Product Description:

The MDD093A-N-020-N2M-130GL2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It serves as the rotary actuator for digital drive controllers, translating command currents into controlled motion for indexing tables, gantry axes, and other automated stations in industrial environments. Its synchronous design supports accurate speed and position control in machinery that requires repeatable motion over long operating cycles. This makes it suitable for transfer systems, packaging equipment, and handling axes where the drive must respond smoothly to changing load conditions.

A centering diameter of 130 mm positions the motor precisely on its mounting face, while power and feedback conductors are routed on the left through a sealed connector. The rotor reaches a nominal velocity of 2000 rpm, allowing moderate-speed cycles without overspeeding the mechanical structure. At standstill, the windings deliver 9.2 Nm of continuous torque, giving stable force for holding loads or supporting slow-feed movements. When the line is de-energized, an internal blocking brake supplies up to 22 Nm of restraining torque, which helps prevent unintended shaft rotation on vertical or safety-critical axes. The motor uses standard balancing and a standard housing without external cooling fins or an enlarged frame.

Closed-loop accuracy is maintained with digital servo feedback (DSF) generated by the integrated multiturn absolute encoder, which reports position across multiple revolutions without battery support. Because the encoder is absolute, the control system can retain position information through power cycles without a reference move. Mechanical coupling is direct because the unit is built with a plain shaft, eliminating keyways that could introduce backlash, and a fitted shaft seal blocks lubricant migration and particle ingress at the housing exit. The shaft is present only on the drive side, so there is no shaft end on side B. Motor length code A keeps the overall depth short for compact machinery, and motor size 093 matches this frame to compatible drives.
