Product Description:

The MDD090A-N-040-N2L-130GL2 is a synchronous servo motor engineered by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended to operate with digital drive controllers, it converts precisely regulated stator currents into controlled rotor torque and speed for automated axes, pick-and-place heads, or auxiliary spindles. The motor belongs to the 090 frame class and follows the A length code, giving a compact solution when cabinet depth or mechanical envelope is restricted while still providing the thermal mass needed for continuous industrial cycles.

The unit reaches a nominal speed of 4000 rpm, allowing fast indexing or high surface rates in production machinery. At standstill, it sustains 3.7 Nm of continuous torque through the standard housing and cooling path. For emergency stops or vertical-axis security, the integrated blocking brake supplies up to 11.0 Nm of static holding torque. Accurate mechanical alignment is supported by a centering diameter of 130 mm, and all power and feedback conductors exit on the left side to simplify cable routing in cabinets arranged along a common gantry.

The motor connects through a keyed industrial connector, and rotor position is returned to the drive via digital servo feedback (DSF), enabling high-resolution electronic commutation and real-time error capture. A plain shaft eases coupling to low-backlash bellows or elastomer elements, while the front bearing region is equipped with a shaft seal to help prevent coolant mist or dust ingress. The shaft end is supplied in the standard form without a side-B extension, preserving axial stiffness for dynamic start-stop duty. Because the product type is a motor for digital drive controllers, its electrical time constants and encoder scaling are matched to the current-mode loops typical of Indramat drives.
