configuration, 40-micron anti-corrosion coating, winding inductivity of 11,200 mH, and no holding brake are also specified. Sound pressure is maintained below 75 dB.

Frequently Asked Questions

Why is natural-convection cooling selected, and what are the installation implications?

Natural convection eliminates external fans and reduces service parts, but requires clear airflow and ambient operation within 0–40 °C. Keep vertical convection paths unobstructed; for higher continuous loads, Rexroth offers retrofit blower units.

How do IP65 construction and the shaft sealing ring benefit MSK100A-0300-NN-S3-BP0-NNNN in harsh cells?

The IP65 coverage of housing, shaft and connectors resists dust and water jets when properly mated. Its keyway shaft with sealing ring limits lubricant loss and ingress for extending bearing life in washdown-adjacent packaging or machining environments.

What torque and current limits define axis sizing for MSK100A-0300-NN-S3-BP0-NNNN?

The winding delivers 17.0 Nm continuous at 100 K with 11.6 A and 54.0 Nm peak at up to 45.9 A. Its headroom values suit fast index tables, delta pickers and rapid C-axes.

What installation advantages come from the B-side power connector on MSK100A-0300-NN-S3-BP0-NNNN?

The type-code “B” indicates the power flange on the B-side for easing cable routing along machine frames and minimizing bend radius conflicts near gearboxes. It also helps segregate feedback and power harnessing.

How do ambient temperature and altitude constraints influence performance of MSK100A-0300-NN-S3-BP0-NNNN?

The rated operation is 0–40 °C and up to 1,000 m; within this envelope the nameplate data apply without derating. Its thermal margins diminish demineshes beyond these limits and continuous torque may require recalculation.
