Product Description:

The MDD090C-N-020-N2L-130GA1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for use with digital drive controllers, supplying precise torque and speed control to automated machinery, transfer lines, and positioning modules in industrial plants. Integrated feedback and an internal brake help keep an axis stable when the controller is disabled, which supports repeatable motion during indexing, feed control, and point-to-point positioning. Because the feedback device is built into the motor, the connected drive can monitor rotor position continuously and correct small deviations before they affect path accuracy.

Mounting alignment is simplified by a centering diameter of 130 mm, which helps the flange seat squarely against machine housings. Power and feedback cabling exit on side A, an arrangement that can simplify routing when the motor is installed in compact frames. The electrical interface uses a keyed connector, so the housing does not need to be opened for normal cable attachment. During continuous duty at standstill, the motor delivers 10.4 Nm of torque for static holding or low-speed feed motion without excessive heating. Its nominal speed is 2000 rpm, which fits many packaging, conveying, and metalworking drive ratios.

For static position retention, the integrated blocking brake supplies 6.5 Nm of countertorque to resist drift when power is removed. Position data is returned to the drive through Digital servo feedback (DSF), providing rotor information for accurate speed and position control throughout the operating range. Mechanical power is transmitted through a plain shaft, and a fitted shaft seal helps keep lubricant in the bearing area while limiting the entry of fine dust. The brake and feedback system allow the axis to remain controlled during holding, restarting, and short positioning moves.
