Product Description:

Bosch Rexroth Indramat supplies the MDD090A-N-030-N2M-130GA0 as part of the MDD Synchronous Motors series. This motor for digital drive controllers converts electrical energy from an inverter into rotary motion for automation axes that require coordinated velocity and position control. Within an installation, it couples directly to the driven load so the servo drive can regulate position and torque through electronic feedback. Its compact construction supports space-conscious machine layouts and maintains compatibility with standardized Rexroth cabling during demanding duty cycles.

The motor produces a continuous stall torque of 3.7 Nm, giving predictable holding force when the shaft is energized but not turning. The motor has a nominal speed of 3000 rpm, so the drive can reach common industrial operating speeds without mechanical gearing. The flange incorporates a centering pilot of 130 mm, which aligns the housing concentrically with the machine frame to help minimize runout. Power and feedback conductors exit on side A, which can simplify cable routing when the unit is mounted at the rear of a slide or gantry. A sealed circular connector supports quick connection while maintaining shielding continuity against electrical noise.

Dynamic position data is returned to the controller through digital servo feedback (DSF), generated by an integrated multi-turn absolute encoder that supports position tracking across multiple revolutions without a homing routine. The motor is supplied without a blocking brake, so the shaft can coast after power removal and any holding function must come from the machine or drive system. The output uses a plain shaft with a factory-installed shaft seal to support standard friction couplings while limiting lubricant migration. The motor also uses standard balancing and a standard housing, and its length code A with size 090 suits compact servo modules.
