The Bosch Rexroth MPN R911253832 (MDD090C-N-030-N2M-110GB0) is a digital servo motor designed for precision motion applications. It incorporates an integrated multiturn absolute encoder and digital servo feedback system, enabling precise speed and position control by a digital controller. The motor has a 24 mm plain shaft with a shaft seal, a standard 405 mm housing for natural convection or surface cooling, and a 140 mm flange with an 11 mm mounting hole diameter. It does not include a blocking brake and offers continuous torque of 10.4 Nm at standstill with a nominal speed of 3000 min⁻¹. The connection is via a connector on side B, and the centering diameter is 110 mm. This motor is intended for digital drive controller integration, with standard shaft and housing configurations.

Frequently Asked Questions

What dynamic behavior can I expect at nominal 3000 min⁻¹ speed?

At full speed, the motor exhibits lower generated torque (due to back-EMF) and the current demand rises; the controller must maintain proper flux weakening or current limits to sustain performance.

What real-world constraints does having “no blocking brake” impose?

Without a holding brake, the shaft cannot be locked mechanically at standstill—thus, driven loads must not self-rotate under gravity or external torque when powered off.

Which drive controllers are recommended or compatible with this motor (naming manufacturer and product code)?

The Bosch Rexroth DDC / MDD series drives (e.g. DDC + MDD digital servo drives) are designed to interface with the MDD090C-N-030-N2M-110GB0, leveraging its DSF feedback.

What lifetime or reliability factors are most critical in B2B deployments of this motor?

Bearing load, thermal cycling, and alignment stresses drive reduced life, so systems should minimize radial loads and maintain ambient temperature within spec to ensure long mean time between failures.

How does the integrated multiturn absolute encoder impact system startup and homing?

The encoder retains absolute position across power cycles, so the controller can resume motion without a full rehoming routine (if configured properly).
