The R911325414 (MSK071D-0450-NN-M2-UG1-RNNN) is a synchronous servomotor developed by Rexroth Indramat, featuring natural convection cooling and a D-length 071-size frame. It utilizes a brushless design and is equipped with a multiturn absolute optical encoder (EnDat2.1 interface, 2048 signal periods, rotatable 240° connector). The motor integrates an electrically released holding brake with a holding torque of 23 Nm (24 V, 0.79 A), and employs grease-lubricated ball bearings rated for up to 30,000 operating hours. The MSK071D series supports continuous standstill torque of 20 Nm at 17.6 A (100 K), with maximum values of 66 Nm torque and 69.3 A current. The shaft is plain and the unit is designed for ambient temperatures up to 50°C and elevations up to 1000 m.

Frequently Asked Questions

How does natural convection cooling affect motor installation?

The cooling method allows operation without external fans or liquid cooling systems. The design simplifies installation in environments where compactness and low maintenance are required.

What is the practical benefit of having a multiturn absolute encoder?

The encoder tracks shaft position over multiple revolutions without battery backup. The feature ensures accurate positioning after power cycles and eliminates the need for homing sequences.

How does a plain shaft design impact machine integration?

The plain shaft enables flexible coupling options and supports direct drive connections. The design minimizes backlash and is well suited for precision applications.

How does torque capability affect application performance?

The available torque ensures stable continuous operation under load. The higher peak torque enables quick acceleration and dynamic response during demanding cycles.

How does continuous current demand influence drive selection?

The current rating determines the required capacity of the drive amplifier. The correct pairing ensures efficiency and prevents overheating during sustained operation.
