Product Description:

The MDD090A-N-020-N2L-110GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, it converts electrical energy into precisely regulated mechanical rotation while also supplying position data to the control loop. This integrated feedback arrangement lets the drive monitor rotor movement without a separate external encoder. It also helps the control system respond quickly to load changes during start, stop, and reversal. The motor is suited for printing presses, pick-and-place gantries, and similar machinery that requires accurate speed regulation, repeatable positioning, and a compact installation footprint.

At a nominal speed of 2000 rpm, the rotor reaches the synchronous speed used in many Rexroth drive applications. Under standstill, it sustains 3.7 Nm of continuous torque, which supports holding and indexing duties without excessive heat buildup. When the controller is disabled, an integrated brake applies 11.0 Nm to hold vertical or safety-related loads. Position data is generated by Digital servo feedback (DSF), giving the drive fine-resolution signals for closed-loop velocity and position control. The mechanical output uses a plain shaft, which supports clamping or press-fit connections where low backlash is important.

Standard balancing helps reduce residual vibration during acceleration and reversing. A 110 mm centering diameter keeps the motor aligned with the mating machine surface for accurate installation. Power and feedback connectors exit to the right, which can simplify cable routing when multiple axes are mounted close together. This layout is useful in dense machine frames where motor depth and cable bend space are limited. A shaft seal helps keep coolant and lubricant away from the bearing area. The housing is built for IP65 protection, and the short A housing length helps save space in shallow machine layouts.
