Product Description:

The MDD112D-N-020-N2M-130GB0 is a synchronous servo motor in the MDD Synchronous Motors series produced by Bosch Rexroth Indramat for use with the manufacturer's digital drive controllers. It converts regulated three-phase power into precise rotary motion for automated presses, packaging lines, and handling axes. Closed-loop operation lets the motor respond quickly to changing commands while maintaining smooth motion during positioning and speed regulation. That operating behavior is useful on axes that repeat short move profiles throughout a production cycle.

At standstill, the rotor delivers a continuous torque of 38.0 Nm, supporting loaded axes while drive current remains applied. Speed commands up to 2000 rpm suit medium-speed positioning tasks that also require solid torque output through the operating range. Power and feedback terminations are routed on side B of the frame, which helps keep cable routing away from couplings and driven components in many installations. The flange includes a centering pilot of 130 mm for accurate alignment with the machine plate. This locating feature helps maintain shaft alignment when the motor is mounted directly to a gearbox or machine face. Position data reaches the controller through digital servo feedback (DSF), allowing the drive to regulate speed and position without a separate external feedback device.

High-resolution commutation signals originate in an integrated multi-turn absolute encoder, so rotor position remains available immediately after power is restored. The motor uses a plain shaft that works with clamp or shrink-fit couplings, and it is supplied with a shaft seal to help limit lubricant escape and contaminant entry at the shaft opening. Because the unit comes without a blocking brake, any load that must stay fixed during power-off conditions needs an external holding method. For vertical or suspended loads, a separate brake or mechanical lock is typically used when the servo is de-energized. The D-length housing extends the active motor section, which supports higher torque output in this frame size while preserving the standard flange interface.
