Product Description:

The MDD090B-N-020-N2M-110GB0 is a synchronous AC servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, the unit supplies precise speed and position control to automated conveyors, pick-and-place modules, and indexing tables. This layout is commonly used where accurate starts, stops, and speed holding are required across repeated cycles. Its synchronous design supports repeatable servo response during changing load conditions. Standard rotor balancing limits vibration, and a compact B-length frame eases cabinet or machine-side integration. A plain shaft without a secondary shaft end passes torque directly to couplings or gearboxes while the standard housing withstands typical factory airborne contaminants.

The motor can sustain a continuous stall torque of 7.2 Nm, giving a clear static load limit when the shaft is energized but motionless. During dynamic operation, it reaches a nominal speed of 2000 rpm, delivering stable velocity regulation across the working band. A centering pilot of 110 mm aligns the flange on mating machine frames and keeps radial runout low. Power, brake, and feedback lines exit through a single connector, and these terminals are oriented toward the rear on the mounting face because the build uses side B cabling. Rear-oriented cabling can also help keep the connection area clear of nearby machine hardware. The rigid plain shaft helps reduce resonance so encoder signals remain stable at high-gain settings.

Feedback quality is enhanced by its digital servo feedback channel, which streams absolute position data from the integrated multi-turn absolute encoder directly to the controller every cycle. Because the unit ships without a blocking brake, holding at power-off requires drive torque or an external clamp. A fitted shaft seal keeps lubricants in and airborne coolant mist out, helping protect internal components during long duty cycles. This combination suits repetitive motion tasks that rely on accurate position feedback and a sealed shaft interface.
