Product Description:

The MDD071B-N-040-N2T-095GR0 is a synchronous servo motor built by Bosch Rexroth Indramat within the MDD Synchronous Motors series. It is intended for digital drive controllers where precise velocity and position control are needed on packaging lines, pick-and-place gantries, or light machine-tool axes. By supplying closed-loop torque and speed, the motor converts electrical commands from the drive into repeatable mechanical motion for automated equipment. This operating principle lets the drive correct speed error and position deviation in real time, which is useful on axes that start and stop frequently.

A centering diameter of 95 mm lets the housing seat accurately in standard motor flanges. Its continuous standstill torque of 4.4 Nm indicates the sustained load the rotor can hold without overheating. The rotor can reach a nominal speed of 4000 rpm, allowing high surface velocities on small transmission components. Power and feedback conductors exit on the right side, and the signal bundle terminates in a keyed connector that helps prevent incorrect mating. Standard dynamic balancing limits residual vibration across the working speed range, while the plain shaft geometry mates directly with backlash-free couplings.

The unit is supplied without a blocking brake, so any static holding force must come from the drive or an external clamp. The motor has frame code 071 and length code B, which correspond to its core diameter and active stack depth. Position data is returned through Digital servo feedback (DSF), meaning the integrated multi-turn encoder sends absolute position values over a serial channel to the drive. A shaft seal is fitted to protect the interior bearings from coolant splash and airborne particulates, which helps preserve lubrication under typical factory conditions.
