Product Description:

The MDD090B-N-040-N2L-110GB0 is a synchronous servo motor produced by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Designed as a mechanical actuator for digital drive controllers, the unit converts regulated AC into controlled rotation for indexers, packaging heads, and material-handling axes in industrial automation. Standard housing dimensions and balancing let the motor mount directly on machinery frames, while its interface allows coupling to gearboxes or pulleys without special adapters.

Its rated operating point is a nominal speed of 4000 rpm, enabling rapid cycle times when paired with high-frequency drives. At standstill, the motor can deliver a continuous torque of 7.2 Nm, so it can hold loads without overheating during dwell periods in pick-and-place sequences. A centering diameter of 110 mm forms the locating shoulder that aligns the stator concentrically in flange mounts and keeps runout within permissible limits. Power and feedback conductors exit on the rear because the connection hardware is positioned on side B. A keyed connector simplifies cable attachment, while the size-090 frame and length code B set the overall footprint and thermal mass for the listed output figures.

Closed-loop position control is obtained through digital servo feedback, which supplies high-resolution rotor angle data to the drive for real-time current modulation. The motor is supplied without a blocking brake, so external holding devices or drive torque must secure vertical loads when power is removed. A plain shaft reduces frictional losses, and the presence of a shaft seal protects the internal bearings from coolant splash or airborne particulates. The shaft end on the drive side follows the series standard geometry, and no shaft extension is provided on the opposite side, keeping the overall length compact for tight machine envelopes.
