Product Description:

The MDD071B-N-040-N2S-095GR2 is a synchronous servo motor built by Bosch Rexroth Indramat for the MDD Synchronous Motors series. It is classified as a motor for digital drive controllers. The unit converts drive current into regulated mechanical motion for automated positioning or speed-regulated axes on machinery. Its synchronous design supports coordinated motion in machines that require stable response and accurate regulation.

The motor has a centering diameter of 95 mm that fits standard pilot recesses, and the rotor is balanced to the manufacturer's standard grade to minimize vibration. Power and feedback conductors exit on the right side, and a molded connector simplifies cable replacement while keeping the connection compact. A shaft seal is installed to limit dust or coolant ingress, and the housing uses the standard enclosure style for the series. The motor uses digital servo feedback so the drive can read absolute position data without external encoders. It has a plain shaft without a secondary side-B extension, which suits inline couplings. Continuous torque at standstill reaches 4.4 Nm, allowing the motor to hold or slowly move a load at rated current without thermal overload. During motion, the winding supports a nominal speed of 4000 rpm, giving headroom for moderately fast traverse moves in pick-and-place units or packaging stations.

Load-holding capacity when power is removed comes from an integrated blocking brake that generates 6.5 Nm of static torque, which helps prevent vertical or suspended axes from drifting. The design follows length code B, so the stator stack is the medium-length variant within the 071 frame family. This keeps inertia lower than longer codes while still exceeding the torque of the short version. The standard housing, connector orientation, and digital feedback allow closed-loop control with compatible Indramat drive controllers.
