The R911257553 (MDD093B-N-040-N2L-130PB1) is a Bosch Rexroth digital AC servomotor engineered for integration with digital drive controllers. It features a size code of 093, a length of 357 mm, and a centering diameter of 130 mm. The unit provides continuous standstill torque of 14.5 Nm and a theoretical maximum torque of 45.1 Nm (excluding the blocking brake). The motor includes a standard 8 x 7 x 40 keyway shaft per DIN 6885-A, a blocking brake rated at 11 Nm, and a shaft sealing ring to prevent debris and water ingress. Motor feedback is provided via digital servo feedback (DSF). Power and feedback connectors must be sourced separately. When installing, ensure radial and axial forces do not exceed rated limits, and reseat the shaft sealing ring if stored for more than two years. Excessive multi-axial stress on the shaft may cause fracture. The blocking brake augments hold performance but is not intended for personnel safety functions.

Frequently Asked Questions

How does the keyway shaft in MDD093B-N-040-N2L-130PB1 support performance?

The keyway shaft ensures a firm connection between motor and load. It reduces slippage while allowing efficient torque transfer.

What is the advantage of having a centering diameter of 130 mm in this motor?

The 130 mm centering diameter provides better stability and precise mounting. This minimizes vibration and improves smooth operational performance.

Do users benefit from the side B connector orientation?

Yes, the side B connector simplifies wiring in tight spaces. It improves installation flexibility and reduces cable management issues.

Why is digital servo feedback important in MDD093B-N-040-N2L-130PB1?

It ensures accurate motor positioning and real-time performance monitoring. This leads to smoother synchronization with drive controllers.

How does the 14.5 Nm continuous torque at standstill help in this motor?

It allows the motor to sustain force without rotation. This capability is vital in applications that need reliable load holding at zero speed.
