Product Description:

The MDD071B-N-040-N2S-095GR1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. As a motor intended for digital drive controllers, it delivers controlled rotary motion to automated axes found in packaging lines, pick-and-place stations, and similar industrial equipment. The device integrates feedback, mechanical, and braking features so that drive amplifiers can apply closed-loop velocity and position commands without external transducers. This arrangement supports accurate axis response in machines where installation space is limited.

Its mechanical interface uses a 95 mm centering diameter that aligns the stator flange to mounting fixtures. Power and feedback cabling exit on the right side through a sealed connector, simplifying cable routing in multi-axis groups. During continuous stall conditions, the motor sustains 4.4 Nm of torque, allowing modest holding force while current is limited by the drive. Under rated supply, the rotor reaches 4000 rpm, a speed suited to high-frequency applications such as spindle indexing. The rotor is balanced to the standard quality grade, which helps limit vibration when coupled to a load. A standard housing and a shaft seal help protect the internal windings from airborne fluids and fine dust.

Additional features focus on safe stopping and accurate feedback. A factory-installed blocking brake clamps the shaft whenever control power is removed, and the unit develops 3.0 Nm of static braking torque to secure vertical or suspended loads. Position data is returned through digital servo feedback, so the drive can calculate displacement without external encoders. The single-ended, plain shaft uses the standard shaft-end arrangement and comes without a second shaft extension, which helps reduce overhung mass. Motor length code B, size 071, and the standard balancing class keep the overall envelope compact for tight machine frames.
