Product Description:

The MDD090A-N-040-N2M-110GL0 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Intended for pairing with digital drive controllers, it converts electrical commands into controlled rotation for industrial automation. The 090 frame and A-length housing minimize the footprint while supporting precise motion in packaging, pick-and-place, and general handling axes. This compact layout helps the motor fit tightly spaced machine assemblies where responsive positioning and repeatable motion are required. Its synchronous design also supports smooth speed regulation and stable torque response during repeated start-stop cycles.

At its rated operating point, the motor reaches a nominal speed of 4000 rpm, allowing rapid positioning on fast-cycling axes. The continuous standstill torque is 3.7 Nm, so the motor can maintain commanded force at zero speed during regulated holding periods. A centering diameter of 110 mm supports accurate alignment with the mating machine surface. Rotor position is reported through an integrated multi-turn absolute encoder, which allows the controller to retain position information across multiple revolutions. The motor is supplied without a blocking brake, so any load holding during power-off conditions must come from the drive or from external mechanical devices.

Power and feedback conductors exit on the left side through a rugged connector, which helps keep cable routing predictable in compact installations. Feedback signals use digital servo feedback (DSF), so the controller receives precise position data for closed-loop speed and position control through the motor interface. The output uses a plain shaft with a shaft seal that helps limit lubricant escape and reduce contaminant entry at the shaft opening. A single shaft end on side A keeps the mechanical layout straightforward for direct coupling to driven equipment. The standard housing arrangement keeps the motor compact and leaves more room around adjacent machine components.
