Product Description:

The MDD071B-N-030-N2S-095PA1 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Designed for digital drive controllers, it converts regulated current from a compatible Indramat drive into precise rotary motion for positioning, indexing, and speed-controlled tasks in automated machinery and handling stations. Its synchronous design supports closed-loop axis control, so commanded speed and position can remain stable during repeated starts, stops, and load changes.

The motor delivers a continuous standstill torque of 4.4 Nm, which is the steady torque available without overheating while the shaft is held at zero speed. It reaches a nominal speed of 3000 rpm, giving the drive a common operating speed for repetitive production duty. A centering diameter of 95 mm helps align the housing concentrically with mating machine parts or gear units. The motor has a frame size of 071 and a length code of B, which establishes its mounting envelope and overall rotor package. Standard dynamic balancing helps reduce vibration at rated speed, and the integrated connector keeps power and feedback wiring compact while maintaining the enclosure seal.

A holding brake rated at 3.0 Nm helps keep the load in place during power-off conditions, which is useful on vertical or parked axes. Position information is returned through digital servo feedback, allowing the drive to monitor rotor movement and maintain closed-loop control accuracy. The front flange includes a permanent shaft seal that helps retain internal lubrication and limit the entry of airborne contaminants. Power and feedback conductors exit on Side A, which supports uniform cable routing along the machine structure. The motor also uses a keyed shaft end and a standard housing layout for straightforward mechanical integration with couplings and driven loads.
