Product Description:

The MDD090A-N-020-N2M-110GA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current into controlled mechanical rotation for automated positioning and speed-control tasks on industrial machinery. Its standard housing and balanced rotor support direct installation in machine frames without special mechanical adaptation. This arrangement suits indexing tables, feed axes, and handling units that depend on consistent servo response during continuous operation.

At a nominal speed of 2000 rpm, the rotor reaches its synchronous operating velocity under rated conditions, while a continuous standstill torque of 3.7 Nm allows the axis to hold load when motion is paused. The 090 frame uses a 110 mm pilot diameter that aligns the motor to gearboxes or mounting faces and helps keep runout low. Electrical power and feedback conductors exit on Side A, and the molded connector interface keeps cable routing compact. Position data is supplied by an integrated multi-turn absolute encoder, so the controller retains absolute shaft position across power cycles. That reduces the need for reference travel after a restart.

The motor is supplied without a blocking brake, so external clamping or drive-produced torque must hold position when power is removed. Rotor position and diagnostic data are transmitted through digital servo feedback (DSF), providing high-resolution position data to the controller during closed-loop operation. The output uses a plain shaft combined with a shaft seal, which helps protect the bearings from dust and coolant spray while keeping the coupling interface simple. A sealed connector supports the standard drive-side shaft arrangement and suits continuous industrial service.
