MDD071B-N-040-N2S-095GL1
The MDD071B-N-040-N2S-095GL1 is a synchronous servo motor manufactured by Bosch Rexroth Indramat and supplied within the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it converts drive output current into precise rotary motion for positioning or speed-regulated axes in automated machinery. The 071 frame size with B length gives it a compact form that suits indexing units, feed axes, and other machines that need accurate starts, stops, and speed changes. Because it is intended for closed-loop operation, the motor works with the drive to maintain commanded speed and position when load conditions shift during the motion cycle.
The flange centering diameter measures 95 mm, so mounting hardware can locate the stator housing without additional alignment aids. Power and feedback cables exit on the left side because the factory-installed connection direction is oriented that way, which can simplify routing when multiple axes are installed close together. A single multi-pin connector carries phase conductors and auxiliary signals, reducing cable count and saving installation space around the motor. At standstill, the electromagnetic package develops 4.4 Nm of continuous torque, allowing the axis to support steady loads during controlled operation. Under nominal operating conditions, the rotor reaches 4000 rpm, which suits medium-speed positioning and indexing duties. The side-oriented cable exit also helps keep bending space predictable near cabinet walls or guarding panels. Standard dynamic balancing helps keep vibration low, and the motor housing uses the common cylindrical form of the series.
Feedback to the drive is provided through integrated digital servo feedback, enabling tight velocity control and position monitoring during operation. Motion can be held after power is removed because the blocking brake supplies 3.0 Nm of static braking torque, which supports vertical or suspended loads within the motor's intended size class. The output uses a plain shaft for clamp-style couplings, and it is supplied with a shaft seal to limit lubricant escape and the entry of dust along the shaft journal. This combination supports clean power transmission at the coupling and helps protect the bearing area during repeated duty cycles. The sealed shaft arrangement is useful where airborne debris or light contamination is present around the coupling area.
