Product Description:

The MDD090A-N-030-N2M-110GL2 is a synchronous servo motor built by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Delivered as a motor for digital drive controllers, it converts controlled three-phase current into rotary motion for precision positioning and stable velocity control in automated tooling, packaging machines, and handling equipment. Integrated feedback channels allow the controller to monitor rotor movement continuously, so the axis can follow commanded motion paths under changing mechanical load. Its sealed housing also supports use near the machine or inside protected enclosures where space is limited.

It develops 3.7 Nm of continuous torque at standstill, while the rotor can attain a rated speed of 3000 rpm during rapid feed moves. A centering diameter of 110 mm aligns the flange with tight concentricity, and the motor’s power and encoder connectors on the left side simplify panel wiring when the cabinet is located on that side of the axis. Position data is carried through Digital servo feedback (DSF), giving the inverter high-resolution incremental information for closed-loop control. The standard housing uses a connector-based power interface, includes a single-ended shaft seal, has motor length code A, and omits a side-B shaft end to keep the package compact.

An internal brake provides 11.0 Nm of torque, so the load stays fixed when the controller is disabled. Absolute position is maintained by the integrated multi-turn absolute encoder, which counts multiple revolutions and removes the need for homing after power is restored. Power is transmitted through a plain shaft, which accepts clamp couplings, and vibration is limited by the motor’s standard balancing grade. Size class 090 is paired with the short A-length stator, allowing the motor to fit mid-frame machines that require continuous-duty servo operation.
