Product Description:

The MDD071B-N-030-N2S-095PR2 is a synchronous servo motor manufactured by Bosch Rexroth Indramat in the MDD Synchronous Motors series. Built for digital drive controllers, the unit delivers controlled rotary motion to feed drives, handling modules, and other positioning axes in industrial automation. Its housing uses a keyed shaft and a single connector so the device can be wired and mounted without extra adapters. Its speed rating supports repeatable cycle times while keeping the envelope size modest.

At continuous stall, the rotor can generate 4.4 Nm of torque, a level suited for mid-range feed forces without excessive heat rise. The rated mechanical output is reached at a nominal speed of 3000 rpm, allowing the drive to balance fine resolution with adequate traverse velocity. Electrical and feedback leads exit on the right side, an orientation that keeps the cable loop inside compact machine frames. The centering pilot measures 95 mm, ensuring concentric alignment with gearboxes or adapter flanges. Power is delivered through a shaft machined with a keyway, and the positive drive fit helps prevent slippage when reversing load direction.

When the axis must hold position after power is removed, the integrated brake supplies 6.5 Nm of static torque to maintain accuracy at standstill. Rotor position is returned to the controller through Digital servo feedback (DSF), letting the drive correct minute deviations caused by load changes or thermal drift. Mechanical proportions follow the motor length code B and frame size 071, giving the unit a predictable envelope across multiple power classes in the series. A shaft-mounted seal keeps coolant splash and airborne contaminants out of the front bearing cavity, and there is no shaft extension on the rear side, simplifying enclosure design. The rotor is balanced to a standard grade to limit vibration at speed.
