Product Description:

The MDD090B-N-020-N2L-110PL0 is a three-phase synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts electrical power into controlled rotary motion for automated machine axes, pick-and-place heads, and material-handling stages. The unit operates with permanent-magnet excitation and closed-loop feedback so it can hold commanded positions, track velocity profiles, and deliver repeatable motion under changing loads inside industrial automation systems. This operating style suits synchronized positioning tasks that rely on accurate response to command changes.

At its rated operating point, the rotor reaches a nominal speed of 2000 rpm, meaning the shaft completes two thousand revolutions each minute under rated conditions. During a locked-shaft condition, it can apply 7.2 Nm of continuous torque without exceeding the permissible winding temperature. The flange includes a centering diameter of 110 mm that aligns the motor precisely with gearboxes or mechanical mounts and keeps radial deviation low. Power and feedback conductors exit on the left side, simplifying cabinet wiring on machines that place drives on that side. Position information is returned through digital servo feedback, allowing the controller to monitor position and respond to load changes in real time.

Standard balancing limits vibration, while a detachable connector interface replaces fixed leads and simplifies installation. The output shaft uses a keyway so couplings can lock directly onto the shaft, and a durable shaft seal helps protect the internal bearings from coolant or dust. The motor is delivered without a blocking brake, so any static holding force must come from the drive or an external mechanism. The housing is standard, the motor length code is B, the frame size is 090, and the shaft end is present only on side A, leaving side B closed. This layout keeps the non-drive end enclosed when only one shaft extension is needed.
