Product Description:
The MDD071B-N-030-N2S-095GL2 synchronous motor is manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it converts drive current into mechanical motion for positioning tasks in automated assembly cells, pick-and-place stations, and packaging lines. Its design pairs directly with Rexroth drives, allowing deterministic position feedback and compact installation inside machine frames. This makes it suitable for axes that require repeatable movement without a large installation footprint. It can be used where the motor and drive must maintain stable motion during short indexing sequences.
At its rated operating point, the motor reaches a nominal speed of 3000 rpm, allowing direct coupling to gearless mechanisms that demand consistent velocity. A continuous standstill torque of 4.4 Nm supports static holding loads while limiting excess heat at zero speed. When power is removed, an integrated blocking brake supplies 6.5 Nm of mechanical restraint to help prevent axis drift. The centering shoulder measures 95 mm, providing accurate concentric alignment with flange mountings. Position data is returned through digital servo feedback (DSF), so the drive can correct small positional errors in real time. A shaft seal at the output end helps limit the entry of dust or fluids in demanding work areas.
Cabling is routed to the housing’s left side, and both power and feedback lines terminate on a single connector, which helps keep wiring compact around the motor body. The smooth plain shaft interface mates with backlash-free couplings for direct torque transfer. Size code 071 and length code B set the motor’s envelope for this frame. A standard aluminum housing helps conduct heat away from the stator during normal operation. The single-connection layout reduces the number of separate cable entry points at the machine. The absence of a secondary shaft on side B leaves more clearance at the rear of the motor in tight machine compartments.
