MDD071A-N-040-N2M-095PB0
The MDD071A-N-040-N2M-095PB0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it delivers rotary motion to precision axes in industrial automation, including pick-and-place gantries, packaging stations, and similar equipment that requires accurate speed and position control. The motor has size 071 and the short length code A, which gives it a compact housing for installations where space is limited. Its synchronous design allows the paired drive to regulate torque and speed precisely during rapid indexing, short travel moves, and repeated positioning cycles.
Mechanical alignment is set by a centering pilot of 95 mm, keeping the flange true to the machine plate. Power and feedback conductors exit on Side B through a single connector, which keeps cable routing straightforward at the motor. At standstill, the rotor can supply 2.2 Nm continuously, allowing the axis to resist moderate static loads while energized. Under dynamic command, the shaft reaches a nominal speed of 4000 rpm for fast-cycle motion. Positional data returns to the drive through built-in digital servo feedback, so closed-loop current, velocity, and position regulation can respond with minimal delay.
The drive shaft uses a keyway for secure torque transfer to couplings, pulleys, or similar driven elements. Motion tracking relies on an integrated multiturn absolute encoder that records full revolutions and provides position information immediately after power-up. A shaft seal protects the front bearing against dust and coolant splash during normal machine operation. Because the unit is supplied without a blocking brake, holding force must be provided externally when the axis must remain fixed after power is removed. The motor has a single shaft end, which helps keep the rear of the housing compact.
