Product Description:

The MDD090B-N-020-N2L-110GA0 is a synchronous servo motor developed by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers controlled rotary motion for indexing tables, material-handling axes, and other automated stations. A 090-frame diameter and B-length stack create a compact profile, while the standard housing and standard rotor balancing allow direct mounting inside machinery that demands repeatable positioning with limited vibration. Its synchronous design allows fast torque response during starts, stops, and short positioning moves.

The motor has a nominal speed of 2000 rpm and a continuous standstill torque of 7.2 Nm. The standard balancing class limits residual unbalance so the machine frame is not excited at operating speed. Precise concentricity is aided by the 110 mm centering pilot, which positions the stator concentrically with adjoining mechanics. All electrical terminations are located on Side A, and a keyed connector system allows quick attachment and removal of power and feedback lines. A plain aluminum housing promotes natural convection, and internal winding sensors work with the controller to monitor motor temperature during operation.

The output shaft carries a shaft seal that prevents splash fluids from reaching the front bearing, and the rotor has a plain shaft that is suitable for clamp couplings or gear hubs. Because the unit is delivered without a blocking brake, any static holding duty must be handled by an external brake or by the drive’s regenerative torque. High-resolution position signals are transmitted through digital servo feedback, which supports accurate low-speed control and stable response during load changes. There is no shaft extension on side B, which helps simplify the motor layout for direct machine integration.
