Product Description:

The MDD071B-N-030-N2T-095GL2 is a synchronous AC servo motor manufactured by Bosch Rexroth Indramat and assigned to the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it provides closed-loop torque and speed for automated handling equipment, indexing tables, and light-duty machining centers. An integrated multi-turn absolute encoder relays shaft position across multiple revolutions, allowing the controller to restore the exact orientation after a power loss without homing moves.

This model delivers a continuous standstill torque of 4.4 Nm, enabling steady axial loads while stationary. At rated electrical frequency, the rotor reaches a nominal speed of 3000 rpm, matching drive stages that operate on 50/60 Hz supplies and medium bus voltages. The flange has a centering diameter of 95 mm, which simplifies concentric alignment to gearboxes or direct-drive loads. It uses standard balancing, so additional vibration trimming is not required when the plain shaft is coupled to compliant elements. All power, brake, and feedback conductors exit through a connection on the left side that terminates in a sealed circular connector. The housing has a standard protective finish, and the encoder housing is integrated into the same frame to minimize axial length.

An electromechanical blocking brake supplies 6.5 Nm of holding torque, retaining vertical axes at rest without external clamps. The motor follows size code 071 and length code B, giving it a compact body that fits into narrow machine spaces while still accommodating the internal winding mass. Position data are returned through digital servo feedback, which carries incremental and absolute data to compatible Indramat drives over a two-wire channel. A shaft seal protects the front bearing from emulsified cutting fluids, and the plain shaft end is provided only on side A.
