Product Description:

The MDD071A-N-030-N2S-095GL0 is a synchronous servo unit from the MDD Synchronous Motors series produced by Bosch Rexroth Indramat. Classified as a motor for digital drive controllers, it converts electrical commands from the drive into mechanical rotation in automated machinery. Its design supports precise speed and torque regulation for positioning tables, pick-and-place axes, and packaging spindles where fast response and integrated feedback are required. The synchronous construction also helps the motor maintain accurate motion under changing load conditions without requiring external feedback hardware.

A centering flange of 95 mm aligns the housing to gearboxes or mounting plates and helps keep shaft runout low after installation. Under thermal steady state, the rotor can supply 2.2 Nm of continuous standstill torque, which helps set the operating range of the matching drive. The motor reaches a nominal speed of 3000 rpm, allowing connected axes to maintain stable linear or rotary motion during repetitive cycles. Position and velocity data are returned through Digital servo feedback (DSF), so the controller can monitor rotor movement directly. All power and signal conductors exit on the left side, which can simplify cable routing in cabinets that follow a left-to-right layout.

The motor uses frame size 071, which suits lighter mechanical loads and smaller coupling arrangements than larger housings in the same family. Its length code of A indicates the shortest stack in this frame size, which helps reduce mass and rotor inertia for quick acceleration and deceleration. Torque is transmitted through a plain shaft, making the output suitable for direct coupling methods that do not require a keyed interface. The motor also has a shaft seal, which helps limit the entry of oil or coolant at the bearing area when the unit is mounted to machinery. Because the model is supplied without a blocking brake, any vertical axis must use an external holding method when power is removed.
