The Bosch Rexroth Indramat MDD093D-N-040-N2M-110GB1 from the MDD Synchronous Motors series is a high-precision motor for digital drive controllers featuring a continuous torque at standstill of 24.0 Nm and a blocking brake with a holding torque of 11 Nm. It incorporates an integrated multiturn absolute encoder and supports Digital servo feedback (DSF) for accurate positioning. The motor’s standard-balanced housing and plain shaft with shaft seal ensure durability, while its 110 mm centering diameter and side B connector connection direction simplify mechanical and electrical integration. Rated for a nominal speed of 4000 min⁻¹ and using motor length code D, this unit delivers reliable performance in demanding applications.

Frequently Asked Questions

What advantages does the integrated multiturn absolute encoder provide versus a separate encoder?

It allows lossless position retention on power-down and eliminates the need for external homing after each startup. The drive reads absolute rotor position directly, speeding commissioning and reducing wiring complexity.

How does the “standard-balanced housing” influence vibration and rotor stability in high-speed use?

It ensures that unbalance is within acceptable limits, reducing mechanical resonance and runout at high rpm. This is critical when coupling to precision loads (e.g. spindles, linear slides) to maintain smooth motion.

What are the integration implications of the 110 mm centering diameter and side B connector orientation?

The 110 mm centering diameter matches standard servo mount flanges, simplifying mechanical alignment. The “side B” connector direction dictates cable routing and may limit proximity to adjacent components, so ensure clearance and bend radius.

To what degree does the 4000 min⁻¹ nominal speed restrict usable torque bandwidth?

The motor’s inductance, winding resistance, and encoder latency define a cutoff frequency; above that, torque falls off. In practice, torque amplitude drops at high frequency, so ensure your control bandwidth is well under that mechanical speed limit.

How does using this motor in a B2B OEM context (e.g. packaging or robotics) impact lifecycle support and spare strategy?

Because Bosch Rexroth MDD-series motors are industrial standard, spare units and repair modules are accessible globally. For critical machines, keeping a spare motor plus calibration backup file avoids long downtime.
