The Bosch Rexroth MPN R911374585 (MSK075E-0450-NN-M1-UP2-NNNN) is an IndraDyn S synchronous servomotor designed for use in hazardous environments as defined by ATEX 94/9/EC directives. This motor features an optical multiturn absolute encoder using a Hiperface interface with 128 signal periods, and employs natural convection cooling. The encoder connector is rotatable by 240°. The output shaft is designed without a keyway. An electrically-released holding brake provides 30 Nm of torque. The unit reaches a continuous current of 15.6 A and continuous torque of 23.0 Nm at 100 K standstill, with a maximum current rating of 63.9 A and a maximum torque of 88.0 Nm. Winding inductivity is 4,460 mH. Proper grounding is required for safe operation, and commissioning should only commence after securing the grounded conductor.

Frequently Asked Questions

Why does natural convection cooling lower long-term system maintenance needs?

The passive design operates without mechanical fan components. Reduced moving parts minimize potential failure points and extend operational service intervals in industrial environments.

How does the multiturn encoder enhance coordination in multi-axis motion groups?

Stored rotational data allows precise axis synchronization over multiple cycles. System controllers maintain accurate alignment, even during asynchronous power interruptions or resets.

Why is 4,460 mH inductivity beneficial for electronic drive protection?

High inductivity absorbs voltage spikes generated by rapid load switching. Electrical surges are neutralized, reducing drive stress and preventing transient feedback distortion.

How does the keyed shaft structure support consistent torque application under shock loading?

The keyway interlocks with coupling components under pressure fluctuations. Rotational alignment remains stable, preserving mechanical balance during sudden directional reversals.

What performance advantage does the 0450 speed code provide in dynamic control tuning?

The speed index matches torque-to-speed characteristics effectively. Control systems achieve smoother velocity transitions and better thermal predictability under fluctuating workloads.
