Product Description:

The MDD090B-N-030-N2L-110GR0 servo motor is manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for digital drive controllers, it supplies commanded torque and speed to machine-tool axes, packaging lines, and material-handling modules that rely on closed-loop electric motion. The motor is suited for axes that need repeatable starts, stops, and speed changes, and its synchronous design helps the drive maintain accurate positioning when process loads vary during normal machine cycles. This supports stable motion in equipment where smooth response and predictable control are more important than passive load holding at standstill.

Within the B-length housing, the unit provides a continuous standstill torque of 7.2 Nm, allowing it to hold loads without overheating when the rotor is locked. During motion, it reaches a nominal speed of 3000 rpm, aligning with mid-range inverter outputs for stable throughput. A centering diameter of 110 mm aligns the stator face to gearboxes and frames, which helps limit radial runout. Position and velocity data are returned through digital servo feedback (DSF), enabling the controller to correct current loops in real time. Power and signal conductors exit through a connector on the right side, which helps simplify cable routing when multiple motors share one panel. The motor is supplied without a holding brake, reducing mass where external dynamic or mechanical braking is already present, and it uses a standard housing with a sealed connector interface.

A plain shaft transmits torque to couplings while an internal shaft seal helps keep coolant or dust away from the bearings in enclosed machine spaces. The motor has a frame size of 090, and the rotor-stator stack uses length code B, balancing electromagnetic density with overall length for medium-power axis duties. Internally, standard balancing limits residual vibration so the rotor can accelerate smoothly without additional tuning, while the shaft end is present only on side A and leaves side B available for encoder components or handling fixtures.
