The Bosch Rexroth R911308357 (MSK071D-0450-FN-S1-UG2-NNNN) is an IndraDyn S synchronous servomotor featuring a plain shaft and integrated optical Hiperface singleturn encoder providing 128 signal periods per revolution. It operates with a winding code of 0450, requires a continuous current at standstill (100 K) of 17.6 A, and delivers 20.0 Nm continuous torque at standstill, with maximum ratings of 69.3 A and 66.0 Nm, respectively. This model includes an electrically released holding brake rated at 30 Nm, operates within 0–40 °C ambient temperature and up to 1000 m altitude, and utilizes liquid cooling. The IP65-rated standard housing is equipped with 240° rotatable power and feedback connectors; relative humidity can range from 5% to 95% (absolute 1–29 g/m³), and the winding inductance is 3,200 mH.

Frequently Asked Questions

How does liquid cooling improve servomotor performance in continuous duty applications?

The liquid cooling maintains stable thermal conditions during high load operation. The result is improved efficiency and longer service life of the motor.

What is the benefit of a rotatable 240° encoder connector during installation?

The adjustable connector simplifies cable routing in tight enclosures. The flexibility reduces stress on wiring and minimizes the risk of connection failures.

How does an optical encoder with multiturn capability enhance automation accuracy?

The optical feedback ensures precise position control across multiple revolutions. The multiturn function eliminates the need for external homing after power cycles.

Why is the absence of a holding brake sometimes advantageous in servomotor design?

The lack of brake reduces inertia and mechanical complexity. The simplified design improves responsiveness in dynamic positioning systems.

How does a shaft with keyway support industrial reliability?

The keyway provides secure torque transmission between motor and load. The secure fit prevents slippage under high torque conditions.
