The Bosch Rexroth synchronous servo motor R911343220 (MSK071D-0300-NN-M2-UP1-RNNN) is a four pole-pair model from the IndraDyn S series, designed for applications requiring precise speed and position control. It uses an optical EnDat 2.1 multiturn absolute encoder with 2048 signal periods and a rotatable connector (240°). The motor incorporates a KTY84 temperature sensor and independent thermal modeling for overload protection. Key features include IP65 protection, natural convection cooling, a shaft with keyway, 23 Nm electrically-released holding brake, continuous standstill torque at 100 K of 20.0 Nm, maximum torque of 66.0 Nm, winding inductivity of 10,700 mH, and maximum current of 40.5 A.

Frequently Asked Questions

How does natural convection cooling affect motor maintenance needs?

The absence of fans eliminates moving parts that may fail. The motor requires less frequent servicing and operates with reduced noise.

What is the advantage of having a rotatable 240° encoder connector?

The connector allows flexible cable routing in tight installations. The feature simplifies integration into control cabinets or machines.

How does the multiturn absolute encoder improve machine control accuracy?

The encoder stores position data across multiple revolutions without external batteries. The feature ensures precise startup positioning even after power loss.

What benefits does a shaft with keyway provide compared to a plain shaft?

The keyway ensures reliable torque transmission between motor and load. The feature minimizes slippage under high dynamic loads.

How does the electrically released holding brake with 23 Nm torque help in automation systems?

The brake secures load position when the motor is de-energized. The feature is critical for vertical axes and safety-related operations.
