Product Description:

The MDD093A-N-040-N2M-110PL2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it converts commanded current into rotary motion for positioning, feed-rate, and auxiliary axes in industrial automation. The unit is supplied with an integrated multi-turn absolute encoder so the controller can read shaft position directly without requiring an external feedback device. This arrangement supports accurate closed-loop motion control in applications that depend on repeatable speed and position response.

At standstill, the rotor can deliver 9.2 Nm of continuous torque, and the windings permit speed regulation up to 4000 rpm under rated conditions. A blocking brake is installed, and its mechanical holding torque is 22 Nm, which allows the motor to hold a load when power is removed. The rotor is balanced to the standard grade used for this series, which helps limit vibration during high-speed operation. Power is transmitted through a shaft with a keyway for positive-drive coupling, and the front bearing region is protected because the motor is supplied with a shaft seal.

The flange has a centering diameter of 110 mm, allowing direct mounting to gearboxes or machinery that follow ISO metric interfaces. Electrical and feedback leads exit on the left side, and the housing uses a sealed connector to simplify cable attachment without opening the enclosure. Position data is reported through digital servo feedback (DSF), giving the controller high-resolution information for tight speed loops. The motor length code A indicates the shortest stack in the 093 frame, which helps reduce mass and moment of inertia for rapid acceleration. A standard housing and a single shaft end on side A further simplify installation when only one drive element must be coupled.
