Product Description:

The MDD093B-N-020-N2M-130PA2 is a synchronous AC servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical power into axis rotation for positioning, feed, and spindle tasks in automated lines. By combining precise torque generation with encoder-based feedback, the unit supplies the closed-loop behavior required in CNC machines, packaging equipment, and material-handling systems. Its synchronous operating principle supports accurate speed regulation and repeatable motion during changing load conditions. This makes the motor suitable for axes that must start, stop, and reverse without losing position accuracy.

The mechanical frame follows the series size 093 with length code B and standard dynamic balancing. A centering flange diameter of 130 mm mates directly to gearboxes or mounting brackets, while the shaft is the standard end without a secondary extension. Power and feedback connectors are oriented on side A and use an industry-standard connector interface that simplifies cable routing in compact machine layouts. At rated operating conditions, the rotor reaches 2000 rpm and delivers a continuous standstill torque of 14.5 Nm. When the integrated blocking brake is energized, it can lock the shaft with 22 Nm of static torque to prevent unwanted movement at standstill. The housing uses the standard closed design in this motor line, which helps shield internal components during normal operation.

The feedback system uses an integrated multi-turn absolute encoder that records full revolutions, and its signals are returned through digital servo feedback (DSF) to the drive controller for high-resolution speed and position control. This feedback path sends rotor information directly to the controller, supporting stable speed loops and precise positioning across the operating range. Torque is transmitted through a keyway, and the output end is fitted with a shaft seal to limit lubricant escape and reduce the entry of contaminants at the shaft opening. The multi-turn encoder allows the controller to track position over repeated revolutions without relying only on incremental pulse counting. The keyed shaft supports positive torque transfer to couplings or hubs that use a matching key connection, and the sealed shaft area helps protect the bearing zone during regular machine operation.
