MDD071B-N-040-N2T-095PA2
The MDD071B-N-040-N2T-095PA2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat as part of the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts electrical input from the drive into controlled mechanical motion so automated handling modules, packaging axes, or tooling spindles can be positioned with repeatable velocity and torque during normal machine operation. All connectors exit on Side A, which keeps the power and feedback connections on one side of the installation and can simplify cable routing around the motor.
This model delivers a continuous standstill torque of 4.4 Nm, allowing the axis to hold a static load without overheating during dwell periods. A rated speed of 4000 rpm is the top rotational velocity under nominal voltage and load, which suits fast-cycle machining or conveyor tasks. Position data is returned through digital servo feedback (DSF), enabling the controller to close the position and velocity loops with high resolution. Mechanical alignment is supported by the 95 mm centering diameter that helps locate the flange accurately on the machine frame. The motor also uses a standard housing, standard dynamic balancing, a connector-based power and feedback interface, a single shaft end, and a built-in shaft seal that helps limit dust or coolant ingress.
The motor is supplied with a blocking brake that produces 6.5 Nm of holding torque for vertical or safety-critical axes when power is removed. An integrated multi-turn absolute encoder stores position over multiple revolutions, so homing is not required after shutdown. The shaft is machined with a keyway to transmit torque into couplings or pulleys without slip. Its physical envelope matches size code 071 with length code B, giving the motor a compact profile for moderate load inertia ratios. The balancing, housing, and shaft-end arrangements remain in the standard configuration so the motor fits existing MDD mounting patterns.
