Product Description:
The MDD090B-N-030-N2L-110GB0 is a synchronous servo unit manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts drive current into precisely regulated mechanical rotation for positioning or velocity loops in industrial automation. Its size 090 frame and length code B give it a mid-sized footprint suited for machine tools, printing lines, and packaging axes that demand repeatable motion. The motor is intended for closed-loop axes where stable torque production and repeatable speed regulation are required during continuous production cycles.
The mechanical interface uses a centering diameter of 110 mm, allowing accurate alignment to gearboxes or mounting flanges. The plain shaft is fitted with a shaft seal to limit lubricant loss and airborne contamination. During continuous holding conditions, the rotor can deliver 7.2 Nm of torque without exceeding thermal limits, while closed-loop operation through digital servo feedback provides the controller with high-resolution position data. For dynamic applications, the motor sustains a rated speed of 3000 rpm, balancing thermal loading and magnetic saturation at nominal drive voltage. Power and signal conductors terminate on a rear-mounted connector, which helps simplify cable routing in tight cabinets and keeps the installation compact when the motor is mounted close to machine frames.
Rotor mass is factory balanced to the Standard grade to minimize vibration across the full speed range. Cabling exits on Side B, placing the connections on the machine side opposite the load. The mating plug style is a sealed connector, which allows wiring without removing the cover. When power is removed, the axis relies on external restraints because the motor is supplied without a blocking brake. The shaft end is suited to direct coupling with clamping hubs. The housing remains standard without additional cooling fins, which supports installation inside ventilated electrical enclosures.
