Product Description:

The MDD093B-N-020-N2M-130GB1 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It acts as the rotary actuator in digitally controlled drive systems, converting commanded current into precise mechanical motion for positioning and speed-regulated automation axes. The unit is suited for packaging machines, machine tools, and material-handling modules that require stable velocity control and accurate axis response. In closed-loop operation, it works with a matching drive to maintain repeatable motion during indexing, feeding, and continuous speed changes.

At stall, the motor can deliver a continuous torque of 14.5 Nm, allowing sustained holding force without excess temperature rise. The rated operating speed of 2000 rpm is the synchronous velocity under nominal load conditions. Accurate mechanical registration is provided by a centering diameter of 130 mm, so the flange mates directly with precision gearboxes or machine frames. All power and feedback conductors exit on side B, and the supply lines terminate in a sealed connector plug that supports orderly cable routing in compact cabinets. The frame size is 093, which balances thermal mass with dynamic acceleration for medium-inertia loads.

When motion must be held during power-off events, the integrated brake supplies 11 Nm of static torque to prevent axis drift until drive power returns. Position data reaches the controller through Digital servo feedback (DSF), and the absolute multiturn encoder lets the axis retain position information through shutdowns and restarts. An internal labyrinth and elastomer ring form the front sealing system, summarized as with shaft seal, to help protect the bearing area from coolant mist and fine dust. This feedback and sealing arrangement supports reliable operation during repeated starts, stops, and speed changes in enclosed production equipment.
