MDD093D-N-020-N2L-130PA2
MDD Synchronous Motors
The Bosch Rexroth Indramat MDD093D-N-020-N2L-130PA2 from the MDD Synchronous Motors series is a robust motor for digital drive controllers featuring a motor size of 093 and a motor length code of D. This unit delivers a continuous torque at standstill of 24.0 Nm and integrates a holding brake with a holding brake torque of 22 Nm for secure positioning. It is manufactured with standard balancing and housing, and features a shaft type keyway with shaft seal. With a nominal speed of 2000 min⁻¹, a centering diameter of 130 mm, and side A connection direction via connector, it supports digital servo feedback (DSF) and is supplied without a side B shaft end for streamlined integration.

Frequently Asked Questions
Does the Bosch Rexroth Indramat MDD093D-N-020-N2L-130PA2 need homing after power-up with DSF?
Yes—DSF is relative, so the axis must be re-homed after power loss; the DSF+MTG variant retains absolute multi-turn position. DSF resolution/accuracy is 2,097,152 inc/rev and ±0.5′, useful for tight positioning.
How well is the motor protected in coolant-spray areas?
With a shaft seal, the shaft zone achieves IP65 (without it, IP50), and both power and feedback connections are IP65; cooling/blower parts are lower (IP24/IP44), so avoid direct jets there. Plan splash zones accordingly.
Can the built-in brake be used as an emergency stop on a vertical axis?
It’s a holding/parking brake, not a service brake; repeated dynamic stopping will wear it quickly. Safety-critical applications need additional measures (e.g., secondary brake) and the drive can be parameterized for fault-clamp behavior.
When should I add a blower or consider liquid cooling?
The MDD supports natural convection, and MDD093 allows optional axial/radial blowers for higher thermal loads; use them for sustained S6 duty or elevated ambient. For extreme heat flux, an MDD liquid-cooled variant exists.
How “plug-and-play” is the feedback connection during commissioning?
A 12-pin feedback socket is standard, and the feedback unit stores motor parameters that the drive reads at power-up to prevent misconfiguration. This simplifies wiring and commissioning.
