Product Description:

The MDD071A-N-030-N2S-095GA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It interfaces directly with digital drive controllers, converting commanded currents into precise rotary motion for automated assemblies, indexing tables, and light conveyor axes. By combining electrical-to-mechanical conversion and position feedback in one housing, the unit supports coordinated axis motion in compact automation systems. This arrangement helps the drive react quickly to command changes and maintain smooth motion during repeated start-stop cycles.

At rated excitation, the motor supplies a continuous standstill torque of 2.2 Nm, allowing small fixtures or feed rollers to remain loaded without overheating. Its nominal operating speed reaches 3000 rpm, which suits common inverter outputs and supports mid-range spindle or gear ratios. Frame code 071 identifies the stator outside diameter, giving the motor a repeatable installation envelope within this series. Mounting accuracy is aided by a 95 mm centering diameter, which locates the flange concentrically to the shaft when the motor is bolted to a machine plate. This supports stable coupling alignment and consistent mechanical fit on the driven assembly.

For position retention during power-off states, a blocking brake generates 6.5 Nm of static torque and helps prevent drift on vertical or overhung loads. Rotor position is transmitted through digital servo feedback (DSF), enabling the controller to close current and velocity loops with accurate rotor data. Power and signal connectors are oriented on Side A, which can simplify cable routing when several motors line up along one machine face. A shaft seal is installed at the output end to help keep lubricants inside the bearing cavity and reduce coolant splash entry. The drive end uses a plain shaft, allowing clamp couplings or press-fit pulleys to be mounted without keyway alignment constraints.
