MDD071A-N-040-N2S-095PL1
MDD Synchronous Motors
The MDD071A-N-040-N2S-095PL1 is a synchronous AC motor manufactured by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed as a motor for digital drive controllers, it converts commanded current into precisely regulated rotary motion for conveying, tooling, and positioning equipment. The unit uses permanent-magnet excitation, includes an integrated blocking brake for safety during power-off conditions, and forms a compact actuator that links directly with Indramat servo amplifiers in automated production cells.
Mechanically, the motor mounts through a centering pilot of 95 mm, ensuring repeatable alignment on machinery frames. Its standard rotor balancing keeps vibration low, while the size code 071 and length code A maintain a compact envelope for rapid cycling. A continuous standstill torque of 2.2 Nm can be delivered without exceeding thermal limits, and the nominal operating speed reaches 4000 min⁻¹ for high-speed positioning. Power and feedback leads exit on the Left side through a single locking connector, streamlining cabinet layout. Closed-loop control is handled by the integrated digital servo feedback (DSF), which transmits absolute position data to the drive and permits fine velocity regulation during incremental moves.
The mechanical interface is rounded out by a keyway shaft that simplifies coupling to pulleys or gear sets, and a fitted shaft seal that blocks lubricant egress when the standard housing is mounted in wash-down or dusty lines. The integrated blocking brake supplies 3.0 Nm of static holding torque, allowing suspended loads to remain fixed when power is removed. A single shaft end on side A keeps the back of the motor clear for tight installations, while the standard housing supports smooth operation throughout frequent acceleration cycles.
