The R911315325 (MSK100B-0300-NN-M2-AG0-RNNN) is an IndraDyn S synchronous servomotor from Bosch Rexroth's MSK series. It features a compact construction with increased concentricity and a plain shaft designed for coupling via clamping elements. The motor uses natural convection for cooling and incorporates a KTY84 thermal sensor for thermal monitoring. Technical specifications include a winding resistance of 0.43 Ohms at 20°C, winding inductance of 5,500 mH, and a voltage constant of 108.5 V/min-1. Maximum speed is 4,500 RPM, with continuous current at standstill (100 K) of 20.5 A and continuous torque at standstill of 33.0 Nm. The maximum current is 78.3 A, and maximum torque is 102.0 Nm. An optical EnDat2.1 multiturn absolute encoder with 2048 signal periods provides feedback. Shaft run-out and axial run-out conform to DIN 42955 requirements. The enclosure rating is IP65, ensuring resistance to dust and water spray ingress.

Frequently Asked Questions

Why does MSK100B-0300-NN-M2-AG0-RNNN feature 2048 signal periods encoder?

The encoder resolution improves interpolation accuracy. Systems achieve extremely fine positioning, supporting demanding CNC contouring or micro-stepping robotics applications.

How does MSK100B-0300-NN-M2-AG0-RNNN improve shaft alignment reliability?

Its increased concentricity design minimizes mechanical runout. Couplings maintain balance under rotation, reducing wear and vibration across connected assemblies.

Why is 20.5 A continuous current valuable in MSK100B-0300-NN-M2-AG0-RNNN?

This current supports sustained torque delivery. The motor run long duty cycles while maintaining thermal stability under demanding load requirements.

How does MSK100B-0300-NN-M2-AG0-RNNN benefit from EnDat2.1 interface?

EnDat2.1 combines position data with diagnostics. Controllers detect errors early, enhancing reliability and simplifying predictive maintenance schedules.

Why is natural convection cooling advantageous in MSK100B-0300-NN-M2-AG0-RNNN?

Passive heat dissipation removes thermal loads quietly. Maintenance requirements drop, and system noise remains lower.
