The R911321318 (MSK075E-0300-NN-M2-UG1-RNNN) is a Bosch Rexroth IndraDyn S synchronous servomotor with frame size 075, motor length E, and winding code 0300. It is equipped with a multiturn absolute optical encoder providing 2048 signal periods and features an EnDat 2.1 interface. The motor includes a plain shaft with a specialized seal for dust protection and a 240-degree rotatable power connector. Cooling is provided by natural convection, with an optional fan-assisted configuration. Electrical specifications include a continuous standstill current of 15.6 A, maximum current of 63.9 A, continuous standstill torque of 23.0 Nm, maximum torque of 88.0 Nm, and winding inductivity of 4.460 mH. The IP65 enclosure offers high ingress protection, and an optional electrically-released 24V DC holding brake delivers 23 Nm torque. Design features include enhanced concentricity and reduced shaft run-out.

Frequently Asked Questions

What advantage does the EnDat 2.1 encoder in the MSK075E-0300-NN-M2-UG1-RNNN provide?

The EnDat 2.1 encoder ensures precise digital feedback and quick data transmission. This enhances synchronization and positioning accuracy in automated motion systems.

Why is increased concentricity important in the MSK075E-0300-NN-M2-UG1-RNNN motor design?

Increased concentricity minimizes mechanical vibration and improves shaft alignment. This leads to smoother motion and longer bearing life in high-precision equipment.

How does the electrically-released holding brake benefit system safety?

It keeps the motor shaft locked when power is off and releases only when energized. This feature enhances operational safety during machine maintenance or emergency stops.

What is the purpose of using a plain shaft in the MSK075E-0300-NN-M2-UG1-RNNN?

A plain shaft allows flexible coupling with various mechanical setups. It’s particularly useful for customized integrations in automation and process control systems.

How does the 23 Nm holding brake torque impact machine performance?

This torque value ensures reliable load holding in vertical or dynamic applications. It supports precise control during power loss or when stationary positioning is required.
