MDD071A-N-040-N2S-095GR1
The MDD071A-N-040-N2S-095GR1 is a three-phase AC synchronous motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Supplied as a motor for digital drive controllers, it acts as the rotary actuator on positioning tables, pick-and-place heads, and auxiliary spindles, turning command currents into tightly regulated motion for automated cells. Its compact frame simplifies integration into multi-axis assemblies where space and dynamic response are critical. This layout supports accurate starts, stops, and repeatable movement in compact production equipment.
During operation, the rotor can reach a nominal speed of 4000 rpm, giving production equipment short index times and smooth continuous feeds. At standstill, the electromagnetic stack sustains 2.2 Nm of torque, so the axis can support tooling or payload without excessive heating. Frame code 071 corresponds to the motor's stator diameter, and a centering pilot of 95 mm keeps the flange concentric with machine plates. High-resolution feedback is delivered by the integrated digital servo feedback system, enabling the controller to close its loops without an external encoder. Standard rotor balancing limits residual vibration, and the cast aluminum housing follows the standard profile for this motor class. A molded connector carries both power and signal conductors, which helps keep cable routing compact in crowded assemblies.
Wiring exits on the right side, allowing consistent cable routing across parallel axes. For power-loss holding, an internal blocking brake produces 3.0 Nm of torque to help prevent drift on vertical slides. The rotating assembly is protected from coolant ingress because the shaft is fitted with a shaft seal, and the output end is a plain shaft that mates directly with clamp or collet couplings. The A-length core keeps the housing short, and the shaft end is supplied only on side A. A single-plug connector arrangement also helps conserve space in tight enclosures.
