MDD071B-N-060-N2T-095PR0
The MDD071B-N-060-N2T-095PR0 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor for digital drive controllers, it supplies rotational power to axes that require high positioning accuracy in automated machinery. In typical motion systems, it converts regulated current into repeatable rotary movement for feed axes, indexing units, and handling equipment. The synchronous design supports stable response during repeated acceleration and deceleration in compact machine axes. The housing follows the standard MDD frame, and internal components are balanced to the standard grade so vibration at high speed stays within acceptable limits. A right-side connector carries both power and feedback connections, which helps keep cable routing on one side of the machine.
The motor develops a continuous standstill torque of 4.4 Nm. Under rated drive voltage, it reaches a nominal rotor speed of 6000 rpm. A centering diameter of 95 mm aligns the flange on mounting fixtures, and the shaft uses a keyway to help prevent slip between the motor and the driven element. Position information is transferred through digital servo feedback, allowing the drive to close velocity and position loops without external converters. The shaft is supplied without a side B extension, which helps reduce overhang mass at the non-drive end.
An integrated multi-turn absolute encoder tracks shaft position across power cycles, so the axis does not need a homing routine after downtime. The motor has length code B, which provides a compact housing depth for this frame while supporting the stated torque class. Frame size 071 places the unit in a common diameter class, and a resilient shaft seal helps keep coolant spray away from the bearing set. The motor is delivered without a blocking brake, so any static holding function must be provided by external hardware or by controlled drive torque during stops.
