Product Description:

The MDD090A-N-030-N2M-130PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Intended for use with digital drive controllers, this unit supplies controlled torque and speed to automation equipment such as indexing tables, pick-and-place heads, and light conveyor zones. Its electromechanical design combines permanent-magnet excitation with encoder feedback so that the connected drive can regulate motion with millisecond-level accuracy under changing load conditions. Because the motor shares mounting and electrical conventions with other MDD models, it fits established flange and cable layouts used across the series.

The centering pilot is 130 mm, providing the reference surface that keeps the stator coaxial with the driven mechanics. Power and feedback conductors exit on Side A through a connector. Standard balancing limits residual vibration, while the housing tolerates typical plant atmospheres without auxiliary shrouds. Under continuous stall, the motor generates 3.7 Nm of torque, which is suitable for tensioning or holding duties. Rotor position is captured by an Integrated multiturn absolute encoder, and that signal travels to the controller as Digital servo feedback (DSF), permitting closed-loop control down to single-count accuracy. A shaft seal guards the bearing set against emulsified fluids.

With size code 090, the motor is optimized for compact cells, and the rotor can reach a nominal speed of 3000 rpm during cyclic operation. Torque is transmitted through a keyway shaft, and the shaft end uses the standard single-sided form. The unit is delivered without a holding brake, so systems that need mechanical locking must use an external clamp or electromechanical brake. Motor length code A identifies the shortest build in the family, saving axial space inside cabinets.
