Product Description:

The MDD071A-N-030-N2S-095GR2 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Delivered as a motor for digital drive controllers, it converts precisely regulated current into torque for automated machinery. Integrated electronic feedback and standardized mechanical interfaces allow the unit to fit compact positioning axes and material-handling modules that require repeatable velocity control and coordinated multi-axis operation. Its operating profile suits feed systems, small transfer axes, and indexing units that need smooth acceleration with consistent response from cycle to cycle. The motor is intended for installations where compact dimensions and dependable closed-loop motion are more important than oversized torque reserve.

Nominal rotor speed reaches 3000 rpm, matching drive systems that switch between rapid traverse and fine-feed modes without recalibration. At standstill, the motor can supply 2.2 Nm of continuous torque under thermal steady-state conditions in its standard housing. The mechanical interface uses a centering shoulder of 95 mm, which helps maintain coaxial alignment with gearheads or flange plates. Frame size 071 corresponds to the stator diameter used for this housing. Position and speed data are transmitted through Digital servo feedback (DSF), so the connected controller can close fast loops without external encoders. This feedback arrangement supports stable velocity regulation when load conditions change during normal machine operation.

For static holding or emergency stops, the integrated blocking brake delivers 6.5 Nm of torque and engages automatically when supply power is removed. Power and feedback conductors exit on the right side through a sealed connector, which helps with cable routing in tight cabinets. The motor uses a plain shaft with a factory-fitted shaft seal to reduce the chance of lubricant migration into the motor. The shaft end on side B is omitted, which matches the standard single-ended arrangement used for this model. Motor length code A is the shortest stack in the series, which helps limit inertia while preserving useful thermal capacity. Standard housing surfaces and the connector style support direct installation in compact machine layouts.
