Product Details

The Bosch Rexroth MSK040B-0450-NN-M1-UP0-NNNN is an advanced synchronous servo motor engineered for dynamic industrial control.

Recognized by material number (MNR) R911321452, this unit integrates a multi-turn absolute encoder (M1) with a robust keyed shaft design (P) for secure mechanical power transmission. Designed for seamless integration, it features a rotatable power connector (up to 270 degrees), facilitating easy AC 3 × 400–480 V wiring to the respective drive controller. With its 0450 winding configuration, it delivers high torque density and precise speed regulation up to 6,000 RPM.

Key Technical Highlights

✓ Shaft with Keyway (P): Unlike plain shaft models, this version features a keyway. This provides a positive mechanical lock, preventing slippage in high-torque or frequent reversing applications.
✓ Absolute Position Memory: The integrated high-resolution M1 encoder (EnDat interface) retains multi-turn position data even when powered down, optimizing machine restart times.
✓ Flexible Wiring (270°): The rotatable power connector significantly simplifies cable management in tight machine chassis spaces.
✓ Passive Thermal Management: Reliable IP65 housing combined with natural convection cooling eliminates the need for maintenance-prone external fans.

Frequently Asked Questions

Q: Why should I choose the Rexroth servo motor shaft with keyway (UP0 configuration)?

A: The keyed shaft (designated by the 'P' in the type code) provides a positive mechanical connection between the motor and the driven load. This is highly recommended for applications involving high torque transfer or frequent, sudden changes in rotational direction, where a plain shaft might slip.

Q: How does the Rexroth R911321452 power connector aid in installation?

A: The motor is equipped with a rotatable electrical connector that can turn up to 270 degrees. This design greatly enhances flexibility during installation, allowing technicians to route the AC power cables efficiently without stressing the connections or requiring excess space.

Q: Is battery maintenance required for the Indramat multi-turn absolute encoder on this unit?

A: The 'M1' photoelectric absolute encoder tracks position data precisely. Depending on the exact generation of the drive system it connects to, it generally eliminates the need for battery-backed reference runs, saving time during machine startups.
