Product Description:

The MDD090C-N-020-N2L-110PB0 is a synchronous servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. As a motor for digital drive controllers, it translates commanded current into controlled rotary motion for positioning tasks in automated lines, packaging cells, and material-handling stations. The 090 frame and a standard housing let the unit fit medium-power axes where closed-loop control and moderate thermal load are expected.

During continuous stall conditions, the rotor can hold 10.4 Nm of torque, providing static force for presses or vertical loads without losing synchronization. Under rated excitation, it reaches a nominal speed of 2000 rpm, matching drive stages that favor high torque over velocity. Mechanical centering is aided by a 110 mm pilot diameter, simplifying coaxial alignment with gearboxes or couplings. Dynamic balance follows the manufacturer's standard grade, limiting residual vibration at high rpm. Power and feedback conductors exit on the rear-right face because the connection hardware is mounted on Side B, and a sealed Connector interface provides a secure connection without disturbing conduit entries.

The housing finish is standard cast aluminum and protects internal laminations while allowing convection cooling. Feedback to the drive is supplied through digital servo feedback, enabling absolute position capture with minimal wiring. Length designation C indicates the active stack height, and size code 090 corresponds to the stator outer diameter. The model is built without a blocking brake, so external clamping devices must be used on gravity axes. A permanent shaft seal helps prevent lubricant egress, and the keyway shaft supports keyed couplings while the design omits a second shaft extension on side B to conserve space in inline layouts.
