Product Description:

The MDD090A-N-030-N2L-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for applications that use digital drive controllers. It belongs to the MDD Synchronous Motors series, which is intended for precise position and speed control in automated machinery. As a motor for industrial automation, it converts commanded electrical energy into rotary motion so axes on packaging, handling, or processing lines can be moved accurately and repeatably.

The centering flange on this model measures 110 mm, giving a reference diameter for mounting concentricity in gearboxes or mechanical frames. At standstill, it can deliver 3.7 Nm of continuous torque, indicating the load it can hold without overheating when the shaft is locked. During regular operation, the rotor can reach a nominal speed of 3000 rpm, which aligns with drive output frequency and the motor’s pole count to provide stable synchronous rotation. Power and feedback conductors exit on side B, so cabinet layouts must leave clearance on that face. A plug-in connector style termination simplifies installation by allowing preassembled cables to be attached without hard-wiring.

Position feedback is handled through digital servo feedback, enabling high-resolution velocity loops in the drive. The motor is shipped without a blocking brake, so any static holding duty must be addressed by external clamps or torque from the drive itself. Protection against lubricant ingress is provided with a shaft seal, which helps extend bearing life in environments where oil mist or dust may be present. A plain shaft allows the use of couplings or pulleys that match the load inertia. Standard dynamic balancing and a standard housing help reduce vibration while keeping the motor compact, and the A-length frame within the 090 size range helps match motor inertia to small- to mid-mass loads without oversizing the drive components.
