Product Description:

The MDD090B-N-040-N2M-130PR1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it supplies rotational power and position feedback to automated machinery that requires coordinated motion. Within an axis group, the unit converts electrical energy from the drive into mechanical torque that can be finely regulated, allowing conveyor sections, handling modules, or packaging stages to maintain commanded profiles under varying load conditions. This arrangement supports repeatable starts, stops, and speed changes in machines where several axes must work in step.

Its mechanical interface includes a centering diameter of 130 mm, standard balancing, and a shaft end without a side-B extension to simplify coupling alignment. Power and feedback conductors exit on the right side through a keyed connector, so cable routing can remain compact in tightly arranged machine layouts. The rotor can reach a nominal speed of 4000 rpm, and at standstill it sustains 7.2 Nm of continuous torque without overheating, giving stable force for clamping or indexing tasks. Motor size 090 with length code B keeps the housing compact while still fitting typical assembly-cell installations.

The motor includes a blocking brake rated at 6.5 Nm to help prevent back-driving during power-off conditions. Position information is generated by an integrated multi-turn absolute encoder and routed to the controller as digital servo feedback (DSF), enabling immediate synchronization after every restart. An internal shaft seal helps keep lubricant inside and contaminants out, while the keyway shaft profile provides positive mechanical locking to pulleys or couplings. The seal also helps protect the bearing area during regular operation in enclosed machinery.
