Product Description:

The MDD071C-N-040-N2M-095GB1 is a synchronous servo motor produced by Bosch Rexroth Indramat for the MDD Synchronous Motors series. Designed to pair with digital drive controllers, it supplies commanded torque and velocity to automated feed axes, pick-and-place arms, and other precision stations on the factory floor. Its task is to translate electric control signals into tightly regulated rotary motion so that downstream mechanisms follow programmed profiles with minimal position error.

The motor can deliver a continuous standstill torque of 6.6 Nm, allowing it to support static loads without overheating when the shaft is locked in position. During motion, the rotor reaches a nominal speed of 4000 rpm, which suits high-cycle equipment that requires fast operating speeds. Mechanical centering is simplified by a 95 mm centering diameter that mates with standard mounting flanges to keep the stator concentric with the bearings. Power and feedback cables exit on side B, which can simplify conductor routing on machines where the opposite face must remain clear. An integrated multi-turn absolute encoder tracks shaft position over many revolutions, enabling the controller to recover the exact angle after power interruptions without homing routines.

When motion stops, the built-in blocking brake supplies 3.0 Nm of holding torque, so vertical or suspended loads can remain stationary after the drive is disabled. Closed-loop regulation is maintained through digital servo feedback, which transfers precise position data at high update rates to the amplifier. The rotor ends in a plain shaft that accepts couplings or pulleys without keyways, and a protective shaft seal prevents dust or coolant from entering at the bearing interface. Standard dynamic balancing supports smooth rotation across the motor’s operating speed range.
