Product Description:

The MDD071B-N-N2T-095PA4 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for pairing with digital drive controllers, the unit converts drive current into rotary motion for positioning or speed-regulated tasks in automated machinery. Its standard housing, keyed output shaft, and IP-rated sealing make it suitable for enclosed production lines where compact actuation and direct mechanical coupling are required. This motor format is commonly used on feed axes, indexing tables, and similar mechanisms that require repeatable closed-loop motion in limited installation space.

The motor sustains a continuous standstill torque of 4.4 Nm, giving machine axes holding force without excess heating during dwell periods. Accurate alignment to gearboxes or fixtures is supported by a centering diameter of 95 mm, while the shaft itself is sized at 25 mm to match common couplings referenced in DIN 748 Section 3. A keyway dimension of 6 × 6 × 32 mm conforms to DIN 6885-A, transferring torque to pulleys or pinions without slip. Environmental protection is rated at IP65, so dust ingress and low-pressure water jets will not impair the bearings or feedback electronics. The combination of the centering fit and keyed shaft helps maintain stable alignment between the motor and the driven load. Power enters from Side A of the stator housing, simplifying cabinet cable routing when the motor is mounted with its length code B frame.

Additional interface details include a center-hole thread of M3-8 that accepts fixture bolts tightened to 2 Nm, allowing precise axial retention of the shaft during assembly. Position data is supplied through a DSF with a multiturn absolute encoder, enabling the controller to recover true position after power cycles without homing routines. The motor maintains all ratings up to a maximum installation height of 1000 m ASL, ensuring thermal limits are respected in most factory settings even when cabinets are placed on elevated mezzanines. This feedback arrangement supports applications that must resume operation with the axis position already known to the control system.
