The R911326890 (MSK071D-0300-NN-M2-UG0-RSNN) is a Bosch Rexroth IndraDyn S synchronous servomotor, designed for applications requiring precise rotational positioning, such as rotary main drives and servo axes. This unit, with motor size 071 and motor length D, uses winding code 0300 and employs a multiturn absolute optical encoder with EnDat 2.1 interface, resolution of 2048 signal periods, and ±20 angular seconds accuracy, allowing position detection across 4,096 mechanical revolutions. The motor offers a maximum speed of 3,800 rpm, continuous torque at standstill of 20.0 Nm (100 K), continuous current at standstill of 10.7 A (100 K), maximum current of 40.5 A, and maximum torque of 66.0 Nm. It is equipped with a plain output shaft and a sealing ring, features two temperature sensors, and supports natural convection cooling. The rotor inertia is 0.00255 kg·m², and the encoder connector is rotatable 240°. The design supports increased concentricity and explosion protection. No holding brake is included.

Frequently Asked Questions

How does natural convection cooling affect motor installation in confined spaces?

The motor requires sufficient airflow around its surface for heat dissipation. The installer must avoid sealing it in enclosures without ventilation to maintain performance.

What practical advantage does a rotatable encoder connector provide?

The connector allows flexible cable routing during installation. The installer can adjust its position within 240 degrees to simplify wiring in tight layouts.

Why is an optical encoder with multiturn absolute technology beneficial in automation?

The encoder retains position data even after power loss. The machine resumes operations without needing to rehome or recalibrate.

How does high winding inductivity impact drive selection?

The inductivity requires drives that can manage slower current changes. The result is smoother torque delivery and reduced ripple in sensitive processes.

Why is explosion protection design important for certain industries?

The design allows safe operation in environments with flammable gases or dust. The motor reduces ignition risk and meets compliance standards.
