Product Description:

The MDD071A-N-030-N2S-095PL1 is a synchronous servo motor produced by Bosch Rexroth Indramat within the MDD Synchronous Motors series. Classified as a motor for digital drive controllers, it converts controlled electrical energy into rotary motion for coordinating axes, feeders, and indexing tables in automated production lines. Its mechanical envelope and electronic feedback are arranged for direct coupling to Rexroth inverters, enabling closed-loop speed and torque regulation without external transducers. This layout supports compact actuator arrangements that must repeat positions under moderate load while using a single-cable connection.

Its centering pilot is 95 mm, which helps keep alignment concentric against gearboxes or adapter flanges while matching the standard housing contour for size 071 frames. The rotor is balanced to the standard grade, limiting vibration at the rated 3000 rpm nominal speed. Power and feedback exit on the left side through a keyed connector, which helps keep cable routing orderly inside control cabinets. At standstill, the motor delivers 2.2 Nm of continuous torque, allowing holding or slow-feed operation without thermal derating. Position and velocity data are returned over digital servo feedback (DSF), giving the controller the resolution needed for tight speed regulation. The A length code shortens the active stack, and the standard shaft end is provided only on side A to reduce overhung load.

For vertical orientations, the integrated brake supplies 3.0 Nm of static torque once supply power is removed, preventing back-driving of suspended loads. Motion is transferred through a keyway shaft, and bearing life is supported by construction supplied with a shaft seal to help keep lubricants in and contaminants out. This motor is suitable for installations that require secure load holding after shutdown while also protecting the bearing area from ordinary machine debris.
