MDD071B-N-060-N2S-095PA0
The MDD071B-N-060-N2S-095PA0 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Intended for use with digital drive controllers, the unit supplies controlled mechanical power for positioning tables, packaging stations, and machining axes in industrial automation where high rotational speed and feedback accuracy are required. Its construction matches the electrical characteristics of Indramat inverter modules, allowing a fast dynamic response and consistent torque delivery across demanding duty cycles. This makes it suitable for applications that require accurate acceleration, stable speed regulation, and repeatable motion over frequent start-stop cycles.
At its rated operating point, the motor delivers 4.4 Nm of continuous standstill torque and can reach a nominal velocity of 6000 rpm when synchronized to the drive frequency. A centering flange diameter of 95 mm provides repeatable concentricity between the stator frame and the coupled machine element. Position and velocity information are returned through Digital servo feedback (DSF), enabling the controller to regulate speed and position accurately during rapid axis motion. This feedback arrangement helps the drive correct position error quickly and maintain stable rotation through speed changes. Cables exit on Side A, and a plug-style Connector supports rapid exchange without disturbing fixed conduit runs. The rotor is balanced to a standard quality grade, and the cast-aluminum housing uses a closed design that conducts heat to the mounting surface.
The output shaft uses a keyway so pulleys or couplings can be locked against slip, and it includes a shaft seal that helps block coolant or oil from entering the bearing chamber. Because the unit is supplied without a blocking brake, static holding force must be generated elsewhere in the machine. Size code 071 and length code B give the motor a compact inertia profile that fits restricted installation spaces inside modular drive frames and other tightly packaged machine sections.
